[Coxarthroses due to ischemia. Ischemic coxarthropathy].
In the first part of their work, the authors present radiological, histopathological and experimental results showing that cartilage of the joint can be originally damaged by articular ischemia. In the second part, they analyze the clinical and radiological features of 40 cases of ischemic coxarthrosis, substantiated by histological examination: these are chronic coxarthropathies with changes in the cartilage without rupture of the femoral head but with medullary necrosis and often trabecular necrosis involving the head and the neck of the femur. These ischemic coxarthroses are most often well centered with a superior or supero-internal pinching and show few osteophytes. They constitute a group of coxarthrosis called "primitive", involving the structure because of a previous weakening of the cartilage.
