Повний текст джерелаIntroduction In clinical physiotherapy, there is a growing importance for the accuracy and reliability of assessment and outcome measures. The purpose of this study is to develop a valid outcome measure for orthopaedic trauma inpatients. Item generation was done by conducting a systematic review of published functional outcome measures and patients' interview. Item reduction was conducted by using a panel of physiotherapists and patients. Objectives The overall study objectives were: 1) To determine if a functional outcome measurement scale for trauma inpatients exists and has been published; 2) To generate functional items for the construction of a new outcome measurement tool for trauma inpatients; 3) To construct a new outcome measurement tool for trauma inpatients and assess elements of validity and reliability (face and content validity, response to change, internal consistency and floor and ceiling effects) of the new developed outcome measure. Methodology Convenience sampling was applied to collect data from 35 trauma inpatients in trauma wards at Rashid Hospital in Dubai, UAE. 88% of the trauma inpatients were male (total sample n= 100), mean age =34.75, and the standard deviation = 14.46. 21 functional activity items were generated from the collated results of the patient interviews. Internal consistency reliability, responsiveness and floor and ceiling effect were assessed. Data analysis was conducted using Statistica Version 7. Results The final number of functional activity items included in the newly developed Functional Scale outcome measure was 29 activity items relevant for trauma inpatients. A Cronbach's alpha ranged between 0.76 and 0.97. The lowest alpha result was for the 'ADL' activities at follow-up (0.76). The highest alpha result was for 'out of bed' activity at admission and discharge (0.97). The response to change of the Functional Scale for trauma inpatients over time results illustrates that there was a significant difference in the mean scores over three administrations of 'Bed', 'Out of bed' and 'ADL' activity items of Functional Scale for trauma inpatients (p=O.OOOO). In general, there was no significant floor and ceiling effects at admission or discharge for 'bed', 'out of bed' and 'ADL' activities, except there was a floor effect noted at discharge for 'bed' activities and 'ADL' activities, and a ceiling effect noted at admission for 'out of bed activities' only. Discussion and Conclusion The newly developed Functional Scale outcome measurement for trauma inpatients has been shown to be internally consistent and appears to be valid with respect to response to change in this sample of trauma inpatients. The results of this study thus suggest that the Functional Scale for trauma inpatients may be an appropriate tool when the goal is the assessment of change in disability functions in trauma inpatients, although further psychometric testing may be required.

In recent years, people have paid attention on the service quality of healthcare providers under the competitive medical service industry. Patient waiting time is a critical factor that affects patients’ satisfaction. Based on Taoyuan Armed Forces General Hospital (TYAFGH) survey questionnaire, it showed that the long waiting time is the major problem of patient dissatisfaction. The average walk-in patient waiting time is approximately 2 hours in trauma team of orthopaedic surgery department. The hospital has a mixed registration type which accepts for both walk-in and scheduled patients. The reason of long waiting time is probably caused by the uncertain number of walk-in patients, or patient arrival time. In order to improve patient satisfaction, this research used a computer simulation approach to simulate all consultation sections of two physicians’ outpatient in trauma team of orthopaedics surgery department in TYAFGH. In the beginning, we analyzed the real data of two physicians during two months to build a valid simulation model. Then, this research applied three main patient scheduling scenarios. The first scenario made adjustments for proportion of walk-in and scheduled patients. The second scenario applied different policies for late patients and then adjusted late patient proportion. Third, this research applied various sequences for walk-in and scheduled patients. Finally, we did sensitivity analysis to find out the influential factor for reducing patient waiting time. The simulation results showed that the improvement of walk-in patient waiting time was average 53% in the first scenario and 33% in the third scenario. The second scenario has not shown effective improvement. Thus, in conclusion, through testing three scenarios, we could find out the adjustment of walk-ins proportion is the best way to improve patient waiting time.

In recent years, common clinical cases of bone fractures, bone defect, and other trauma cases have been made custom implants. Implantation simulation through pre-operative digitalization, can more closely construct a customized medical implant model that meets the needs of patients. With the multi-layer manufacturing technology, it is also a 3D printing technology that can quickly and in accordance with various special models to establish the medical implants required by patients. In order to pursue a better osseointegration effect between the implant and the human bone tissue, the implant is designed with a hole in the popular application. Produces a bone sponge state similar to the internal bone mass, providing a good bone cell growth environment between the implant and the bone mass, and efficiently traversing and adhering the bone cell tissue to the implant. The implant and the bone are tightly joined to form a high-strength structural osseointegration, which also reduces the risk of secondary injury caused by separation and breakage between the implant and the bone. In this paper, we will study traumatic cases such as bone fragments and bone defects that are common in clinical practice. 3D reconstruction of CT(Computed Tomography) images will be carried out through professional 3D medical image reconstruction software system. Symmetrical relationship through the left and right bones of the human body. In 3D visualization of virtual 3D space for 3D model movement, mirroring, and fallback fitting calculation. 3D bone block reduction simulation before surgery from the reference healthy bone block. And after the reduction, such as the formation of a bone defect case, the spatial structure model logic gate is used to calculate the bone implant model that needs to fill the defect. And through the calculus combination of the basic cubic crystal model and several different cubic structures, an array of porous mesh structure models is generated. Compare the different bone mineral density of human bone tissue, and combine the model and the implant with the model logic gate. Generating a medical implant with a porous structural mesh inside. Establish a customized implant model with 3D printing process. From the pre-operative bone trauma reduction simulation to the planning and establishment of the implant model, and the rapid creation of the pore structure grid inside the implant model.

Повний текст джерелаContinued tobacco smoking after orthopaedic trauma surgery can have a negative impact on health outcomes. Despite this, limited research has been conducted with the orthopaedic trauma population to determine current rates of care, and interest in receiving help to quit during hospital admission. Further, rates of current tobacco smoking among the orthopaedic trauma population has previously been found to be high, indicating a need to address rates of smoking in this population. The implementation of hospital smoke-free policy in Australia mandates the provision of smoking cessation care for all patients, and that the hospital admission may provide an ideal time when individuals are receptive to health messages. Despite this, implementation of hospital smoke-free policy has been found to be low, with care previously found to be sub-optimal. The aim of this thesis was to explore the current provision of care, the barriers faced by staff, and possible factors which may help address hospital smoke-free policy. The development and pilot testing of an online smoking cessation program designed specifically for orthopaedic trauma patients is described. Competing priorities and comorbid conditions in the lives of orthopaedic trauma patients were identified as complicating smoking cessation treatment and are discussed.

Повний текст джерелаThe introduction of imaging techniques in 1970 is one of the most relevant historical milestones in modern medicine. Medical imaging techniques have dramatically changed our understanding of the Human anatomy and physiology. The ability to non-invasively extract visual information allowed, not only the three-dimensional representation of the internal organs and musculo-skeletal system, but also the simulation of surgical procedures, the execution of computer aided surgeries, the development of more accurate biomechanical models, the development of custom-made implants, among others. The combination of the most advanced medical imaging systems with the most advanced CAD and CAM techniques, may allow the development of custom-made implants that meet patient-speci c traits. The geometrical and functional optimization of these devices may increase implant life-expectancy, especially in patients with marked deviations from the anatomical standards. In the implant customization protocol from medical image data, there are several steps that need to be followed in a sequential way, namely: Medical Image Processing and Recovering; Accurate Image Segmentation and 3D Surface Model Generation; Geometrical Customization based on CAD and CAE techniques; FEA Optimization of the Implant Geometry; and Manufacturing using CAD-CAM Technologies. This work aims to develop the necessary procedures for custom implant development from medical image data. This includes the extraction of highly accurate three-dimensional representation of the musculo-skeletal system from the Computed Tomography imaging, and the development of customized implants, given the speci c requirements of the target anatomy, and the applicable best practices found in the literature. A two-step segmentation protocol is proposed. In the rst step the region of interest is pre-segmented in order to obtain a good approximation to the desired geometry. Next, a fully automatic segmentation re nement is applied to obtain a more accurate representation of the target domain. The re nement step is composed by several sub-steps, more precisely, the recovery of the original image, considering the limiting resolution of the imaging system; image cropping; image interpolation; and segmentation re nement over the up-sampled domain. Highly accurate segmentations of the target domain were obtained with the proposed pipeline. The limiting factor to the accurate description of the domain accuracy is the image acquisition process, rather the following image processing, segmentation and surface meshing steps. The new segmentation pipeline was used in the development of three tailor-made implants, namely, a tibial nailing system, a mandibular implant, and a Total Hip Replacement system. Implants optimization is carried with Finite Element Analysis, considering the critical loading conditions that may be applied to each implant in working conditions. The new tibial nailing system is able of sustaining critical loads without implant failure; the new mandibular endoprosthesis that allows the recovery of the natural stress and strain elds observed in intact mandibles; and the Total Hip Replacement system that showed comparable strain shielding levels as commercially available stems. In summary, in the present thesis the necessary procedures for custom implant design are investigated, and new algorithms proposed. The guidelines for the characterization of the image acquisition, image processing, image segmentation and 3D reconstruction are presented and discussed. This new image processing pipeline is applied and validated in the development of the three abovementioned customized implants, for di erent medical applications and that satisfy speci c anatomical needs.
Um dos principais marcos da história moderna da medicina e a introdução da imagem médica, em meados da década de 1970. As tecnologias de imagem permitiram aumentar e potenciar o nosso conhecimento acerca da anatomia e fisiologia do corpo Humano. A capacidade de obter informação imagiológica de forma não invasiva permitiu, não são a representação tridimensional de órgãos e do sistema músculo-esquelético, mas também a simulação de procedimentos cirúrgicos, a realização de cirurgias assistidas por computador, a criação de modelos biomecânicos mais realistas, a criação de implantes personalizados, entre outros. A conjugação dos sistemas mais avançados de imagem medica com as técnicas mais avançadas de modelação e maquinagem, pode permitir o desenvolvimento de implantes personalizados mais otimizados, que vão de encontro as especificidades de cada paciente. Por sua vez, a otimização geométrica e biomecânica destes dispositivos pode permitir, quer o aumento da sua longevidade, quer o tratamento de pessoas com estruturas anatómicas que se afastam dos padrões normais. O processo de modelação de implantes a partir da imagem medica passa por um conjunto de procedimentos a adotar, sequencialmente, ate ao produto final, a saber: Processamento e Recuperação de Imagem; Segmentação de Imagem e Reconstrução tridimensional da Região de Interesse; Modelação Geométrica do Implante; Simulação Numérica para a Otimização da Geometria; a Maquinagem do Implante. Este trabalho visa o desenvolvimento dos procedimentos necessários para a criação de implantes personalizados a partir da imagem medica, englobando a extração de modelos ósseos geométricos rigorosos a partir de imagens de Tomografia Computorizada e, a partir desses modelos, desenvolver implantes personalizados baseados nas melhores praticas existentes na literatura e que satisfaçam as especificidades da anatomia do paciente. Assim, apresenta-se e discute-se um novo procedimento de segmentação em dois passos. No primeiro e feita uma pre-segmentação que visa obter uma aproximação iniciala região de interesse. De seguida, um procedimento de refinamento da segmentação totalmente automático e aplicada a segmentação inicial para obter uma descrição mais precisa do domínio de interesse. O processo de refinamento da segmentação e constituído por vários procedimentos, designadamente: recuperação da imagem original, tendo em consideração a resolução limitante do sistema de imagem; o recorte da imagem na vizinhança da região pre-segmentada; a interpolação da região de interesse; e o refinamento da segmentação aplicando a técnica de segmentação Level-Sets sobre o domínio interpolado. O procedimento de segmentação permitiu extrair modelos extremamente precisos a partir da informação imagiológica. Os resultados revelam que o fator limitante a descrição do domínio e o processo de aquisição de imagem, em detrimento dos diversos passos de processamento subsequentes. O novo protocolo de segmentação foi utilizado no desenvolvimento de três implantes personalizados, a saber: um sistema de fixação interna para a tíbia; um implante mandibular; e um sistema para a Reconstrução Total da articulação da Anca. A otimização do comportamento mecânico dos implantes foi feita utilizado o Método dos Elementos Finitos, tendo em conta os carregamentos críticos a que estes podem estar sujeitos durante a sua vida útil. O sistema de fixação interna para a tíbia e capaz de suportar os carregamentos críticos, sem que a sua integridade mecânica seja comprometida; o implante mandibular permite recuperar os campos de tensão e deformação observados em mandíbulas intactas; e a Prótese Total da Anca apresenta níveis de strain shielding ao longo do fémur proximal comparáveis com os níveis observados em dispositivos comercialmente disponíveis. Em suma, nesta tese de Doutoramento são investigados e propostos novos procedimentos para o projeto de implantes feitos por medida. São apresentadas e discutidas as linhas orientadoras para a caracterização precisa do sistema de aquisição de imagem, para o processamento de imagem, para a segmentação, e para a reconstrução 3D das estruturas anatómicas a partir da imagem medica. Este conjunto de linhas orientadoras é aplicado e validado no desenvolvimento de três implantes personalizados, citados anteriormente, para aplicações médicas distintas e que satisfazem as necessidades anatómicas específicas de cada paciente.

Повний текст джерелаCorsets have been used both to create a fashionable silhouette and as an orthopaedic treatment for spinal conditions, but skeletal changes associated with the use of corsetry are rarely reported on in the palaeopathological literature. Here, we report on a 19th-century adult male with Pott’s disease of the vertebral column and related vertebral compression deformities, which probably result from the use of a corset. Wolverhampton HB40 presented destruction of the vertebral bodies of T6 to L4, ankylosis of the apophyseal joints of L1 and L2 and an angular kyphosis of the lumbar region, the result of tuberculosis. The presence of flattened spinous processes and bilateral acute angulation of multiple ribs in the lower thoracic region is indicative of plastic deformation caused by the use of the corset. The presence of both of these changes in an adult male, at a time when the use of cosmetic corsets by men was in decline, suggests that the compression trauma was the result of an orthopaedic corset used to correct the defective posture resulting from tubercular kyphosis, although corset use to obtain a fashionable silhouette cannot be ruled out.

Повний текст джерелаPatients with isolated traumatic limb injuries usually consult primary care for first line treatment. The primary care physician will often refer the patient to an orthopaedic surgeon when needed. The research objective was to study the referral mechanism to an Orthopaedic Service in a Level 1 Trauma Center for patients with an isolated limb injury. Access to specialized care and quality of primary care are used to describe the referral mechanism. We studied 166 consecutives patients referred to orthopaedic surgery over a 4 months period. Before the orthopaedic visit, 23 % had seen 2 or more doctors for their injury. The time between the first primary care visit and the orthopaedic evaluation was greater (68 hours) then the interval between the injury and the visit with primary care (21 hours). Among the cases that were considered urgent, 36 % had not been seen within the recommended delay. Quality of initial care was judged sub optimal for 49 % of patients in terms of immobilization, analgesia and/or walking aids. Factors associated with decreased access or quality of care are: smoking, younger age, living far from the hospital, consulting first in a private clinic, lower limb or soft tissue injury and a patient‟s low self-perception of severity. These results underline the necessity of targeting primary care education and improving the referral mechanism for patients with isolated limb injuries.
