Arthroplasty in Femoral Head Osteonecrosis
Osteonecrosis of the femoral head is a destructive joint disease requiring early hip arthroplasty. The polyethylene-metal design using a 22-mm femoral head component, introduced by Charnley in 1950, has been widely used for over half a century. Since then, different materials with the capacity to minimize friction between bearing surfaces and various cement or cementless insert fixations have b...

متن کاملOsteonecrosis of the femoral head.
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.

متن کاملOsteonecrosis of the Femoral Head in Adults
Hospital Physician February 2008 13 O steonecrosis of the femoral head (ONFH) is a potentially debilitating condition of unclear etiology that affects up to 20,000 persons in the United States each year.1 ONFH in adults can be devastating as it typically occurs in a relatively young population (age, 35–40 yr). The disease is usually progressive,2 and without treatment, ONFH frequently results i...
متن کاملPrediction of femoral head collapse in osteonecrosis.
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. The analysis included a solution of the hip contact problem, which provided the contact pressure distribution, and subsequen...
