Osteonecrosis of the Femoral Head
2020Osteonecrosis of the femoral head (ONFH) is a refractory disease caused by the disruption or impairment of blood supply to the femoral head. It is followed by the death of osteocytes and bone marrow as well as subsequent bone repair, which in turn leads to the structural changes and collapse of the femoral head, and joint dysfunction. Since Munro first

OSTEONECROSIS OF THE FEMORAL HEAD [PDF]
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).

Hemiresurfacing for femoral head osteonecrosis
The Journal of Arthroplasty, 1987A 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 ...

Cyclosporin A and osteonecrosis of the femoral head.
The Journal of Bone & Joint Surgery, 1987A vascular osteonecrosis has occurred in 5 to 40 per cent of patients who have undergone transplantation of a kidney and generally has been considered to be a complication of the use of corticosteroids. Currently cyclosporin A is in general use for its immunosuppressive property, so that a lower dose of corticosteroids is needed.

Osteonecrosis of the Femoral Head
2017Management of osteonecrosis of the femoral head is dependent on the stage of the disease and if there is collapse of the femoral head. Nonoperative management is rarely indicated, whereas core decompression with grafting can be a successful treatment method if used prior to collapse of the femoral head. For cases where subchondral collapse has occurred,

Osteonecrosis of the Femoral Head
Journal of the American Academy of Orthopaedic Surgeons, 2014Osteonecrosis 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 extending into the femoral neck
Skeletal Radiology, 2012Osteonecrosis of the femoral head (ONFH) is an ischemic disorder that can lead to femoral head collapse and secondary osteoarthritis. Although the condition is usually limited to the femoral head, we report a rare case of biopsy-proven ONFH extending into the femoral neck, which required hip replacement surgery.

Prediction of Femoral Head Collapse in Osteonecrosis [PDF]
Journal of Biomechanical Engineering, 2005 The femoral head deteriorates in osteonecrosis. As a consequence of that, the cortical shell of the femoral head can buckle into the cancellous bone supporting it. In order to examine the buckling scenario we performed numerical analysis of a realistic femoral head model.

Posttraumatic Osteonecrosis of the Femoral Head
2014The lifetime incidence of hip trauma is about 23.3 % in males and 11.2 % in females [1, 2]. Major complications of hip traumas include nonunion, malunion, and osteonecrosis. Posttraumatic osteonecrosis, which is reported in a range of 4.8–52.9 %, ultimately leads to arthritis unless diagnosed in the initial stage [3, 4].

Management of osteonecrosis of the femoral head
The Bone & Joint Journal, 2020AimsEarlier studies dealing with trends in the management of osteonecrosis of the femoral head (ONFH) identified an increasing rate of total hip arthroplasties (THAs) and a decreasing rate of joint-preserving procedures between 1992 and 2008. In an effort to assess new trends in the management of this condition, this study evaluated the annual trends ...
