BACKGROUND: There are several different techniques commonly used to perform intramedullary (IM) nailing of the femur to fix femoral fractures. We sought to identify significant differences in outcomes of studies comparing 1) trochanteric and piriformis entry and 2) antegrade and retrograde entry in IM nailing of the femur. METHODS: We searched MEDLINE, Cochrane and Embase databases and the Orthopaedic Trauma Association and American Academy of Orthopaedic Surgeons websites for comparative studies published from inception to November 2015...

INTRODUCTION: Heterotopic ossification (HO) is known to be a common complication after total hip arthroplasty (THA). The minimal invasive (MIS) modified anterolateral approach has become popular in combination with a short stem. We analysed the incidence of HO following short-stem THA using this approach in combination with a postoperative administration of nonsteroidal anti-inflammatory drugs (NSAIDs). MATERIALS AND METHODS: 216 short stems were implanted in 162 patients...

REVIEW
Ravi Mittal
Posttraumatic stiff elbow is a frequent and disabling complication and poses serious challenges for its management. In this review forty studies were included to know about the magnitude of the problem, causes, pathology, prevention, and treatment of posttraumatic stiff elbow. These studies show that simple measures such as internal fixation, immobilization in extension, and early motion of elbow joint are the most important steps that can prevent elbow stiffness. It also supports conservative treatment in selected cases...

INTRODUCTION: The incidence of geriatric acetabular fractures continues to increase due to demographic changes. In the elderly, anterior column fractures are common, and standard approaches are associated with a considerable risk for surgery-associated complications. Therefore, a minimally invasive approach was developed in our department. The aim of this study was to examine early and mid-term results regarding the use of this novel two-incision minimally invasive (TIMI) approach in patients aged over 55 years with acetabular fractures...

BACKGROUND: Neurogenic heterotopic ossification (NHO) is usually treated by surgical excision. Post-operativeinfection (POI) is a possible complication, whose epidemiology, causative organisms, and risk factors are poorly known.We therefore conducted a case-control study to 1) identify the risk factors for POI after surgical excision of NHO at the hip, 2) determine the frequency of POI, 3) and identify the causative organisms. HYPOTHESIS: Risk factors for POI after NHO excision at the hip can be identified...

Arthroscopic surgery of the hip, compared to that of the knee or the shoulder, has only recently been developed in any significant way. Current indications for arthroscopic surgery of the hip include: diagnosis and treatment of lesions symptomatic of the acetabular labrum, femoroacetabular impingement (FAI), chondral lesions, joint infections, lesions of the teres ligament, impingement of the psoas tendon, pathology of the peritrochanteric space, external snapping hip (coxa saltans), and traumatic and atraumatic instability...

Studies presented here, using a murine model of bone morphogenetic protein type 2 (BMP2)-induced heterotopic ossification (HO) show that the protein initiates HO by signaling through progenitors in the endoneurium of peripheral nerves. In the mouse, these cells were identified in the endoneurium one day after BMP2 induction using antibody against phosphoSMAD (PS) 1, 5, and 8. Studies conducted in a tracking mouse that contains a tamoxifen-regulated Wnt1-Cre recombinase crossed with a td Tomato red (TR) reporter (Wnt1(CreErt) :Ai9Tm) confirmed their neural origin...

BACKGROUND: The role of radiographs in the follow-up of patients with metal-on-metal hip resurfacing (MoMHR) implants is unclear. We investigated whether a combination of patient and radiographic factors predicted MoMHRs with evidence of a pseudotumor. METHODS: We performed a retrospective single-center case-control study of 384 MoMHRs. The pseudotumor group of 130 hips all had evidence of a symptomatic pseudotumor on cross-sectional imaging, with the diagnosis confirmed at revision...

OBJECTIVE Many reports have successfully demonstrated that cervical disc arthroplasty (CDA) can preserve range of motion after 1- or 2-level discectomy. However, few studies have addressed the extent of changes in segmental mobility after CDA or their clinical correlations. METHODS Data from consecutive patients who underwent 1-level CDA were retrospectively reviewed. Indications for surgery were medically intractable degenerative disc disease and spondylosis. Clinical outcomes, including visual analog scale (VAS)-measured neck and arm pain, Neck Disability Index (NDI), and Japanese Orthopaedic Association (JOA) scores, were analyzed...
