Hip Jint Endoprosthesis Replacement in Patient With Dysplastic Coxarthrosis With a Background of Congenital Hip Dislocation Using Subtrochanteric Shortening Osteotomy

Abstract

Hip joint endoprosthetics is one of the most common methods of treating patients with dysplastic coxarthrosis often accompanied by plenty of technical difficulties, both at the stage of preoperative planning and directly during the surgery. This issue is caused by pronounced anatomical and biomechanical changes in joint on the background of dysplasia together with difficulty in positioning the components of endoprosthesis and risk of traction injury to the sciatic nerve when bringing down the proximal femur. This article presents clinical experience of treating patients with dysplastic coxarthrosis associated with congenital hip dislocation using subtrochanteric shortening osteotomy. Postoperative follow-up of patients after 3, 6 and 12 months and assessment of the life quality according to the Harris Hip Score and SF-36 questionnaires demonstrated good long-term treatment results, absence of postoperative complications, restoration of supporting function of the operated limb and improvement in life quality of the patients under study. The results of clinical observation were supplemented by analysis of current medical periodicals with the aim of recommending this treatment method for traumatologists and orthopedists performing similar operations in patients with hip joint dysplastic osteoarthrosis.
