Pectoralis Major Release to Improve Shoulder Abduction in Children With Cerebral Palsy

The aim of our study was to evaluate the surgical results after pectoralis major muscle release in children with cerebral palsy and to assess a caregiver's satisfaction in patient's care after this procedure.Twenty-one shoulders in 13 patients were analyzed at least 12 months after surgery. All but 1 patient involved in our study had quadriplegic type of cerebral palsy involvement. In 17 limbs, only pectoralis release was performed; in 4 limbs, latissimus dorsi release was added. After clinical examination, a questionnaire was used to determine the caregiver's assessment. The passive range of abduction and flexion was maintained at an angle greater than 90 degrees in 10 patients. External rotation was restricted in 6 patients. All caregivers would recommend this surgery to another patient. All but one reported improvement in care of the patients after surgery. The indication for this surgical procedure is limited only to the selected cerebral palsy cases in which custodial care is impaired by shoulder adduction contracture. The 2 main indications for the procedure are the limitations in the ability to bathe the axilla and the difficulty in dressing.
