改良手术治疗脑瘫痉挛性双侧下肢瘫(英文)

Modified surgery for cerebral palsy of both lower extremities with spastic diplegia

[目的]2004年以来对重症脑瘫痉挛性双侧瘫治疗方法进行改进,探索提高其治疗效果的方法。[方法]23例重症脑瘫痉挛性双侧瘫。男14例,女9例;年龄3～12岁,平均5.7岁;主要症状:不能独自站立和行走,双下肢肌紧张,家长扶持站立,双下肢呈剪刀步态,双髋、膝关节屈曲,踝关节跖屈,双足马蹄内翻畸形,足尖着地行走。体格检查:双髂腰肌、内收肌、腘绳肌、小腿三头肌、胫前肌、胫后肌、长屈肌、趾长屈肌部分或多数不同程度肌张力增高。依Ashworth分级,为3～4级。治疗方法:对动态性肌痉挛,采用肌内肌腱切断或肌筋膜切断;对静态性肌痉挛行肌腱滑动延长,胫前肌腱劈开外侧1/2移位。然后用自制外固定器矫形固定,保持膝关节伸直,双踝、足中立位,双下肢外展30°,6周后去除外固定康复训练。[结果]本组病例随访1～3年,平均2.2年。优良21例,有效2例。[结论]严重脑瘫痉挛性双侧瘫,一期多关节软组织松解,肌力平衡,外固定矫形,术后配合家庭长期康复训练,是一种有效的治疗方法。

[ 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.
