According to the combined procedures and the effects of surgical manipulations, two groups were evaluated. The results of release of the adductor longus and gracilis without anterior obturator neurectomy were satisfactory when combined with proximal release of medial hamstrings. Hypertonicity in hip adduction was relieved. In cases of loss of function of the adductor brevis with anterior obturator neurectomy, the results were not satisfactory, and hyperabduction of the hip was inadequate. The adductor brevis plays an important role in stability of the hip. © Lippincott-Raven Publishers.
