Resumo: O objetivo neste trabalho foi avaliar a aplicabilidade do método de análise da idade óssea vertebral, proposto por Caldas et al. (2007) nas diferentes regiões do país. Para isso, foram utilizadas radiografias cefalométricas laterais e radiografias carpais de 381 meninas e 336 meninos, com faixa etária variando entre 7 e 15.9 anos, pertencentes a arquivos digitais de seis clínicas de Radiologia Odontológica provenientes das cidades de Belém-PA, Fortaleza-CE, Recife-PE, Brasília-DF e Curitiba-PR. Nas radiografias cefalométricas laterais, os corpos das vértebras C3 e C4 foram medidos com o auxílio de uma análise computadorizada das vértebras cervicais inserida no programa de cefalometria digital Radiocef Studio 2 e as idades ósseas das vértebras cervicais foram automaticamente calculadas, utilizando as equações de regressão desenvolvidas por Caldas et al. (2007). Nas radiografias carpais, os eventos de ossificação da mão e do punho foram avaliados e as idades ósseas determinadas pelo método de Tanner e Whitehouse (TW3). Os dados foram encaminhados à análise estatística de variância e teste de Tukey (p<0,05) para comparar idade óssea vertebral, idade óssea carpal e idade cronológica. Os resultados obtidos revelaram que, em todas as regiões estudadas, a idade óssea vertebral não apresentou diferença estatística significante em relação à idade cronológica. Quando analisada a relação entre as idades ósseas, foi possível observar diferença estatística significante entre idade óssea vertebral e idade óssea carpal nos sexos masculino e feminino das regiões Norte e Nordeste, assim como no sexo masculino da região Centro-Oeste. No entanto, as diferenças não foram maiores que 0,61, 0,31 e 0,45 anos para as regiões Norte, Nordeste e Centro-Oeste, respectivamente.Com exceção do sexo masculino na região Norte e do sexo feminino na região Nordeste, não foi encontrada diferença estatística significante entre idade óssea e idade cronológica. Para as regiões Norte e Nordeste, as diferenças encontradas foram de 0,44 e 0,26 anos para o sexo masculino e feminino, respectivamente. Baseados nestes resultados, pôde-se concluir que as fórmulas desenvolvidas por Caldas et al. (2007), para avaliação objetiva da idade óssea pelas vértebras cervicais, se mostraram confiáveis e podem ser utilizadas na população estudada.
Abstract: The aim of this study was to evaluate the applicability of the formula developed by Caldas et al. (2007) in Brazilian subjects. The samples were taken from patient digital files of six Oral Radiological Clinics placed in Belém-PA, Fortaleza-CE, Recife-PE, Brasília-DF e Curitiba-PR. Lateral cephalometric and hand-wrist radiographs of 381 girls and 336 boys (aged 7.0 to 15.9 years) were selected. On the digital lateral cephalograms, the bodies C3 e C4 were measured using a cervical vertebral computerized analysis created in the software program of digital cephalometric analysis Radiocef Studio 2 and cervical vertebral bone age was calculated using the formulas developed by Caldas et al. (2007). Hand-wrist bone age was evaluated by the Tanner and Whitehouse method (TW3). An analysis of variance (ANOVA) and Tukey test were used to compare cervical vertebral bone age, hand-wrist bone age and chronological age (P <0.05). No significant difference was found between cervical vertebral bone age and chronological age in all regions studied. When analyzing bone age, it was possible to observe a statistically significant difference between cervical vertebral bone age and hand-wrist bone age for female and male subjects in the North and Northeast regions, as well as for male subjects in the Central West region, which were no more than 0,61, 0,31 e 0,45 years in the North, Northeast and Central West regions, respectively. No significant difference was observed between bone age and chronological age in all regions except for the male subjects in the North and female subjects in the Northeast, which were 0,44 and 0,26 years, respectively. We concluded that the formulas developed by Caldas et al. (2007) to objectively evaluate skeletal maturation are reliable and can be applied to Brazilian subjects.

Full textThe main objective of this doctoral dissertation is to advance in the study of the morphology and evolution of the cervical vertebrae in Hominoidea. To reach this objective we have performed four studies using bony material (vertebrae and crania) belonging to both extant hominoid species, and also including the scarce fossil remains that from sub-tribe Hominina. Up until now, the scarce fossil material has limited the capacity to reconstruct the evolutionary history of the cervical spine. Thus, on top of classical morphological studies, using both traditional and geometric morphometrics, we have also applied statistical methods based on the principles of the theory of the evolution such as morphological integration, modularity and responses to selection, as a complementary approach to the fossil record.The results obtained in these four studies indicate that the morphology of the cervical vertebrae is related to postural and locomotor factors. These factors could have influenced the differences observed in the morphological and allometric patterns showed by H. sapiens regarding the rest of the hominoids. Also, the results from the analyses of integration and modularity indicate that there are differences in the pattern of integration showed by modern humans compared to that of the non-humans hominins (Pan and Gorilla). We consider that, despite some subtle differences, chimpanzees and gorillas could represent the ancestral patten for all the hominins, from which modern humans would have evolved. This break down from the ancestral pattern could be related to the selective pressures to bipedalism. From an evolutionary point view, these morphological changes in the human lineage did not occur in all the cervical vertebrae at the same time. Indeed, our results indicate there has been a relative stasis in the most caudal cervical vertebrae (i.e., C6-C7), whereas those located in a more cranial position evolved earlier and show a more derived morphology.Similarly, the results from the analyses regarding the relationship between the cranium and the cervical region, also reveal a distinct pattern of cranium-cervical integration for modern humans. The scarce Neandertal evidence seems to be roughly consistent with the distinct pattern showed by modern humans, which suggests a shared pattern for the (late) genus Homo. Finally, the last work, based on the study of the whole pre-sacral spine, shows that the thoracic vertebrae are internally the most integrated from the entire pre-sacral vertebral column. The high level of integration in the thoracic region decreases towards the most peripherally located vertebrae (i.e., C1-L5), where integration reaches its lowest values. The high integration in this region could have limited the ability of these vertebrae to respond to selection demands, probably caused by the functional constraints produced by their articulation with the thorax. In contrast, lumbar vertebrae are the most evolvable, and this could be due to functional factors related to the bipedal locomotion mode shown by modern humans, but also to developmental and genetic factors. We suggest that this evolutive pattern in the lumbar region in modern humans could also be present in all mammals. This hypothesis is based on the large variability shown by mammals in their locomotion modes, also in the high variation in the number of lumbar vertebrae, and in the ancestral body plane they shared due to the expression of the Hox genes

As vértebras cervicais vêm sendo cada vez mais empregadas para a análise de maturação óssea em Ortodontia e Ortopedia Funcional dos Maxilares. Visto que as mudanças que ocorrem nessas estruturas são sutis, comparou-se, por meio de medidas, sete razões obtidas nas vértebras cervicais C2, C3 e C4 em radiografias cefalométricas laterais entre as fases da curva de crescimento puberal de 95 pacientes do sexo feminino e 136 do masculino. Os resultados demonstraram que a razão 1 (C2Conc/C2PI-C2AI) difere estatisticamente entre os grupos A/B e C/D nos indivíduos do sexo masculino e entre B/C e D/E nos do feminino; a razão 2 (C3Conc/C3PI-C3AI) difere estatisticamente entre os grupos A/B/C/D nos indivíduos do sexo masculino e entre B/C e D/E nos do feminino; a razão 3 (C4Conc/C4PI-C4AI) difere estatisticamente entre os grupos B/C/D nos indivíduos do sexo masculino e entre B/C e D/E nos do feminino; a razão 4 (C3AS-C3AI/C3PS-C3PI) difere estatisticamente entre os grupos B/C nos indivíduos do sexo masculino e entre B/C/E nos do feminino; a razão 5 (Altura do corpo de C3/Comprimento do corpo de C3) difere estatisticamente entre os grupos A/C/D/E nos indivíduos do sexo masculino e entre A/C e D/E nos do feminino; a razão 6 (C4ASC4AI/ C4PS-C4PI) difere estatisticamente entre os grupos B/C nos indivíduos do sexo masculino e entre os grupos B/C/D nos do feminino; e a razão 7 (Altura do corpo de C4/Comprimento do corpo de C4) difere estatisticamente entre os grupos C/D nos indivíduos do sexo masculino e entre A/C/D nos do feminino.
The cervical vertebrae have been employed on the assessment of the bone maturation stage on the last years. Since the changes on these structures are subtle, seven ratios obtained from measurements on lateral cephalometric radiographs of the second, third and fourth cervical vertebrae were compared among the phases of the pubertal growth curve of 95 male and 136 female patients. The results demonstrated that ratio 1 (C2Conc/C2PI-C2AI) differs statistically between groups A/B and C/D on male subjects and between groups B/C and D/E on female subjects; ratio 2 (C3Conc/C3PI-C3AI) is statistically different among groups A/B/C/D on males and between B/C and D/E on females; ratio 3 (C4Conc/C4PI-C4AI) differs statistically among groups B/C/D on males and between B/C and D/E on females; ratio 4 (C3AS-C3AI/C3PS-C3PI) is statistically different between groups B/C on males and among B/C/E on females; ratio 5 (Height of the body of C3/Length of the body of C3) differs statistically among groups A/C/D/E on males and between A/C and D/E on females; ratio 6 (C4AS-C4AI/C4PS-C4PI) differs statistically between groups B/C on male subjects and among groups B/C/D on females; and ratio 7 (Height of the body of C4/Length of the body of C4) differs statistically between groups C/D on males and among A/C/D on females.

Full textThe objective of this study was to examine the relationship between external markers typically used in external motion capturing devices and the true vertebral kinematics in the cervical spine. Twenty one healthy subjects were subjected to low dosage X-rays in five different positions, while radio opaque markers were attached to the skin at each vertebral level. Distance and angle parameters were constructed for vertebral prediction from skin surface markers. The causes of variation in these parameters were identified by investigating the correlations of these parameters with anthropometrical variables. Strong correlations of the parameters were observed in flexion, but in extension, especially full extension, the correlations were poor to insignificant. In neutral, half flexion, and full flexion it is possible to predict the vertebral position from surface markers by using the parameters and anthropometrical variables. In half extension this prediction is less accurate and in full extension alternative methods should be investigated for external motion capturing.

Full textPercutaneous vertebroplasty (PV) consists of an injection of polymethylmethacrylate (PMMA) into the vertebral body for pain relief and spinal stabilization, however reports of PV in the cervical spine (CPV) are scarce in the literature. To evaluate the effectiveness and security of CPV, we evaluated 75 patients (mean age, 51.3 years) who underwent CPV (n=101) for malignancies (n=69) and vertebral hemangiomas (n=6) between January 1994 and October 2007. CPV was performed via an antero-lateral approach, using fluoroscopic guidance. Pain intensity was scored with a scale ranging from 0 to 10. Follow-up (mean time of 8.8 months) was avaible in 57 (76 %) patients: 48 of them had CPV indicated for pain control and nine for spinal stabilization. Data were analysed by means of univariate and multivariate analysis. Pain improvement was observed in 37 (77.1%) out of 48 followed patients and was correlated in multivariate analysis with cement volume (P=0.011) and with vertebral filling (P=0.007). Spinal stabilization was observed in 55 (96.5%) of 57 followed patients and was related with none of the evaluated variables. The ROC curve identified the vertebral filling as a good predictor of pain improvement (P=0.008). The best cut-off point to discriminate pain improvement was 50% of vertebral filling (78.0% sensitivity and 62.5% specificity). In 83 (82.2%) of the 101 treated vertebral levels, at least one type of PMMA leakage was found. None of the evaluated factors were related significantly to PMMA leakage. Clinical complications were detected in 13 (17.3%) patients: local complications in 10 (13.3%) patients and systemic clinical complications in three (4.0%) patients. Posterior wall disruption (P=0.026) and transverse venous PMMA leakage (P=0.023) were significantly associated with clinical complications. Long-term morbidity and mortality rate was 1.3% (one patient) and 1.3% (one patient). CPV is a safe and efficacious procedure, but the potential for local and systemic complications must be considered. Cement volume and vertebral filling were associated with pain improvement but not with spinal stability. Vertebral filling has a good performance to predict pain improvement and a cut-off of 50% of vertebral filing obtained the best compromise between sensitivity and specificity to discriminate pain improvement

The purpose of this study was to determine the morphology of the third and fourth cervical vertebrae which represent the prepeak, peak and postpeak stages of statural growth, previously defined by ossification centers of the thumb in hand-wrist or thumb periapical radiographs. The sample was comprised of 120 lateral cephalometric radiographs of 106 patients from the Orthodontics Clinic of the School of Dentistry of Araçatuba - UNESP and from PROFIS /Hospital for Rehabilitation of Craniofacial Anomalies-USP. All patients had hand-wrist or corresponding thumb periapical radiographs available. The lateral radiographs were divided into three groups of 40 radiographs according to the prepeak, peak and postpeak maturational stages, defined by the radiographic image of the thumb. The morphology of the third and fourth cervical vertebrae was determined by two calibrated examiners in two different times. The findings show that the horizontal, rectangular-shaped vertebra with straight lower border represented the prepeak stage, regardless of the analyzed vertebra. The horizontal, rectangular-shaped vertebra with curved lower border, mainly if found in C4, or the square-shaped vertebra with straight lower border was typical of the growth peak. The square-shaped or, mainly, the rectangular-shaped vertebra with curved lower border determined the postpeak stage of adolescent growth spurt.

Full textThe evaluation of the curvature of the cervical spine carried out by chiropractors, physical therapists and orthopedists is important for obtaining a desired clinical result, being the X-ray examination the gold standard and the most widely used in clinical practice. However, because of its invasive nature is considered unsuitable for repeated use to monitor postural treatments, in addition difficulties in portability of the equipment, the time required to obtain and read the radiographic image and costs related to the examination. In this sense, researchers have investigated less invasive, practical and low cost methods to diagnose changes in curvature of the spine. However, the choice of a tool should be based on scientific parameters such as validity, reproducibility and repeatability. The flexicurve already has these psychometric properties with respect to the thoracic and lumbar spine, but lacks information on its use in the cervical spine. This dissertation was divided into two studies: Study 1 - We performed a systematic review in order to investigate the non-invasive methods available to evaluate the cervical curvature in the sagittal plane. The methodology used in this study followed the recommendations proposed by the Cochrane Collaboration. Sixteen articles were included for review from the selection criteria. In assessing the methodological quality thirteen of the sixteen studies were considered high quality. A total of five methods to assess the lordosis of the cervical spine were found in review articles: (1) Photogrammetry; (2) Visual assessment; (3) Flexicurve; (4) 3D scanning system; (5) 3D ultrasound posture system. The results of this systematic review showed that the photogrammetry showed the best results of reproducibility, however, lack concurrent validation. Visual assessment showed not be reproducible and also lacks concurrent validation. The flexicurve demonstrated controversial results for reproducibility and the need for more studies with different anatomical sites for evaluation of the concurrent validity. And both systems that evaluate the cervical spine in 3D require further study, and the fact they are more expensive and complex for applicability. Study 2 - In the validation study, the objectives were: (1) identify the concurrent validity of the flexicurve instrument from the concordance between the results of the examination of X-rays and flexicurve; (2) to verify the reproducibility intra and inter evaluator of flexicurve instrument; and (3) identify the diagnostic capacity of the measure provided by flexicurve instrument. The sample consisted of 118 adult volunteers individuals of both sexes divided into two groups : (1) VAL group (n=55) participated in the concurrent validation phase; (2) REP group (n=58) participated in the evaluation phase of the reproducibility of flexicurve. For analysis purposes, the VAL and REP groups were divided into sub-groups by body mass index (BMI). In statistical analysis, for concurrent validity were used: Correlation Test Product-Moment Pearson, paired t test, RMS error and graphical analysis of Bland and Altman. For reproducibility: intraclass correlation coefficient (ICC), standard error of measurement (SEM) and the minimum detectable change (MDC). (<0,05). The REP group presented results of excellent reproducibility intra evaluator (ICC= 0,771; p<0,001; SEM=4,40; MDC=8,60) and inter evaluator (ICC=0,775; p<0,001; SEM=4,30; MDC=8,50), this result being maintained for sub-groups "low weight" and "overweight", while in "healthy" subgroup reproducibility of the result was considered moderate. Regarding the concurrent validation, the VAL group showed high correlation between the angles of flexicurve and Cobb angles (r=0,570; p<0,001; RMS Error=9,83º). Still, the sub-group “underweight” showed practically perfect correlation (r=0,926; p<0,001; RMS error=5,66º), the “healthy” sub-group high correlation (r=0,575; p<0,001; RMS error<9,01º), and the sub- group “overweight” showed no correlation (r=0,069; p=0,832). As for the diagnostic capacity, flexicurve had a sensitivity of 59% and specificity of 44% .In conclusion the flexicurve showed a reproducible tool to be used by the same evaluator as well as by different evaluators, and also proved a valid tool to assess curvature of the cervical spine in the sagittal plane in adults classified by BMI underweight and healthy.

Full textLa première partie de ce travail a comme objectif fondamental de déterminer la cinématique 3D inter-segmentaire de la colonne cervicale, lors de la rotation axiale maximale de la tête. Les valeurs déterminées pour tous les paramètres cinématiques 3D vont nous servir comme base de données de référence.
Dans la deuxième partie, nous souhaitons contribuer à une meilleure compréhension du rôle des ligaments alaires lors de la rotation axiale. Pour cela, nous avons déterminé la cinématique 3D de l’os occipital par rapport à l’axis. Même s’il est inhabituel d’ignorer l’atlas, il nous a semblé plus juste de considérer les segments osseux qui livrent les principales insertions des ligaments alaires. La biomécanique de ces ligaments dépend des mouvements de l’os occipital par rapport à l’axis.
La troisième partie est orientée vers l’objectif principal de la thèse qui vise à déterminer les amplitudes articulaires inter-segmentaires lors de la position pré-manipulative de la colonne cervicale. Cette étude va nous permettre de comparer les amplitudes atteintes lors de la mise en position pré-manipulative avec celles des mouvements physiologiques.
La dernière partie a pour objectif principal de déterminer la longueur du trajet de l’artère vertébrale en position neutre, et ensuite de comparer la variation de longueur du trajet de l’artère vertébrale entre la position en rotation axiale maximale de la tête d’une part, et la position pré-manipulative d’autre part, donc lors de l’application d’une technique manipulative à composantes multiples telle qu’utilisée régulièrement en ostéopathie.
En comparant la position pré-manipulative à la rotation physiologique, les résultats les plus importants de ce travail sont :(1) les amplitudes segmentaires sont inférieures pour la position pré-manipulative et (2) l’artère vertébrale est moins allongée lors de cette mise en position que lors de la rotation physiologique. Ces deux faits, jusque-là inédits, sont importants en clinique ostéopathique courante et montrent l’importance d’un choix judicieux de la technique manipulative et de son exécution.

Full textThe purpose of this study was to evaluate the possible relationship between the stages of skeletal maturation analyzed by means of hand-wrist radiography and cervical vertebrae in lateral cephalograms, from individuals with mean age of 13 years and 6 months, S.D. 2 years and 3 months (ranging from 8 years and 6 months to 16 years and 11 months). The sample was composed by 209 radiography sets (hand-wrist radiography and lateral cephalograms) taken in the same date for each individual. Two investigators, properly trained and calibrated, classified all the hand-wrist radiography relating them to the skeletal maturation according to Helm et al. The cervical vertebrae evaluation was performed in lateral cephalograms by means of the O'Reilly and Yaniello and Baccetti, Franchi and McNamara method. Considering the classification of Helm et al as gold standard, Spearman test correlation was applied to verify relationship with the two methods that evaluate the cervical vertebrae. The results indicated that there was strong correlation among the methods of evaluation of the cervical vertebrae and hand-wrist radiography (Rs =0,906 for O'Reilly and Yaniello and Helm et al and Rs = 0,889 for Baccetti et al and Helm et al, for all p <0,001). The descriptive statistical analysis indicated that there was larger number of concordant occurrences in the identification of the onset and maximum peak of the adolescent growth spurt. Based on these results, it can be concluded that the evaluation of the skeletal maturation by means of the cervical vertebrae method can offer reliability only for the identification of the onset and peak of adolescent growth spurt. Thus, is still indispensable to continue using the hand-wrist radiography when it is necessary the identification of some potential remaining growth.

Full textThe study of growth and development is essential for orthodontics, because each child has a unique pattern. In the presence of systemic diseases such as congenital heart disease, a more detailed examination must be made, since they may alter their growth and development. One of the methods used for this evaluation is bone ossification analysis of the hand and wrist region. However, changes in size and shape of the cervical vertebrae have been widely used in recent decades because it is performed in lateral cephalometric radiographs, routinely used in orthodontic diagnosis. Initially, our objectives were to assess the correlation between the methods for obtaining bone age and skeletal maturation stages using the indicators present in the hand and wrist region and in the cervical vertebrae in a group of children with and without heart disease. Based on the positive and significant correlation, the cervical vertebrae method was chosen to compare bone age, the difference between bone age and chronological and skeletal maturation stages between children with and without heart disease. The sample comprised 120 children aged 4.83 to 14.66 years, that attended the Pediatric Clinic of Pedro Ernesto University Hospital. Among these, 73 presented cyanotic congenital heart disease and 47 had no heart disease and were only on follow-up, with a mean age of 9.3 and 8.9 years respectively. The bone age and skeletal maturation were verified by lateral cephalometric radiographs and hand-wrist radiographs. The bone age determination was performed by the Mito et al. method on lateral cephalometric radiographs and by the Greulich and Pyle method on hand-wrist radiographs. The skeletal maturation stages were obtained by the Hassel and Farman method on lateral cephalometric radiographs and by the Singer method on hand-wrist radiographs. The correlation between the methods for obtaining bone age and skeletal maturation stages showed a positive and significant results, both for the heart disease group with r = 0.478 (p <0.001) for bone age and r = 0.616 (p <0.001) for skeletal maturation stages, and for non-heart disease group with r = 0.366 (p = 0.024) for bone age and r = 0.613 (p <0.001) for the skeletal maturation stages. The bone age did not differ significantly between groups (p = 0.394). The difference between chronological age and bone age showed no significant difference in both heart disease group (p = 0.418) and for non-heart disease group (p = 0.143). No significant differences were found between groups when the amount of children who had delayed bone age relative to chronological age (p = 0.395) were assessed. The same was found when males (p = 0.060) and females (p = 0.313) were evaluated. The sample distribution through skeletal maturation stages showed no significant differences between groups (p = 0.447). The results of this study suggest that congenital heart disease, in the evaluated age, does not alter skeletal maturation pattern examined by the cervical vertebrae method.

Full textMotivated by the challenges associated with demonstrating the cervicothoracic junction, a study was conducted at Pelonomi Regional Hospital from May 2006 to June 2007. In this study, two projections of the cervicothoracic junction were done, with the only difference between them being the orientation of the arms. One projection was done using the swimmer’s projection and the other using an adaptation of the swimmer’s projection where the orientation of the arms was reversed. The sample, consisting of 45 patients, was referred from the emergency department and wards. Most of the patients (95.5%) were examined using a computed radiography system providing digital images that were printed using a laser film printer. Other patients were examined using conventional film/screen systems. The objectives of this study were to compare the two imaging techniques with reference to diagnostic quality of the projections, diagnosis of pathology and repeat rate. Radiographers obtained the two projections of the cervical spine; the researcher collected the images and distributed these to three participating radiologists on a rotational basis. The radiologists evaluated the films using a set of criteria; a biostatistician analysed the results of these evaluations. In all the criteria of image quality the swimmer’s projection showed better results. There were also, however, instances where the adapted swimmer’s had better results. The differences in percentages were not significant enough to show any statistical difference between the resultant images of the two techniques. No valid deduction could be made in relation to the demonstration of pathology due to variable instances of pathology evaluated by the radiologists. The repeat rate of the adapted swimmer’s projection compared well with the swimmer’s projection. Though the swimmer’s projection had better results for most of the criteria used in this study, no unequivocal, statistically significant evidence of it demonstrating C7-T1 better could be found. What was evident was the validity of the adapted swimmer’s projection as an alternative under certain conditions. Knowing that there is an alternative method to visualising the C7- T1 junction could be beneficial not only to radiography, but also to our patients. In cases where the swimmer’s projection is not possible due to extremity injuries, an alternative arm orientation can be useful. The alternative can also address the problem regarding multiple repeats of the swimmer’s projection.

Full textENGLISH ABSTRACT: Neck pain is a common phenomenon that occurs in a large percentage of the population every day. While many occurrences are not deemed critical such as those from muscle strain which can be treated with rest and pain medication, others due to sports injuries, whiplash from car accidents, bad posture or degeneration of the intervertebral disc can be quite severe. In extreme cases failure of the vertebra(e) or the intervertebral disc requires surgery and possibly the use of cervical implants. Where intervertebral discs fail due to herniation or Degenerative Disc Disease (DDD), Anterior Cervical Discectomy and Fusion (ACDF) is a common surgical method used to remove the a ected disc and replace it with a cervical cage implant. These implants are designed to restore the height between the vertebrae, allowing bone from both vertebrae to grow through them and mineralise. Additive Manufacturing (AM) technologies can produce parts with complex geometries not possible using conventional manufacturing methods. This design freedom, coupled with CT scans of a patient, allow for tailoring an implant to the speci c anatomy of the a ected vertebrae using CAD software. Such an approach must be regulated and shown to be technically and commercially feasible before it can be implemented in industry. This study sought to develop a framework for manufacturing customized cervical cage implants using additive manufacturing. The e cacy of customization to reduce the risk of subsidence was investigated by means of non-destructive and destructive mechanical testing on six cadaver specimens, using readily available PEEK cage implants as a benchmark. The results showed that the customized implant was comparable to the PEEK, with no statistically signi cant di erence between the two. In extreme cases, where PEEK implants cannot be used, customized implants could be a suitable alternative to reduce the risk of subsidence. A manufacturing cost analysis was conducted to determine economic feasibility. The estimated cost and selling price of the customized implants under various utilization scenarios and mark-ups was compared to readily available PEEK implants. The estimated selling prices of the customized implants compared favourably to the PEEK verifying the economic viability of using AM.
AFRIKAANSE OPSOMMING: Nek pyn is 'n algemene verskynsel wat daagliks na tevore kom in die bevolking. Baie gevalle word nie as krities geklasi seer nie soos byvoorbeeld spier pyn wat behandel kan word deur genoegsame rus en pyn medikasie. Pyn wat deur sportbeserings, sweepslag beserings 'whiplash' tydens motor ongelukke, verkeerde postuur, of deur slytasie van 'n intervertebrale skyf veroorsaak is, word dikwels as ernstig geklasi seer. In ekstreme gevalle waar die werwel(s) of die inervertebrale skyf(we) faal, sal chirurgie en servikale inplantate moontlik nodig wees. Waneer intervertebrale skywe faal weens herniatie of Degeneratiewe Skyf Siekte (DDD) kan 'n algemene chirurgiese metode, Anterieure Servikale Discectomie en Fusie (ACDF), gebruik word om die gea ekteerde skyf te verwyder en dit te vervang met 'n servikale samesmelting implantaat. Hierdie implantate herstel die hoogte tussen rugwerwels en is ontwerp sodat die been deur dit kan groei en mineraliseer. Komplekse geometrieë kan vervaardig word deur toevoegingsvervaardiging (AM) tegnologieë. Die ontwerp vryheid, gepaard met CT-skanderings en CAD-sagteware stel mens in staat om die geometrie van die implantaat aan te pas tot die spese eke anatomie van die gea ekteerde vertebra. So 'n benadering moet gereguleer word en eers tegnies en kommersieel uitvoerbaar bewys word voordat dit in die bedryf geïmplementeer kan word. Hierdie studie poog verder om 'n raamwerk vir die vervaardiging van persoonlike servikale implantate deur middel van toevoegingsvervaardiging te ontwikkel. Die doeltre endheid van persoonlike implantate om te verhoed dat die chirurg die eind-plaat beskadig, en sodoende die risiko van insakking te verminder, is ondersoek deur middel van meganiese toetse op ses kadawer monsters. Hierdie toetse is gedoen met behulp van geredelik beskikbaar PEEK servikale implantate as 'n maatstaf. Die resultate het getoon dat die persoonlike- en PEEK implantate vergelykbaar is. In moontlike gevalle waar PEEK implantate nie geskik sou wees nie, kan persoonlike implantate 'n alternatiewe opsie wees om die risiko van insakking te verminder.

Resumo: As vértebras cervicais vêm sendo cada vez mais empregadas para a análise de maturação óssea em Ortodontia e Ortopedia Funcional dos Maxilares. Visto que as mudanças que ocorrem nessas estruturas são sutis, comparou-se, por meio de medidas, sete razões obtidas nas vértebras cervicais C2, C3 e C4 em radiografias cefalométricas laterais entre as fases da curva de crescimento puberal de 95 pacientes do sexo feminino e 136 do masculino. Os resultados demonstraram que a razão 1 (C2Conc/C2PI-C2AI) difere estatisticamente entre os grupos A/B e C/D nos indivíduos do sexo masculino e entre B/C e D/E nos do feminino; a razão 2 (C3Conc/C3PI-C3AI) difere estatisticamente entre os grupos A/B/C/D nos indivíduos do sexo masculino e entre B/C e D/E nos do feminino; a razão 3 (C4Conc/C4PI-C4AI) difere estatisticamente entre os grupos B/C/D nos indivíduos do sexo masculino e entre B/C e D/E nos do feminino; a razão 4 (C3AS-C3AI/C3PS-C3PI) difere estatisticamente entre os grupos B/C nos indivíduos do sexo masculino e entre B/C/E nos do feminino; a razão 5 (Altura do corpo de C3/Comprimento do corpo de C3) difere estatisticamente entre os grupos A/C/D/E nos indivíduos do sexo masculino e entre A/C e D/E nos do feminino; a razão 6 (C4ASC4AI/ C4PS-C4PI) difere estatisticamente entre os grupos B/C nos indivíduos do sexo masculino e entre os grupos B/C/D nos do feminino; e a razão 7 (Altura do corpo de C4/Comprimento do corpo de C4) difere estatisticamente entre os grupos C/D nos indivíduos do sexo masculino e entre A/C/D nos do feminino.
Abstract: The cervical vertebrae have been employed on the assessment of the bone maturation stage on the last years. Since the changes on these structures are subtle, seven ratios obtained from measurements on lateral cephalometric radiographs of the second, third and fourth cervical vertebrae were compared among the phases of the pubertal growth curve of 95 male and 136 female patients. The results demonstrated that ratio 1 (C2Conc/C2PI-C2AI) differs statistically between groups A/B and C/D on male subjects and between groups B/C and D/E on female subjects; ratio 2 (C3Conc/C3PI-C3AI) is statistically different among groups A/B/C/D on males and between B/C and D/E on females; ratio 3 (C4Conc/C4PI-C4AI) differs statistically among groups B/C/D on males and between B/C and D/E on females; ratio 4 (C3AS-C3AI/C3PS-C3PI) is statistically different between groups B/C on males and among B/C/E on females; ratio 5 (Height of the body of C3/Length of the body of C3) differs statistically among groups A/C/D/E on males and between A/C and D/E on females; ratio 6 (C4AS-C4AI/C4PS-C4PI) differs statistically between groups B/C on male subjects and among groups B/C/D on females; and ratio 7 (Height of the body of C4/Length of the body of C4) differs statistically between groups C/D on males and among A/C/D on females.

Full textThis study aimed to evaluate the growth phase in a sample of 49 patients, with ages ranging from 9 to 15 years old, observing the cervical vertebrae on lateral radiographs taken in natural head position (NHP) and positioning errors, with head inclination up to 15° (NHP-High) and 15° down (NHP-Low), to define how important this is in the accuracy assessment phase of growth. The weighted kappa test showed a substantial degree of agreement between NHP and NHP High and between NHP and NHP-Low. Since the nonparametric test of wilcoxon (p <0.05) showed statistically significant difference between these comparisons. Thus, the NHP showed to be more reliable in assessing the cervical vertebrae maturation (CVM), furthermore the radiographs with positioning accuracy evaluated did not show statistically significant with the PNC.(AU)

O teste kappa ponderado mostrou um grau de concordância substancial entre PNC e PNC-Alta e entre PNC e PNC-Baixa. Já o teste não paramétrico de wilcoxon (p<0,05) mostrou diferença estatisticamente significante entre essas comparações. Desta forma, a PNC demonstrou ser mais confiável na avaliação do Índice de Maturação das Vértebras Cervicais (IMVC), porém as telerradiografias com erro de posicionamento avaliadas não tiveram um grau de discordância que indicasse sua não utilização na clínica para predição de crescimento.(AU)

Full textCraniofacial growth characteristics of individuals with Class II malocclusion at the stage of growth are of intense interest os Orthodontists for this malocclusion represents a high percentage of cases where treatment in clinics. The purpose of this study was to compare the craniofacial growth changes through 148 (78 males and 70 females) lateral cephalograms of untreated subjects with Class II Division 1 malocclusion, at a mean age of 10,03 years, with those lateral cephalograms of 60 (30 males ans 30 females) subjects with normal occlusion, at a mean age of 10 years, divided by stages of development (Initiation, Acceleration and Transition) as defined by a biological indicator of cervical vertebrae skeletal maturity (HASSEL; FARMAN 1995). Cephalometric measurements in Class II and Normal Occlusion evaluated was SNA, A-Nperp, Co-A, SNB, P-Nperp, Co-Gn, Co-Go, Go-Gn, ANB, SN.GoGn, FMA, NS.Gn, BaN.PtGn, ENA-Me and NS.Ba. Statistical comparision of the growth changes in the study groups, stages os development and gender were performed with independent t test. Evaluating the Class II group, mens presented Co-A, Co-Gn, Go-Gn and ENA-Me larger at stage I and at stage A accompanied by greater FMA; in stage T, just Co-Gn and ENA-Me were the largest group of Class II of male gender. Evaluating the Normal Occlusion group, mens presented FMA, NSGn larger at stage I and at stage A, accompanied by greater Co-A, SNB, P-Nperp, Co-Gn and ENA-Me, while the female gender has greater value of NSBa; at stage T, only Co-Go was statistically higher in mens gender. In the comparision between the groups of female gender and stage I, the group Class II presented statistical significance for the variables A-Nperp, Co-Go, ANB, SN.GoGn, NS.Gn, BaN.PtGn, ENA-Me e NSBA; at stage A, Co-Go, ANB, NS.Gn, ENA-Me and NSBa were the largest group of Class II that had less BaN.PtGn; at stage T, just Co-Go and BaN.PtGn remained significant for the group Class II. In the comparision between the groups of male gender and stage I, the group Class II presented statistical significance for the variables SNB, Co-Gn, Co-Go, ANB, ENA-Me and NSBa; at stage A, just SNB, ANB and BaNPtGn were significant, and remained in stage T. Evaluating the female gender groups in phase IT, the variables A-Nperp and Co-Go were the largest group of Class II, accompanied by poor relations between the bases described by ANB, more vertical growth pattern (SN.GoGn, NS.Gn, BaN.PtGn, ENA-Me) and greater NSBa. In the comparision between the groups of male gender in phase IT, the group Class II presented greater SNB, ANB, vertical craniofacial growth trend (BaN.PtGn) and greater deflexion at the base of the skull (NSBa).

Full textThe age estimation in living subjects is a challenge with significant importance in civil and criminal areas. The study of human body structures to estimate the chronological age is guided by the evaluation of events which happens during the processes of growth and development, since they have a constant and logic sequence. The worldwide literature has suggested a multifactorial approach to age estimation in living subjects which is the evaluation of development of more than one anatomical location. In this sense, the objectives of the first phase of the study consisted in validate the age estimation method through oro-cervical radiographic indexes in Brazilians and identify the relationship between real age and estimated age with application of radiographic indexes. The second phase of study aimed to verify the effectiveness of age estimation equations proposed by Chaillet and Demirjian (2004) through dental exams, and evaluated Caldas et al. (2007a) age estimation equations using cervical vertebrae. The last aim was to develop new equations for estimating the real age associating dental data and cervical measures of previous methods. The sample comprised panoramic radiographs and teleradiography belonging to 510 subjects, aged 08 to 24.9 years old. During the first phase of the research, age estimation methods were applied by assessing the development of seven mandibular teeth, cervical vertebrae and third molars. Then, the techniques used previously have been combined by radiographic indexes: the Oro-Cervical Radiographic Simplified Score (OCRSS) and Oro-Cervical Radiographic Simplified Score without Wisdom Teeth (OCRSSWWT). During the second phase, evaluated the dental maturation, assigned the score to each tooth and the real age was estimated by regression equations of Chaillet and Demirjian (2004). Regarding the cervical vertebrae, measurements were made of vertebral bodies and the values were used in formulas proposed by Caldas et al. (2007a). The findings of study show that between radiographic scores, the OCRSS presented a positive rate of 67.4% and a moderate relationship with chronological age with a coefficient of determination (R2) equivalent to 0.64; for EROCSSTM the hit rate was 70.8% and R2 of 0.62. Chaillet and Demirjian\'s technique was applied for dental age estimation, which showed an average error of 1.3 years and the method of Caldas et al. (2007a) was applied for cervical vertebrae age estimation with an average error of 1.9 years. Dental variables and measurements of cervical vertebrae were associated and new regression equations were developed for Brazilians, and the average error of equations developed in the study was 1.0 year. Finally, the method with radiographic indexes was easy to perform after adequate training, reliable and can be used in forensic practice. In addition, the use of new equations presented in this study is recommended because associating cervical vertebrae data with dental development allowed age estimates with greater accuracy.
