[Biomechanical evaluation of the functional state of the locomotor system and the effectiveness of surgical treatment of children with Legg-Perthes disease].

Abstract

For the first time in the patients with Perthes' disease (stages II-III) the authors have evaluated the functional state of the locomotor system in dynamics on the basis of a complex study which included a roentgenobiomechanical analysis of the loads on the hip joint (39 children) after F. Pauwels technique (1959), radio pelvimetry (75 children) after Kh. Z. Gafarov et al. (1984) and biomechanical and electromyographic (36 children) in the static position and during walking. The results obtained have allowed to make a substantial contribution into the characteristics of the functional state of the hip joint in Perthes' disease and to make an objective evaluation of the efficacy of the surgical treatment consisting in using new methods with the aim of decompression and distraction on the basis of not only anatomic but also functional and biomechanical criteria of evaluation.
