Surgery in spastic lower extremities among cerebral palsy is reserved for patients with a reasonable chance to ambulate, to correct the spastic deformity and to improve gait. This study aims to assess the local results of various soft tissue operations such as adductor tenotomy, hamstring release, tendon of Achilles lengthening and tendon transfers. From December 1989 to January 1992, twenty one cerebral palsy children were included in this study. Preoperatively, two of these 21 patients were freely ambulatory. After surgery, 14 were free ambulators and 7 were crutch walkers. These results showed that soft tissue surgery is effective. Combined with intensive physical therapy, optimum ambulatory function of spastic cerebral palsy patients can be achieved. (Author)
