Comparative analysis of the power indices of the lower extremity muscles in the patients after total endoprosthesis of the hip joint, depending on surgical access

Abstract

Objective. To compare the power characteristics of the lower extremity muscles after endoprosthesis of a hip joint in application of anterior-lateral and posterior-lateral surgical accesses. Materials and methods. Biomechanical investigation in accordance to electrotensodynamometry in 120 patients preoperatively, in early (in 3 weeks) and late (in 4 mo) period after endoprosthesis of a hip joint. Operative intervention was performed, using anterior-lateral operative access in 60 patients, and applying posterior-lateral - in 60 patients as well. Conclusion. There was established, that restoration of necessary muscular balance after endoprosthesis of a hip joint is guaranteed by application of anterior-lateral and posterior-lateral access, but the terms of restoration of muscles of various groups are differed.
