评价伴膝强直步态的脑瘫患儿行股直肌转移术的长期疗效。通过步态分析对 2 4例患儿的 38个受累下肢术前和术后 1年的功能状况进行评价 ,并于平均术后 4 .6年对 18例患者的 2 6个受累下肢进行功能状态评定 ,使用Hoffer’s行走标准对功能性活动状况进行评价。随访 1年时 ,最大摆动相膝屈增加 9.8° ,膝关节活动范围增加 7°,而站立时膝伸展有少量丧失。在最后步态分析时 ,摆动相膝屈的改善得以维持 ,但膝关节活动范围的增加有所减小。时间参数没有显著变化。长期随访时认为股直肌转移术后摆动相膝屈的增加与膝伸丧失有关。站立相屈膝过度患者可能需要做绳肌延长术。
To evaluate the long-term effect of rectus femoris muscle transfer in pediatric cerebral palsy with ankylosis. The gait analysis was used to evaluate the functional status of 38 affected lower extremities in 24 children with 1-year preoperative and 1-year postoperative follow-up. A mean of 4.6 postoperatively, 26 patients were involved in functional status Assessments of functional activity using Hoffer’s walking criteria. At 1-year follow-up, the maximal swing knee flexion increased by 9.8 °, the knee flexion range increased by 7 °, and a slight loss of knee extension occurred while standing. In the final gait analysis, the improvement of swing knee flexion was maintained, but the range of knee flexion was reduced. Time parameters did not change significantly. In long-term follow-up, it is considered that the increase of knee flexion and extension after rectus femoris is related to the loss of knee extension. Hypertension over standing patients may need to do hamstring extension.
