Внесуставной болевой синдром после первичного протезирования тазобедренного сустава

Abstract

Objective: to determine the dynamics of the extra-articular pain after primary hip replacement. Materials and methods. A total of 1286 patients undergoing primary total hip arthroplasty. Among the patients were women, mean age was 56.6 ± 13.9 years. In a clinical study of patients using differential diagnostic table extra-articular pain, visual analogue scale of pain, with instrumental examination – X-ray data, and sonographic densitometry study. Results. The incidence of the disease state is 42.7 %. Risk factors for decompensation classified muscles that stabilize the hip joint (r = 0.78), shortening of the operated limb more than 3 cm (r = 0.72). The most intense pain is fixed from the 3 rd to the 6 th month after the surgery. The least pronounced dynamics of reduction in pain severity observed in patients with dysplastic coxarthrosis and diseases arising on a background of systemic pathology. Conclusion. Extra-articular pain occurs more than a third of patients after primary prosthesis. According to the etiology is often vertebrogenic and adaptive pain. From the 3 rd to the 6 th month, in connection with the formation of a new dynamic stereotype of gait is highest probability of occurrence and/or enhance the intensity of the pain, which are reduced to 12 th month after surgery.
