Osteonecrosis of the Femoral Head

Journal of the American Academy of Orthopaedic Surgeons, 1999
New cases of osteonecrosis of the femoral head in the United States number between 10,000 and 20,000 per year. This disease usually affects patients in their late 30s and early 40s. Although a number of authors have related specific risk factors to this disease, its etiology, pathogenesis, and treatment remain a source of considerable controversy. This

Osteonecrosis of the Femoral Head

Orthopedic Clinics of North America, 2019
Osteonecrosis of the femoral head most commonly arises from trauma or corticosteroid and alcohol use but is also associated with blood dyscrasias and metabolic and coagulation disorders. Initial evaluation includes a history and physical examination and plain radiographs. Early-stage osteonecrosis is best evaluated by MRI.

Fracture of the Femoral Head

Journal of the American Academy of Orthopaedic Surgeons, 2007
Fracture of the femoral head is a severe, relatively uncommon injury; typically, it occurs following traumatic posterior dislocation of the hip joint. The Pipkin classification is the most commonly used classification system. Diagnosis is aided by a complete history, physical examination, and imaging, including computed tomography.

Femoral Head Fractures

JBJS Reviews, 2015
Femoral head fractures are consequential but uncommon injuries. Because of their relatively rare occurrence, large series with validated outcomes have not been published, to our knowledge. However, the available literature provides important insights into the treatment of these challenging fractures.

The sphericity of the femoral head

Medical & Biological Engineering, 1967
Ten femoral heads, three of them grossly pathological, have been examined to determine their shape, employing seven types of testing. We found the sagittal section of the normal femoral head to be remarkably circular, with very close concentricity of the surface of the articular cartilage and the underlying bone.

The femoral head notch

Skeletal Radiology, 1987
A notch-like defect at the vertex of the proximal femoral ossification center is a normal variant in children. This has often been mistaken for Legg-Perthes disease. This sharply defined defect is distinct from the irregular epiphyseal ossification patterns common in other areas.
