BACKGROUND: Chronically dislocated hips (>6 weeks) are usually the consequence of difficulties accessing appropriate healthcare in a timely fashion after dislocation; this explains why they are more common in developing countries. Due to a lack of research, there is currently no consensus on the best treatment available for patients presenting with this condition. Therefore, it is important to assess the treatments available so as to ensure that doctors adequately manage those presenting with this debilitating condition in the future...

E-learning is the use of internet-based resources in education. In the field of surgical education, this definition includes the use of virtual patient cases, digital modeling, online tutorials, as well as video recordings of surgical procedures and lectures. In recent years, e-learning has increasingly been considered a viable alternative to traditional teaching within a number of surgical fields. Here we present (1) a systematic review of literature assessing the efficacy of e-learning modules for orthopedic education and (2) a discussion of their relevance...

Stimulation of mesenchymal stem cells (MSC) by bone morphogenetic protein-7 (BMP-7) leads to superior bone formation in vitro. In this in vivo-study we evaluated the use of BMP-7 in combination with MSC isolated from reaming debris (RIA-MSC) and iliac crest bone marrow (BMSC) with micro-computed tomography (mCT)-analysis. β-Tricalciumphosphate scaffolds coated with BMSC and RIA-MSC were stimulated with three different BMP-7-concentrations and implanted ectopically in severe combined immunodeficiency (SCID) mice...

Over the past decade there have been increasing reports of atypical femoral fractures (AFFs) associated with bisphosphonate use. Reported cases of bilateral involvement usually refer to sequential injuries, or a complete fracture with an incomplete injury to the contralateral limb. In this case report we describe simultaneous, bilateral, complete atypical femoral fractures following a simple fall. A history of prodromal pain, previous radiological evidence of cortical thickening and long term alendronate therapy for osteoporosis secondary to corticosteroid treatment paint a classical picture of the presentation of an atypical fracture pattern of which orthopaedic surgeons should be aware...

The existing modalities of bone diagnosis including X-ray and ultrasound may cite drawback in some cases related to health issues and penetration depth, while the ultrasound modality may lack image quality. Photo acoustic approach however, provides light energy to the acoustic wave, enabling it to activate and respond according to the propagating media (which is type of bones in this case). At the same time, a differential temperature change may result in the bio heat response, resulting from the heat absorbed across the multiple materials under study...

BACKGROUND: Undergoing a major surgical intervention such as total hip arthroplasty (THA) with an underlying clotting disorder like haemophilia poses its own unique challenges. Despite the advances in factor replacement and medical management, the potential for excessive and uncontrolled haemorrhage still exists. The aim of this study was to quantify blood loss, peri-operative transfusion requirements and risk of haematoma formation in a cohort of patients with haemophilia undergoing THA...

INTRODUCTION: Fracture of the distal radius is a common clinical problem. Complex fracture requires open reduction and stabilization with plating to restore anatomy. Dorsal plating has advantages of buttressing the fracture better but often complicated with tendon problems as per literature. The rate of complications however, was not compared between the low-profile dorsal and the volar plates. METHODOLOGY: This was a retrospective study on seventy one patients with dorsally angulated or displaced distal radius fractures, who underwent fixation of fractures with either dorsal or volar locking plate from Jan - Nov 2012...

OBJECTIVES: The study's aim is to calculate the parameters for retrograde insertion points for fixed superior pubic ramus fractures. METHODS: From the pubic symphysis, diameter and length of the screw were measured, as well as the angle between the screw axis and the 3 planes. RESULTS: When the diameter was fixed at 4.5 mm, the maximum lengths were 125 mm and 119 mm. CONCLUSIONS: When the fracture occurs in Zone I, the penetration point could be selected in the pubic symphysis pubis angle to ensure that medial fracture fragments have sufficient screw channel length...

PURPOSE: We aimed to examine the clinical outcomes of proximal humeral fractures treated with different intramedullary nail shapes. METHODS: Thirty-seven patients were divided into two groups depending on the implant shape. We also defined F group as a subgroup of fracture classification. RESULTS: In the F group, the flexion of the shoulder joint was significantly greater in S (mean, 134.6°) than in C groups (mean, 109°) (p = 0.04). The complication rate was significantly larger in the C group (p = 0...

We reviewed 40 complex tibial non-unions treated with Taylor Spatial Frames. 39 healed successfully. Using the ASAMI scoring, we obtained 33 excellent, 5 good, 1 fair and 1 poor bone results. The functional results were excellent in 29 patients, good in 8, fair in two and poor in one. Mean patient satisfaction score was 95%. All but one patient would have the same treatment again. 28 of the 36 patients in work when injured, returned to work at the time of their final review. Four patients had an adverse event requiring significant intervention...

BACKGROUND: Chronic hip dislocation associated with acetabular apophyseal avulsion in adolescence is rare. Whilst superior acetabular rim fractures have a documented theoretical risk of hip instability, we have not found a case of chronic dislocation resulting from this. METHODS: We report a case of a 12-year-old healthy boy who initially sustained a missed right acetabular apophyseal avulsion after falling from a quad bike. This was missed on the initial radiograph and a subsequent radiograph following weight bearing a few days later showed a hip dislocation that was also missed...

The aneurysmal bone cyst (ABC) is a benign osteolytic bone neoplasm. Although most ABC is asymptomatic, in some cases they produce a mass effect, impinging against soft tissues or interfering with joint function. The authors present a rare case report of a lunate ABC successfully treated by curettage and bone grafting, and review the literature of this pathology.

In current scenario there is an emerging trend to consider osteoarthritis (OA) phenotypes based on their risk factors and therefore offering potential for targeted therapies. OA prevalence with other coexistence diseases, such as systemic arterial hypertension, cardiovascular disease, diabetes, and dyslipidemia are increasing. Majority of OA associated with MetS, despite overweight of patients, the occurrence of OA in joints do not bear load suggest, the chronic inflammation status existing in patients with MetS can alter the metabolism of cartilage, regardless of excessive weight...

Metastases to proximal femur are common and surgery is often suggested to prevent fractures; otherwise it is necessary in cases where this has already occurred. Adjuvant radiotherapy is necessary to reduce the risk of local progression. Nevertheless, the success or failure of radiation therapy treatments depends upon the accuracy in which target identification is correct and dose prescription is fulfilled. Unfortunately, the use of titanium nails consistently limits radiation dose; indeed, the presence of ferromagnetic artifacts interferes with target identification...

PURPOSE: The absence of a best practice treatment standard contributes to clinical variation in medicine. Often in the absence of evidence, a standard of care is developed and treatment protocols are implemented. The purpose of this study was to examine whether the standard of care for the treatment of nondisplaced scaphoid fractures is uniform among orthopedic surgeons. METHODS: A survey of orthopedic surgeons actively practicing in the US or abroad was conducted to elicit preferred treatment strategies for nondisplaced scaphoid fractures...
