ABSTRACT
Hip dislocation in the spastic form of cerebral palsy is mainly unilateral, leading to pelvic deformities, appearance of scoliosis, difficult positioning when seated, as well as pain experienced during walking and standing. Tenotomies of adductor muscles were performed in 22 patients (44 hips), 14 male and 8 female. In 12 patients decrease in migration percentage was noted, the average patient age being 5,4 years. In 10 patients no changes in migration percentage were detected, compared to preoperative values. Mean age of the latter group was 7,2 years. The results of the operative procedures were considered good, since the regular follow-up radiographies (done every 6 months) showed decrease in migration percentage. Adductor muscle tenotomies should be performed in incipient hip dislocations with migration index not overcoming 30%, preferably at younger age.
