[Radiologic signs of aseptic necrosis of the femoral head in adults and their pathomorphologic substrate].

The examination of 284 patients with aseptic necrosis of the head of the femoral bone (ANHFB) has revealed that tuberculosis coxitis in adults erroneously diagnosed in 74.6%. Four X-ray stages of ANHFB which meet the requirements of diagnosis, differentiation, surgical treatment have been identified. The average periods of their development have been defined. A pathomorphological substrate of X-ray film and variants of the disease course are described in the paper. It is stated that to make a X-ray diagnosis of ANHRB should include indications of a process stage, which facilitates its correct diagnosis.
