Adductor release in nonambulant children with cerebral palsy
Insights
Adductor release surgery effectively prevents hip dislocation in nonambulatory children with cerebral palsy, though those with significant preoperative hip coverage loss face higher risks. Unilateral procedures can negatively impact the contralateral hip.
Area of Science:
- Orthopedics
- Pediatric Surgery
- Cerebral Palsy Research
Background:
- Nonambulatory children with cerebral palsy are at high risk for spastic hip dislocation.
- Early intervention is crucial to prevent severe hip complications.
Purpose of the Study:
- To evaluate the effectiveness of adductor release and anterior obturator neurectomy in preventing hip dislocation.
- To identify risk factors for hip deterioration after surgical intervention.
Main Methods:
- Retrospective review of 86 hips in 50 nonambulatory children with cerebral palsy.
- Radiographic analysis of migration percentages preoperatively, early postoperatively, and at final follow-up.
Main Results:
- Adductor release prevented hip dislocation in 80% of cases, avoiding further surgery.
- Preoperative hip coverage less than 50% increased the risk of femoral head coverage deterioration.
- Unilateral adductor release negatively affected the nonoperated hip's stability.
Conclusions:
- Adductor release is a valuable surgical option for preventing hip dislocation in at-risk children with cerebral palsy.
- Careful patient selection, considering preoperative hip coverage, is essential for optimal outcomes.
- The potential contralateral effects of unilateral procedures warrant consideration.
Abstract:
Historically, nonambulatory children with cerebral palsy represent a "group at risk" for spastic hip dislocation. We reviewed the effectiveness of adductor release and anterior obturator neurectomy in treating 86 hips at risk in 50 nonambulatory children. Results were judged by comparing the migration percentages measured on the preoperative, early postoperative, and final postoperative radiographs. Adductor release succeeded in preventing hip dislocation and obviating the need for further surgery in 80% of cases. Patients with preoperative uncoverage exceeding 50% were found to be at greater risk for deterioration of femoral head coverage despite adductor release. Unilateral adductor release had a negative effect on the nonoperated hip.
