Atypical Femoral Fractures (AFF) represent fractures located between the lesser trochanter and the supracondylar flare of a femur. An increasing pool of evidence supports their association with the prolonged use of bisphosphonates, even though a direct correlation is yet to be proved. The purpose of this review is to encapsulate the current evidence associating bisphosphonate use and the development of AFFs, the clinical features related to their presentation, as well as to report the armamentarium of strategies available in the prevention and treatment of AFFs...

Introduction: Osteosynthesis of the femur using an interlocking nail is the gold standard for treating diaphyseal fractures of the femur. There are two established entry points for the antegrade interlocking nails which is the piriformis fossa or the greater trochanter. It has been reported that varus malalignment was frequently seen in proximal femur fracture which were treated with interlocking nail utilizing the greater trochanter entry point. The study was done to find out if the problem was of significance...

Dislocation after total hip arthroplasty (THA) remains a devastating complication and a primary cause for revision arthroplasty. Historical data indicate that a posterior approach is associated with a higher dislocation rate. In this study, we present a highly reliable and anatomical reconstruction, based on the biomechanical findings of a previous cadaveric experiment. The posterior soft tissues were repaired in 2 layers. First a reattachment of the posterior orbicular ligament is performed at the anterior capsule...

We report a man who underwent autologous stem cell transplantation (ASCT) for multiple myeloma. Two months after ASCT, he presented with necrotising cholecystitis due to gallbladder stones and was submitted to laparoscopic cholecystectomy. About a week later, he developed progressive skin ulcers at sites where trochanters had been inserted. Progressive enlargement and necrotic aspect of these ulcers took place despite debridement and large spectrum antibiotics. New ulcers developed at the site of enoxaparin injection at the right arm (pathergy phenomenon)...

Ischiofemoral impingement (IFI) is a rare cause of hip pain defined by a narrowing of the space between the lateral aspect of the os ischium and the lesser trochanter of the femur. Several underlying anatomic, functional and iatrogenic pathologies have been identified for symptomatic IFI in native hip joints and after total hip arthroplasty. Clinical symptoms vary but most commonly consist of pain of the lower buttock and groin including the inner thigh, and a snapping or clunking phenomenon is often reported...

Pressure ulcers develop in patients who endure long periods of immobilization, often caused by conditions such as musculoskeletal and neurological diseases. Pressure ulcers adversely affect the patient and increase caregiver burden and healthcare costs. Typical sites for these ulcers include the sacrum, trochanters, and heels; they also occur on the nape of the neck, penis, nostrils, helix of the ear, and upper back. Compression stockings are commonly used to prevent and stop the progression of venous disorders, including deep vein thrombosis, but their role in the development of pressure ulcers is not well known...
