[The role of computed tomography in dystrophic diseases of the hip joint].

Computer tomography data on 124 patients with degenerative-dystrophic diseases of hip joint of different etiology are presented. As indicated the results of investigations, computer tomography of hip joint is the effective method of early diagnosis of femoral head aseptic necrosis. Computer tomography application allows to detect precise location, size and character of the pathology process in hip joint and propose the optimal parameters of surgical correction. Femoral head densitometry in case of femoral head aseptic necrosis revealed the curves of two types: with unimodal and bimodal density distribution. Patients with bimodal histograms demonstrated worse results of surgical treatment.
