Résumé :

Objective To evaluate the effects of active infant orthopedic treatment on dental arch relationships and determine the effect on maxillary growth in children born with unilateral complete cleft lip and palate (UCCLP). Design The GOSLON Yardstick was used to assess dental models taken on patients treated with and without active infant orthopedics. Patients Two groups of nonsyndromic Caucasian children born with UCCLP (total n = 40), all treated by the same surgeon and ranging from 5 to 10 years of age, were evaluated. Interventions One group had a Latham dentomaxillary alignment (DMA) appliance inserted at 5 to 6 weeks of age, after which a lip-nasal adhesion was performed at an average age of 3.5 months. This was followed by more definitive nasolabial repair at the average age of 5.9 months. Those patients treated without preoperative orthopedics underwent a lip-nasal adhesion at average age 1.5 months followed by nasolabial repair at average age 5.1 months. Main Outcome Measures Randomized assessments using the GOSLON Yardstick were done independently at two separate times by three different examiners. Differences in GOSLON scores between the active orthopedic group and nonorthopedic group were evaluated by both categorical and continuous statistical analyses. Results The mean GOSLON score was 3.30 for the orthopedic group and 3.21 for the nonorthopedic group. There was no significant group difference in the modal scores of the two groups. Conclusions This study showed that active infant orthopedics does not affect the dental arch relationships in preadolescent children with repaired UCCLP, compared with a similar group treated without orthopedic intervention at this center.

Résumé :

Electronic cigarette (EC) use is highly prevalent, especially in the adolescent population, where 29% of Canadian adolescents have used an EC in the past thirty days per national surveys. Our pediatric orthopedic referral centre observed a cluster of delayed unions of bone fractures in adolescents using ECs and present the case series here. We then asked whether electronic cigarettes impair bone healing or influence orthopedic outcomes. A PRISMA-compliant systematic review was carried out, which revealed no human clinical studies and a general paucity of evidence around ECs and musculoskeletal health. The existing experimental evidence relevant to orthopedics is summarized. The effect of ECs on the musculoskeletal system is poorly understood and is a target for further research.

Résumé :

As the COVID-19 pandemic continues to spread across Saudi Arabia, as many other health departments or specialties within the field of medicine and surgery, COVID-19 has affected the field of orthopedics to a greater extent, This might have affected not only the timely and effective care for orthopedic patients but also have resulted in new directions and plans in the field of orthopedics that will shift the care degree. In addition, orthopedic surgeons might experience challenges in providing effective and required for their patients with an overall decline of care due to COVID-19 pandemic. Moreover, it is also essential to reflect on the future directions and changes that need to be adopted by the health specialists working in the field of orthopedics. This can include the reopening of facilities for elective surgery. Given the current circumstances, much remains unknown about COVID-19. It is important that individuals continue to follow guidance of Saudi ministry of health, that said, the Saudi of Orthopaedic Surgeons like to share some important considerations that individuals should consider before making any decisions.

Résumé :

Only select tissues and organs are able to spontaneously regenerate after disease or trauma, and this regenerative capacity diminishes over time. Human stem cell research explores therapeutic regenerative approaches to treat various conditions. Mesenchymal stem cells (MSCs) are derived from adult stem cells; they are multipotent and exert anti-inflammatory and immunomodulatory effects. They can differentiate into multiple cell types of the mesenchyme, for example, endothelial cells, osteoblasts, chondrocytes, fibroblasts, tenocytes, vascular smooth muscle cells, and sarcomere muscular cells. MSCs are easily obtained and can be cultivated and expanded in vitro; thus, they represent a promising and encouraging treatment approach in orthopedic surgery. Here, we review the application of MSCs to various orthopedic conditions, namely, orthopedic trauma; muscle injury; articular cartilage defects and osteoarthritis; meniscal injuries; bone disease; nerve, tendon, and ligament injuries; spinal cord injuries; intervertebral disc problems; pediatrics; and rotator cuff repair. The use of MSCs in orthopedics may transition the practice in the field from predominately surgical replacement and reconstruction to bioregeneration and prevention. However, additional research is necessary to explore the safety and effectiveness of MSC treatment in orthopedics, as well as applications in other medical specialties.

Résumé :

Magnesium (Mg)-based alloys have become an important category of materials that is attracting more and more attention due to their high potential use as orthopedic temporary implants. These alloys are a viable alternative to nondegradable metals implants in orthopedics. In this paper, a detailed overview covering alloy development and manufacturing techniques is described. Further, important attributes for Mg-based alloys involved in orthopedic implants fabrication, physiological and toxicological effects of each alloying element, mechanical properties, osteogenesis, and angiogenesis of Mg are presented. A section detailing the main biocompatible Mg-based alloys, with examples of mechanical properties, degradation behavior, and cytotoxicity tests related to in vitro experiments, is also provided. Special attention is given to animal testing, and the clinical translation is also reviewed, focusing on the main clinical cases that were conducted under human use approval.

Résumé :

The oral cavity harbors complex microbial communities, which leads to biomaterial-associated infections (BAI) during dental and orthopedic treatments. Conventional antibiotic treatments have met great challenges recently due to the increasing emergency of drug-resistant bacteria. To tackle this clinical issue, antibacterial surface treatments, containing surface modification and coatings, of dental and orthopedic materials have become an area of intensive interest now. Among various antibacterial agents used in surface treatments, metallic agents possess unique properties, mainly including broad-spectrum antibacterial properties, low potential to develop bacterial resistance, relative biocompatibility, and chemical stability. Therefore, this review mainly focuses on underlying antibacterial applications and the mechanisms of metallic agents in dentistry and orthopedics. An overview of the present review indicates that much work remains to be done to deepen the understanding of antibacterial mechanisms and potential side-effects of metallic agents.

Résumé :

Research background: The industrialized world is experiencing a far-reaching crisis situation due to the pandemic triggered by COVID-19. Economies with global value chains are particularly badly affected, including Germany. The associated glocal effects force the management of organizations, including SMEs in the healthcare sector, to place risk management on a strategic level. Purpose of the article: This research contribution is intended to provide organizations in times of crisis with a profitable outline of the intelligent use of business management tools in the Corona crisis. The focus is on the determination of significant value and risk drivers using SWOT analysis, communicative reporting and the creation of key figures for decision support. The results of the 2nd survey of the Federal Guild of Orthopedic Technology on the Corona effects show high sales and order drops due to a sharp decrease in the frequency of customers at orthopedic companies compared to grocery retailers. In the Corona crisis, both sectors are considered to be systemically relevant and are of major importance for the state community. Methods: The authors have analyzed pandemic-related secondary data in order to show the economic effects of COVID-19 for SMEs in the healthcare sector and to comprehensively record the problem. It was carried on already available data from WHO, DeSTATIS as well as specialist organs of technical orthopedics were used. Findings & Value added: In a crisis, managers are primarily challenged to evaluate and redefine their previous management philosophy. Proactive and cross-functional cost management across the entire value chain is essential to ensure the continued existence of the company.

Résumé :

The objectives of this study are to investigate the influence of class III orthopedic forces generated by repelling rare earth magnets of class III magnetic orthopedic appliance (MOA-III) on the zygmaticomaxillary suture of Rhesus monkeys. Six male Rhesus monkeys in the stage of mixed dentition were used in this study. Fluorescent dyes were injected intravenously in each animal before and during the experimental period. Distinct changes from physiologic growth remodeling were observed in some sutures but not in the control groups. No inflammation was noted in both experimental and control monkeys. The results show that MOA-III is a small intraoral appliance to treat class III malocclusion, and the 300gm per side heavy orthopedic forces are safe and effective for Rhesus monkey.

Résumé :

Although custom-made foot orthotics are commonly prescribed to relieve lower limb injuries, few studies have documented their effects on the biomechanics of locomotion. The objective of this project was to quantify the effect of orthotic wear on kinematic, kinetic and electromyographic characteristics of the legs during walking and running. Fourteen subjects with custom-made foot orthotics were asked to run and walk over a 10-m walkway. Kinematic, kinetic and electromyographical parameters were recorded during all trials. One-way repeated measures ANOVA and paired students t-tests were used to evaluate the effect of orthotic wear as well as foot type (flat, normal). With orthotic wear, the activity of the soleus muscle was decreased for both groups of subjects with and without flat feet during running. The effect of orthotic wear on all other parameters was not significant. More in-depth studies are needed to generalize these results on the overall population of orthotic wearers.

Partial foot amputation is becoming more prevalent and costly and if not treated correctly can lead to higher levels of amputation. Despite this, partial foot orthotic research and development has been inadequate. Furthermore, in order to contribute to improved orthotic management, there is a need to understand the biomechanical discrepancies during gait. Biomechanical goals of orthotic fitting include normalizing the three functional impairments of the transmetatarsal amputee. The first goal is to improve balance, the second is to normalize the toe-off phase of gait, and the third goal involves supporting the plantar surface of the foot to evenly distribute pressure. In this study, all subjects were evaluated with a below-ankle condition and an above-ankle condition. The below-ankle condition consisted of a total contact foot orthosis fitted into Drew' shoes with rocker bottom soles. The below-ankle orthosis was then fitted with a Blue Rocker© ankle foot orthosis and gait was re-evaluated as the above-ankle orthotic gait condition. Three specific goals were proposed in this study: 1) to determine the differing, if any, effects on balance and vertical ground reaction symmetry during level walking and obstacle crossing between the two orthotic designs, 2) to determine the plantar pressure distribution differences between a below-ankle and an above-ankle design, 3) to learn about patient preferences to provide realistic feedback for quality patient care. We hypothesized that improved balance, symmetry and distribution of pressure would occur with the above-ankle design in individuals with greater disability.

Texte intégral

Résumé :

Reverse shoulder arthroplasty (RSA) is performed to decrease pain and improve function and range of motion (ROM) primarily for patients with rotator cuff arthropathy, an arthritis of the shoulder secondary to rotator cuff insufficiency. However, RSA has suffered from high early to mid-term rates of complication, with instability being one of the most common. The shoulder biomechanics post-RSA depend on multiple factors such as implant geometry, positioning, and cuff integrity. This study built upon prior finite element (FE) analysis of RSA to investigate the effects of glenoid lateralization and retentive liner design on shoulder stability. A previously validated FE model was extended to model shoulder external rotation (ER) after implantation of the Zimmer Trabecular Metal RSA system. The FE model included the scapula bone with an implanted glenosphere implant, the humerus bone with implanted humeral sections of the RSA implant, and muscle tendons representing the subscapularis, infraspinatus, and deltoid. Six different models matched glenospheres in three cases of lateralization (2mm, 4mm, and 10mm) with two humeral poly liner designs (normal: 150° neck shaft angle or retentive: 155° neck shaft angle). Using Abaqus/Explicit FE software, the proximal ends of the soft tissues were pulled to their anatomical positions, and then fixed in space while the humerus was externally rotated 80° about the humeral long axis from a neutral position with the shoulder abducted 25°. The displacements, deltoid and subscapularis forces, impingement-free ROMs, and subluxation gap distances were recorded. Although greater glenosphere lateralization was associated with higher impingement-free ROM, larger deltoid and subscapularis forces developed. Deltoid tension contributes to shoulder stability and control, but elevated amounts of deltoid tension may contribute to scapular fractures and greater stress at impingement sites post-RSA. Further analysis such as inclusion of more anatomical features and additional motions may offer greater insight to orthopedic surgeons when planning for RSA insertion.

Résumé :

Introduction The aim of the present study is to evaluate the skeletal modifications induced by maxillary expansion supported by palatal micro-implants and localized osteotomies produced with minimally invasive surgical technique in young-adult and adult patients. In the present investigation, osteotomies had a lower extension than the ones used in conventional surgically assisted rapid palatal expansion (SARPE), to adopt a minimally invasive surgical technique that can be performed with greater comfort for the patient and less post-operative sequelae. More in detail, the localized osteotomies were executed only in the anterior part of the midpalatal suture and bilaterally at the basis of the zygomatic process of the maxilla without involvement of the piriform rim. These areas represent a great resistance to the lateral maxillary movement. Furthermore, they are of simple surgical access and don’t present important arterial plexuses. Patients requiring micro-implant supported maxillary expansion and/or SARPE routinely undergo a pre-treatment cone-beam computed tomography (CBCT) of the skull, to plan the surgical operation and, one month after treatment a secondary CBCT for a surgical and orthodontic control. CBCT is a low radiation tomography, extensively used in maxillofacial surgery and in dentistry. For the implementation of this study, that aims at evaluating the efficacy of micro-implant-supported maxillary expansion in combination with localized osteotomies, only radiologic exams that are anyway needed for the planning and post-treatment evaluation were used. Aim The aim of the present study is to evaluate the advantages introduced in the treatment of maxillary constriction by the therapy with micro-implant supported Maxillary Skeletal Expander (MSE) and localized osteotomies in young-adult and adult patients. The main objective is to evaluate the efficacy of the technique, by measuring the movement of skeletal landmarks in the midface, particularly on the maxillary and zygomatic bones, and on the lateral wall of the nose, by comparing the pre-treatment and post-treatment CBCT. For this particular technique, a new methodology for digital planning of position of MSE and miniscrews on patient CBCT was developed. Furthermore, incorporation of 2 additional miniscrews to the original MSE design, which conventionally features only 4 miniscrews, was developed with the aid of computer aided design – computer aided manufactured (CAD-CAM) technology. Methods The study presented the following steps: ▪ Development of a digital planning methodology for positioning the miniscrews and MSE appliance on pre-treatment CBCT ▪ Development of a CAD-CAM methodology for incorporating 2 additional miniscrews to the original MSE design with 4 miniscrews ▪ Selection of patients with age above 17 years, without congenital craniofacial syndromes, who require intervention of maxillary skeletal expansion ▪ Acquisition of initial CBCT with 17 x 13.5 cm field of view (FOV) ▪ Intervention of maxillary expansion supported by palatal micro-implants and localized osteotomies executed with minimally invasive surgical technique ▪ One month after treatment, acquisition of post-treatment CBCT with 17 x 13.5 cm FOV ▪ Analysis of skeletal modifications in the midface (maxillary bone, sphenoid bone, zygomatic arch, nasal cavity, etc.), by comparing the pre- and post- treatment CBCT with a 3D software (OnDemand software by Cybermed) Results The new methodology allowed the digital planning of MSE and miniscrews positioning on patients’ CBCTs, and the incorporation of two additional miniscrews to the original MSE design through CAD-CAM technology. In the clinical trial, a total of four patients had an average age of 27.6 years (range 22.1 – 39.9 years). MSE appliance was activated by an average of 6.0 mm and generated a parallel split of the midpalatal suture of 3.4 mm, 3.0 mm and 3.6 mm at anterior nasal spine (ANS), nasopalatine foramen (NPF) and posterior nasal spine (PNS), respectively. Skeletal modifications were found in all CBCT sections evaluated in the study (axial palatal, upper nasal, coronal zygomatic, axial zygomatic), indicating that all midfacial bones are affected by maxillary expansion with MSE and localized osteotomies. Particularly, skeletal changes were noticed also in CBCT sections above the lateral maxillary osteotomies (LMOs), in the maxilla, zygomatic bone, zygomatic arches, and nasal cavity. In the upper nasal section (UNS) the maxilla was laterally displaced by 2.4 mm and 0.9 mm, at its anterior and posterior extremities, respectively. The frontozygomatic angle (FZA) increased by 1.9° (average of right and left side), while the lower interzygomatic distance increased by 2.9 mm, indicating a rotation of the zygomatic bone in a lateral direction. The zygomatic arch was affected by bone bending phenomena and was deflected in an outward direction, with increase in the anterior intermaxillary distance by 1.7 mm and in the posterior inter-zygomatic distance by 1.6 mm. The nasal width (NW) parameter increased by 2.9 mm with treatment: this anatomical finding is the basis for a potential improvement in nasal breathing for patients suffering from increased nasal airway resistance. The cited modifications in skeletal structures above lateral maxillary osteotomies (LMOs) are most likely due to the fact that LMOs didn’t involve the piriform rim of the maxilla, and this point needs further investigations. Regarding dentoalveolar modifications, the inter-molar distance increased by 7.4 mm, and molars underwent a small dentoalveolar tipping in a buccal direction by 1.1° (average of right and left side), as evidenced by the change in molar basal bone angle (MBBA). No intra-operatory hemorrhage nor post-operatory bleeding was reported in treated patients, probably due to the lack of pterygopalatine suture surgical disjunction. A limitation of the study is its small sample size, represented by 4 patients. A larger number of patients is required to confirm the above results.

Résumé :

A computer-aided simulation model is developed to aid in the design and optimization of orthopaedic trauma implants. The developed model uses digital imaging, computer-aided solid modeling, and finite element methods in order to study the effects of various geometric parameters of fixation devices in orthopedic surgery practice. The results of the present simulation model would lead to the determination of the optimum implant design that provides the best match with the geometry of the human femur — reducing the risk of over-stressing bone tissue during implant insertion. The effectiveness of the presented simulation model is demonstrated through the design of intramedullary (IM) nails used in treating femoral shaft fractures. CT scans were taken of forty intact human femora. A technique was developed in order to digitally reconstruct the scans into 3D solid models using image segmentation, surface simplification, and smoothing methods while maintaining accurate representation of the original scans. Each resulting surface model is characterized by a network of nearly equilateral triangles of approximately the same size allowing for quality finite element meshing. Femoral lengths, curvature, shaft diameters, and location of maximum curvature were then quantified. An average geometric model was then generated for the investigated sample by averaging corresponding nodal coordinates in each femur model. Using the average model, a length-standardized function representing the curvature of the medullary canal was derived to create a geometrically optimized IM nail for the entire sample. “Virtual surgery” simulating the insertion process was then performed using finite element methods in order to validate the proposed optimal IM nail design. The results of both the optimum nail and a current nail were compared using the femur having the highest curvature in the sample. The present study shows that the developed simulation model leads to a nail design that reduces the insertion-induced stress within the femur to an acceptable level compared to current nails.

Résumé :

Biodegradable magnesium-calcium (MgCa) alloys are capable of gradually dissolving and becoming absorbed in the human body after implantation. The critical issue that hinders the application of MgCa implants is their fast corrosion rate in human body fluids. A promising approach to tackle this issue is to tailor surface integrity of orthopedic implants for tuning the corrosion kinetic. The synergistic dry cutting and burnishing is used in this study to modify surface integrity of MgCa0.8 (wt%) implants for controlled corrosion performance. The effects of cutting speed and rolling force, as key parameters in the synergistic dry cutting-finish burnishing, on the electrochemical responses of the processed surfaces are investigated in the simulated body fluid (SBF). Potentiodynamic polarization curves are measured, and morphology and elemental composition of corroded surfaces are studied utilizing scan electron microscopy (SEM) and energy dispersive spectroscopy (EDS), respectively.

Résumé :

Review question / Objective: Does the volume of the upper airway change after an orthodontic intervention? P: growing subjects, adults; I: orthodontic treatment, dentofacial orthopedics, extractions; C: untreated subjects and/or non-extractions; O: volumetric changes of the upper airway measured on CBCT scans. Condition being studied: The primary objective of orthodontic treatment is to establish optimal dental and/or skeletal relationship in harmony with the soft tissue morphology and functioning. In addition, un-impeding or facilitating airway growth and development is an important objective, especially in patients susceptible for airway obstruction or sleep apnea. It is therefore important to look into the effect of various orthodontic treatments on the 3D volumetric changes of the upper airway. Compared with the use of traditional 2D lateral cephalograms, CBCT scans provide the opportunity to perform measurements in more dimensions on the airway with demonstrated reliability. This systematic review therefore includes studies using CBCT scans for evaluation of the airway.
