Method for assessing functional outcome after total hip arthroplasty

摘要

A method of evaluating functional outcome after total hip replacement by computer tomography, characterized in that the CT examination is carried out in a volume of 1 transverse section at the level of the anterior-upper awns iliac bones and calculated atrophy coefficient (KA), expressed as the ratio of sums of products of the areas and densities studied healthy hand muscles to the sum of the products area and density of the studied muscle side of the disease, its reduction at 6 months after surgery ii compared to preoperative period of more than 0.2 is an additional objective criterion positive functional outcome THA, at the same time its decrease less than 0.1 is a prognostic indicator of the probable instability endoprosthesis components.
