Abstract:
[Objective ] To investigate the improvement of the surgical treatment effect on cerebral palsy with spastic diplegia by performing modified surgeries since 2004. [Method ] Twenty-three cases of severe cerebral palsy with spastic diplegia were operated, 14 male, 9 female; age 3 ～ 12 years; the average age of 5.7 years; their main symptoms were unable to stand and walk independently, with severe hypermyotonia of both lower extremities, and a scissoring type of gait when standing, hip and knee flexing contracture, ankle and foot equinovarus. Physical examination: there was hypermyotonia of the iliopsoas, adductor musculus, hamstrings, triceps surae, anterior and posterior tibial muscle, flexor pollicis longus and flexor digitorum longus. The muscle tone was 3 ～4 grade according to Ashworth criterion. Treatment: The intramuscular tenotomy, fascial division or sliding elongation were performed, to lengthen the tendon of the joint flexion contracture, the lateral half of anterior tibial muscle tendon was transferred laterally to balance the muscle force at the foot. Finally, both lower extremities were fixed by a new designed external frame, to straigthen the articular genu, keep both ankles and feet in neutral position, both lower extremities abducting 30°, and to correct all joint deformities. Family rehabilitation programs started after the external frame was removed 6 weeks later. [Result] All cases were followed up in 1 ～3 years with the average 2. 2 years. The results were evaluated as excellent, good and ineffective, according to correction of the joint deformities, the ability to stand and walk, and parent's satisfaction to the treatment. Of them 21 cases were excellent, 2 cases good, and no ineffective case. [ Conclusion ] For the severe cerebral palsy with spastic diplegia in children, reasonable release of the tight tendons of the multi-joint flexion contracture, balance of muscle force at the foot, correction of all deformities and fixation of the lower extremities with the new external frame, and long term of family rehabilitation after the surgery, are more effective treatment.
