Functional Evaluation of Gluteal Muscles according to Electromyography Data in the Patients with Supraacetabular Neoarthrosis

Abstract

The data of the study of the total EMG amplitude and deflections frequency of gluteal muscles in the patients with neoarthrosis depending on the severity of the contracture and type of articular interaction in the hip are given in the report. Prior to operative intervention low functional possibilities of gluteal muscles were defined at the side of neoarthrosis in elliptic character of articular interaction as well as in S-shaped one. After limb reconstruction the prognosis for restoration of pre-operative parameters of gluteal muscles was favorable for the patients with elliptic character of articular interaction. Functional and adaptive possibilities of m.Gluteus medius and m.Gluteus maximus were considerably reduced in the patients with S-shaped neoarthrosis after subtrochanteric supportive osteotomies of femur.
