Abstract
- Selective posterior rhizotomies were carried out in 30 patients(mean age, 7 years) with cerebral palsy. The procedure involves lumbo-sacral laminectomy with stimulation of the rootlets from the second lumbar to the second sacral posterior roots on the involved side. Those rootlets showing abnormal EMG response with abnormal muscle contraction were cut under the surgical microscope. The mean follow-up period was 10 months. The outcome was evaluated with the preoperative and postoperative Peacock's grading system. All patients became improved in spasticity and 17(57%) patients improved in functional Peacock grading. The young and intelligent patients became more improved but, that was not significant stastically. The functional grade was stastically significant prognostic factor:The low functional group becom more improved. Longer follow-up is expected to show more improvement in functional grade.
