Suggested risk factors are acetabular retroversion, obesity, latitude, hyperactivity, and coagulopathy. The most commonly applied classification is based on radiolucency in the lateral pillar of the femoral head, which i...

Aim. To develop an animal model of femoral head aseptic necrosis for studying Legg–Calvé–Perthes disease. Materials and Methods. induce the development necrosis, we used Wistar rats (n = 8) which suffered from combined hypoperfusion increased intra-articular pressure in hip joint. Having employed isoflurane anesthesia, performed incision (≈ 3 cm length) on outer surface thigh projection joint t...
