A retrospective review was conducted on 50 children with cerebral palsy, having
89 femoral varus osteotomy at an average age of 7.4 years, trying to identify
risk factors for complications, particularly redislocation and avascular
necrosis. Among the well-reduced hips, new subluxation developed in 12 cases;
postoperative radiographic measurements showed a mean neck-shaft angle of 135
degrees and an acetabular slope of 32 degrees . Main risk factors for secondary
dislocation seem to be insufficient correction of preexisting valgus and
uncorrected acetabular dysplasia. Avascular necrosis was observed in 33 hips
(37%): 26 minor and seven severe. Older age at surgery and high preoperative
Reimer's migration index seem statistically significant risk factors.
