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.

Osteonecrosis of the Femoral Head

Journal of the American Academy of Orthopaedic Surgeons, 2014
Osteonecrosis of the femoral head may lead to progressive destruction of the hip joint. Although the etiology of osteonecrosis has not been definitely delineated, risk factors include corticosteroid use, alcohol consumption, trauma, and coagulation abnormalities.

Osteonecrosis of the femoral head and pregnancy

Clinical Rheumatology, 1982
The authors report 7 anatomo-clinical cases of osteonecrosis of the femoral head, the clinical onset of which occurred during pregnancy or in the fortnight after delivery. On the basis of histological data obtained through core-biopsy in these 7 cases they discuss the relationship between osteonecrosis and reflex sympathetic dystrophy of the hip.

MANAGEMENT OF OSTEONECROSIS OF THE FEMORAL HEAD

Orthopedic Clinics of North America, 1997
Osteonecrosis of the femoral head continues to pose a therapeutic challenge to orthopedic surgeons. This pathologic process results from the death of living components of bone from mechanical and biologic factors. Diagnosis, clinical symptoms, and classification systems are discussed.

Revascularization of the Femoral Head in Osteonecrosis

Journal of the American Academy of Orthopaedic Surgeons, 1998
Osteonecrosis of the femoral head accounts for as many as 18% of total hip arthroplasties performed in western countries. The young age of affected patients and the potentially poor outcome have sparked an interest in alternative treatment modalities. Extracapsular placement of a vascularized fibular graft in the subchondral region of the femoral head ...

Hemiresurfacing for femoral head osteonecrosis

The Journal of Arthroplasty, 1987
A modified THARIES femoral resurfacing component was used as a hemiarthroplasty in 11 young adult patients (12 hips) with osteonecrosis. The mean follow-up period was 39 months (range, 24-62 months). In all of the hips, the necrosis had advanced to the stage of subchondral femoral head fracture and segmental depression, but there was a relatively ...

Stem cell therapy for osteonecrosis of the femoral head

Expert Opinion on Biological Therapy, 2005

Nontraumatic Osteonecrosis of the Femoral Head

The Journal of Bone & Joint Surgery, 2006
The etiology of osteonecrosis of the hip may have a genetic basis. The interaction between certain risk factors and a genetic predisposition may determine whether this disease will develop in a particular individual. The rationale for use of joint-sparing procedures in the treatment of this disease is based on radiographic measurements and findings ...

OSTEONECROSIS OF THE FEMORAL HEAD

The Journal of Bone and Joint Surgery. British volume, 1997
We performed a prospective study using MRI to evaluate early necrosis of the femoral head in 48 patients receiving high-dose corticosteroids for the treatment of various autoimmune-related disorders. The mean interval from the initiation of corticosteroid therapy to the first MRI examination was 2 months (0.5 to 6).
