Surgery for unstable hips in cerebral palsy

Area of Science:

• Orthopedic Surgery
• Pediatric Orthopedics
• Cerebral Palsy Research

Background:

• Unstable hips are a common complication in patients with total-body-involvement cerebral palsy.
• Previous treatments like soft-tissue release alone have shown high recurrence rates for hip dislocation or subluxation.

Purpose of the Study:

• To evaluate the effectiveness of different surgical techniques for managing unstable hips in cerebral palsy.
• To compare combined pelvic and femoral osteotomy with femoral osteotomy alone, both combined with soft-tissue release.

Main Methods:

• A retrospective study of 67 patients (86 hips) with total-body-involvement cerebral palsy.
• Surgical procedures included combined pelvic and femoral osteotomy with soft-tissue release, femoral osteotomy with soft-tissue release, and proximal femur excision.
• Radiographic assessment of migration percentage and center-edge angle was performed sequentially.

Main Results:

• Combined pelvic and femoral osteotomy and soft-tissue release demonstrated superior correction of hip instability compared to femoral osteotomy and soft-tissue release alone.
• Soft-tissue release as a standalone procedure was abandoned due to frequent recurrence of dislocation/subluxation.
• Excision of the proximal femur served as a viable salvage option for eroded femoral heads.

Conclusions:

• Combined pelvic and femoral osteotomy with soft-tissue release is an effective surgical approach for unstable hips in cerebral palsy.
• Surgical management requires careful consideration of technique based on hip pathology and radiographic parameters.
• Further research into long-term outcomes of these procedures is warranted.
