BACKGROUND: The Military Orthopaedic Trauma Registry (MOTR) was designed to replicate the Department of Defense Trauma Registry's (DoDTR's) role as pillar for data-driven management of extremity war wounds. The MOTR continuously undergoes quality assurance checks to optimize the registry data for future quality improvement efforts. We conducted a quality assurance survey of MOTR entrants to determine if a simple MOTR data pull could provide robust orthopedic-specific information toward the question of causes for late amputation...

Osteoporosis, a systemic metabolic disease of bone, is characterized by low bone mass and altered trabecular pattern, leading to increased risk of fractures. It increases in prevalence with age, especially in postmenopausal women, and can have other secondary causes. Radiologic evaluation of osteoporosis has historically used conventional radiography, which demonstrates cortical thinning, increased radiolucency, and altered trabecular patterns, and also aids in assessing vertebral fractures. Many indexes have been devised, such as the Saville index for the degree of radiolucency, and the Genant grading system for vertebral fractures...

The foot-ankle complex is frequently injured in a wide array of debilitating events such as car crashes. Numerical models and experimental tests have been used to assess injury risk, but most do not account for the variations in ankle posture that frequently occur during these events. In this study, the positions of the bones of the foot-ankle complex (particularly, the hindfoot) were quantified over a range of postures. Computed tomography scans were taken of a male cadaveric leg under axial loading with the ankle in five postures in which fractures are commonly reported...

: In hemodialysis patients, vertebral fractures were associated with elevated sclerostin levels, suggesting that sclerostin could reflect bone fragility in these patients. INTRODUCTION: Fragility fractures are common in hemodialysis patients. The aims of our study were to determine the prevalence of vertebral fracture and analyze associations between sclerostin serum levels and vertebral fractures in hemodialysis patients. METHODS: Ninety-two hemodialysis patients and 100 controls matched for age and sex were studied...

BACKGROUND: Calcaneal fractures are commonly seen and treated in the emergency department. There are subsets of calcaneal fractures that pose a high risk to the adjacent soft tissue of the heel and can result in full-thickness tissue necrosis. OBJECTIVE: To identify which calcaneal fractures need to be managed within hours and triaged to the orthopedic team and which can be temporized in a neutral or plantarflexed ankle splint and seen in an outpatient setting. DISCUSSION: Tongue-type calcaneal fractures and tuberosity fractures must be triaged appropriately within the first few hours of presentation to prevent skin compromise...

Prolonged immobilization in hospitalized children can lead to fragility fractures and muscle contractures and atrophy. The purpose of this study was to develop a lower-extremity disuse rabbit model with musculoskeletal changes similar to those observed in children subjected to prolonged immobilization. Six-week-old rabbits were randomly assigned to control (CTRL, n=4) or bilateral sciatic and femoral neurectomy (bSFN, n=4) groups. Trans-axial helical CT scans of each rabbit׳s hind limbs were acquired after eight weeks...

Intra-articular fracture of the calcaneus is one of the most displeasing fractures if not properly managed. Open reduction and internal fixation have been associated with a high incidence of postoperative soft tissue complications. Closed reduction and percutaneous fixation have resulted in a greater incidence of postoperative subtalar osteoarthritis with improper reduction of the articular surface. In the present study, a mini-open approach was used in cases of failure of articular surface restoration with closed reduction...

OBJECTIVES: The objective of the current study was to examine trends in ankle/foot (A/F) injuries during the period 2001-2014, in order to determine whether the incidence of these injuries has changed and whether a previously identified difference in risk by gender still existed. In addition, other driver and crash-related risk factors were examined separately for men and women. METHODS: Passenger vehicle drivers aged 16+ were identified from NASS-CDS; weighted data were analyzed for model years 2001-2014...

BACKGROUND: Displaced intra-articular calcaneus fractures (DIACFs) are the most common type of calcaneus fracture. The differences in therapeutic effectiveness between cannulated screw fixation (CSF) and plate fixation are still unclear. Thus, in this meta-analysis, we evaluated the therapeutic effectiveness of these two fixation methods. MATERIALS AND METHODS: We searched for all publications on DIACFs fixated with cannulated screws or plates in the following electronic databases: Pubmed, Cochrane, Embase and CNKI...

UNLABELLED: PURPOSE OF THE STUDY The aim of the study was to analyse the options for sustentacular screw placement in osteosynthesis of intra-articular fractures of the heel bone and to assess the effect of various screw positions on failure to maintain the reduction in the postoperative period. In addition, problems related to screw-end protrusion over the medial cortical bone or to screw penetration into the talocalcaneal joint were assessed. MATERIAL AND METHODS The group comprised 23 patients with a total of 25 intra-articular fractures of the heel bone treated by surgery...

BACKGROUND: Pseudomyogenic hemangioendothelioma is a rare soft tissue tumor usually found in young adults, predominantly males. Fibrous dysplasia is a common benign bone tumor, which accounts for 5~7 % of all the primary benign bone tumors. However, pseudomyogenic hemangioendothelioma secondary to fibrous dysplasia is extremely rare. To the best of our knowledge, this is the first case of pseudomyogenic hemangioendothelioma secondary to fibrous dysplasia. CASE PRESENTATION: This study describes a case of a 14-year-old female who suffered from pseudomyogenic hemangioendothelioma secondary to fibrous dysplasia of the left lower extremity...

PURPOSE: Fractures of the lower extremity, particularly of the femur and acetabulum, may be difficult to immobilize with splinting alone. These injuries may be best stabilized with the application of various types of skeletal traction. Often, traction is applied percutaneously in an emergent setting, making the knowledge of both superficial and deep anatomy crucial to successful placement. METHODS: Review was performed via PubMed search as well as referencing the Orthopaedic literature...

One of the most frequent complications after intraarticular fracture of the calcaneus is the development of posttraumatic arthritis of the subtalar joint. If conservative measures fail in the treatment of this condition, consideration of arthrodesis should be given. This video depicts the preoperative assessment and surgical technique applied to one such 54-year-old patient who had undergone internal fixation of a calcaneal fracture 9 years before. Shown within the video is exposure of the subtalar joint through a lateral incision, joint preparation, and the application of stable fixation...

The use of external fixation for intra-articular calcaneal fractures is increasing in popularity. Studies have shown fine wire and monoaxial external fixation to be a viable surgical alternative to more invasive methods of open reduction and internal fixation of the calcaneus. However, there is an absence of literature that quantifies the risk of pin insertion for monoaxial fixation. This study aimed to determine the safety of inserting monoaxial pins within the calcaneus to house the Orthofix Calcaneal Mini-Fixator...

Minor injuries of the anterior process of the calcaneus occur frequently and most heal uneventfully. The present series reports on 6 patients with persistent complaints after anterior process avulsion fractures. The avulsed fragments of the anterior process at the calcaneocuboid joint were surgically excised in all, which resolved the complaints completely in 4 patients and reduced the complaints significantly in 2. If conservative measures fail and the complaints are refractory, debridement of the anterior process avulsion fractures at the calcaneocuboid joint could be a viable option...

BACKGROUND: Bohler's angle (BA) is the most commonly utilized radiographic measurement in the study of calcaneus fractures and has been shown to be prognostic in nature. Therefore, it is critical that the measurement of BA be accurate as both therapeutic and prognostic information relies on it. Oblique lateral radiographs can be a cause of error in BA measurements. However, measurement error and the effects of X-ray beam obliquity on BA have not been established in the literature. The purpose of this study was to determine measurement error and understand the effects of X-ray beam's obliquity on the measurement of BA...

The locking plate and percutaneous crossing metallic screws and crossing absorbable screws have been used clinically to treat intra-articular calcaneal fractures, but little is known about the biomechanical differences between them. This study compared the biomechanical stability of calcaneal fractures fixed using a locking plate and crossing screws. Three-dimensional finite-element models of intact and fractured calcanei were developed based on the CT images of a cadaveric sample. Surgeries were simulated on models of Sanders type III calcaneal fractures to produce accurate postoperative models fixed by the three implants...

BACKGROUND: Structural allografts have been used to correct deformities or to fill bone defects secondary to tumor excisions, trauma, osteochondral lesions, or intercalary arthrodesis. However, the quality of published evidence supporting the use of allograft transplantation in foot and ankle surgery has been reported as fair. The purpose of this study was to report the overall survival of structural allograft in the foot and ankle after tumor resection, and the survival according to the type of allograft and the complication rates in the medium to long term...

BACKGROUND: Intra-articular calcaneus fractures result in heel shortening, widening, varus malalignment, and loss of height. Little has been written regarding superior displacement of the calcaneal tuber, which warrants consideration as previous literature has demonstrated issues arising from a shortened triceps surae. We sought to determine the amount of tuber elevation seen in calcaneus fractures as compared to normal calcanei and propose 2 new measurements that aid in quantifying displacement and may aid in the surgical management of calcaneus fractures...
