title: [Effects of surgery on muscles on clinical and radiographic findings in the hip joint region in cerebral palsy patients].
abstract: PURPOSE OF THE STUDY Isolated or combined surgical procedures on muscles around the hip joint are currently indicated by many authors. In cerebral palsy patients they are regarded as essential intervention. MATERIAL In the years 2005-2007, surgery in the hip joint region was essential for 150 children between 3 and 18 years of age. At the time of surgery, the patients' locomotion ranged from stage 1 to stage 7 of the Vojta system. METHODS The outcome was evaluated by clinical and radiographic examination at 2 and 6 months post-operatively and hip migration percentage and Wiberg's CE angle were measured. RESULTS The best clinical and radiographic outcomes were achieved in children younger than 6 years of age. On the other hand, isolated transfer of the distal rectus femoris muscle significantly affected pelvis anteflexion in adolescent patients. The most marked decrease in migration percentage was found after adductor tenotomy combined with surgery on the iliopsoas muscle (55.6 %) or when the two procedures were combined with distal rectus femoris transfer. DISCUSSION Combined surigical procedures, i.e., adductor tenotomy, surgery on the iliopsoas muscle or rectus femoris muscle and medial hamstrings, with fixation using an abduction modified Atlanta brace, are effective in patients with marked lateral hip migration who are younger that 6 years. Isolated adductor tenotomy and distal transfer of the rectus femoris muscle markedly improve standing position in walking patients. CONCLUSION An appropriate combination of surgical procedures on muscles in the hip region and on medial hamstrings can significantly improve the patient's locomotion and, if lateral migration is present, help to avoid surgery on bones.
