Тhe diagnosis of articulate surface changes of coxofemoral joint in coxarthrosis patients by spiral computer tomography

The objective was to study changes of an articulate surface (AS) of coxofemoral joints (CFJ) at patients with osteoarthrosis (OА), using СТ Methods. The group of patients (92 joints), suffering bilateral OА 2nd and 3rd radiological stage was tested by СТ. The width of AS in front, anteromedial, posterolateral, back sides was measured; thus joints of all patients have been preliminary divided in two groups: group (A) with uniform narrowing of an articulate surface and group (B) with nonuniform narrowing AS. Comparison of sizes and areas of joint space in different parts was performed.
