[Coexistent paralytic drop foot and gluteal fibrosis after intramuscular infections--therapeutic implications].

Six children with paralytic drop foot, which developed after intramuscular injections and who had co-existing gluteal fibrosis are presented in this study. Paralytic drop foot was diagnosed on an average of 5.5 months after intra-gluteal injections. This was the major therapeutic problem. The diagnosis of gluteal fibrosis was made on an average only 3 years and 7 months later. In 3 cases the external rotation and abduction contracture of the extremity in the hip joint, caused by gluteal fibrosis, with active plantar flexors and supinators of the foot could contribute to the recurrence of the equinovarus deformity of the surgically corrected foot.
