Modified adductor muscle transfer in cerebral palsy

Area of Science:

• Orthopedic surgery
• Pediatric orthopedics
• Cerebral palsy management

Background:

• Cerebral palsy (CP) often involves hip adductor spasticity, impacting gait and function.
• Surgical interventions like adductor release and transfer aim to improve hip abduction.
• Previous comparative studies are limited by confounding variables.

Purpose of the Study:

• To evaluate the efficacy and long-term outcomes of modified adductor transfers in cerebral palsy patients.
• To establish a reliable method for comparing adductor release and transfer procedures.

Main Methods:

• Retrospective follow-up of 141 patients with modified adductor transfers.
• Exclusion of patients with prior or concurrent hip surgery.
• Measurement of initial abduction gain and long-term maintenance of abduction.

Main Results:

• An average initial improvement in hip abduction of 43 degrees was achieved.
• Sustained abduction was maintained over time.
• A low incidence of recurrence was observed post-surgery.

Conclusions:

• Modified adductor transfer is an effective surgical option for improving hip abduction in cerebral palsy.
• Measuring surgical abduction gain and its maintenance is a more reliable comparison metric than radiographs or motor skills.
• This technique offers durable results with minimal recurrence.
