Results of Muscle Release for the Dislocation of the Hip in Cerebral Palsy

Abstract

Hip dislocation of cerebral palsied children cause ambulatory children unstable of gait and non-ambulatory children impairment of dairy life.
Muscle releases (adductors, gracillis, psoas, rectus femoris and hamstrings) were performed in our hospital for the patients whose hips tended to be disloced.
Results of these muscle releases are reported in this paper.
The patients who were performed only muscle releases after 1983 in our hospital are examined. AHI and CE-angle are applied for roentgenographic estimations.
Patients are 21 cases (38 hips) and the average age at the operation is 8 years old (5-14 years old). The 14 hips, were improved after operation and 24 hips were unchanged. Secondary operation were done for 5 cases. It is revealed that although roentgenographic improvement is minimal, functional improvements such as stability of gait or daily management are found in many cases.
