Skeletal metastases are common in the adult population. The proximal femur is a frequently affected bone in the appendicular skeleton. The orthopaedic surgeon may be the first to find a pathologic lesion of the proximal femur and appropriate diagnosis and nonoperative management is essential prior to surgical treatment. Bisphosphonates and ...

The menisci have an essential function in force transmission across the knee. Injuries to the menisci are common. The indications for repair should be expanded, as the results of partial meniscectomy may deteriorate over time. Tears in younger, higher demand patients should be prepared to optimize the healing environment and ...

The glenohumeral joint is the most commonly dislocated joint in the body. The prevalence of this condition and the instability that may result from it has been a focus of diagnosis and treatment since the original description of the Bankart lesion in 1923. Now, with the introduction of MRI, lesions ...

Although ankle arthrodesis has been considered the gold standard for treatment of symptomatic end stage arthritis, recent improvements in arthroplasty designs and instrumentation have led to a resurgence in interest in ankle arthroplasty. While first generation arthroplasty systems had high failure rates due to cemented techniques or highly constrained designs, ...

Ankle sprain injuries are the most common injury sustained during sporting activities. Three-quarters of ankle injuries involve the lateral ligamentous complex, comprised of the anterior talofibular ligament (ATFL), the calcaneofibular ligament (CFL), and the posterior talofibular ligament (PTFL). The most common mechanism of injury in lateral ankle sprains occurs with ...

Despite operative reduction and internal fixation (ORIF), many patients who sustain proximal femur fractures develop posttraumatic arthritis. Conventional total hip arthroplasty (THA) in the setting of altered femoral morphology and retained hardware can be quite challenging. Hip resurfacing can provide a favorable option. The present report describes three patients in ...

Two important issues affecting the outcome of total hip arthroplasty have been dislocation and wear, despite excellent clinical results. Larger femoral heads have had success in decreasing dislocation rates; however, there are concerns regarding the subsequent use of thinner polyethylene liners, and their effects on wear rates. Historically, high stresses ...

Minimally invasive total hip arthroplasty (MIS THA) has recently increased in popularity. Concurrently, newly developed short femoral components are being used. These short components may make insertion during MIS approaches easier and preserve more bone than traditional femoral stems, while providing a more anatomic stress distribution in the proximal femur. ...

Intra-articular and extra-articular femoral Perthes deformities, or either, can result in severe alterations of the proximal femur and secondarily even involve the acetabulum, which can lead to premature osteoarthritis (OA) of the hip. In affected hips, joint damage due to impingement and instability may coexist. Classically, extra-articular impingement and associated ...
