Acetabular augmentation for progressive hip subluxation in cerebral palsy
Journal of Pediatric Orthopedics
|August 1, 1984
Summary
Acetabular augmentation effectively treated hip instability in cerebral palsy patients. The procedure improved hip stability and the center edge angle, with good outcomes in most cases.
Area of Science:
- Orthopedic Surgery
- Pediatric Orthopedics
- Reconstructive Surgery
Background:
- Progressive hip instability is a common complication in patients with cerebral palsy.
- This condition can lead to pain, functional limitations, and further joint damage.
Purpose of the Study:
- To evaluate the effectiveness of acetabular augmentation in treating progressive hip instability in cerebral palsy patients.
- To assess changes in hip stability, center edge (CE) angle, range of motion, and postoperative complications.
Main Methods:
- Retrospective review of 20 acetabular augmentations in 17 cerebral palsy patients between 1969 and 1981.
- Average follow-up of 41.5 months.
- Evaluation included hip stability, CE angle, range of motion, and complications.
Main Results:
- Nineteen out of 20 hips achieved stability.
- The mean CE angle improved significantly from -17 degrees preoperatively to 50 degrees postoperatively.
- Eighteen hips were rated good, one fair, and one poor.
Conclusions:
- Acetabular augmentation is an effective surgical option for progressive hip instability in cerebral palsy.
- The procedure leads to significant improvement in hip stability and radiographic parameters.
- Potential complications, such as supracondylar femur fracture, should be considered.
