尺侧腕屈肌移位重建屈肘功能

１９８１年５月～１９９２年１１月，连续应用尺侧腕屈肌移位重建屈时功能２１例。经平均３．８年随访，肘关节屈伸活动度最小为７０°，最大为１２０°。肌力最小达Ⅲ级，最大达Ⅴ级。全部病人能满足日常生活工作需要。讨论了在屈时功能重建的同时，需从上肢整体功能考虑肩关节的稳定性及前臂旋转功能。分析了影响疗效的因素，包括肱三头肌肌力不足致伸肘障碍；尺侧腕屈肌肌力小于Ⅳ级者，重建的屈肘活动度较小；肩关节不稳定影响屈肘肌的力量；以及康复治疗的重要性等。提出了相应的提高疗效的措施。

ABSTRACTSFLEXOR CARPI ULNARIS MUSCLE TRANSFER TO RESTORE ELBOW FLEXION

wenty-one cases with injurys of upper trunk of brachial plexus in 18 and poliomyelitis in 3were treated by transfer of flexor carpi ulnaris muscle to restore flexion of elbow from may, 1981through November, 1992. There were 16 males and 5 females with an average age of 28 years old(ranged 17-60 years). All of the patients was combined with incompetence of abduction function ofshoulder, 6 cases with incompotence of extenxor function of elbow and 11 cases with incompotence ofsupifiation function of farasem. The potients were followed from, 1 to 6 years (averaged 3. 8 3 years)followtng operation. The range of active motion of the elbow after traatment was 70 to 120 degrees(zaro to 90 degrees in one, to 100 degrees in 3, to 110 degrees in 2, to 120 degrees in 6 . and 10 to90 degrees in 4, 10 to 110 degrees in 2, 10 to 120 degrees in 2 and 40 to 110 degrees in one). Themuscle strength of elbow flexion after operation was 3 in 3rd degrees , 9 in 3rd to 4th degrees . 8 in 4thdegrees and 1 in 5th degrees. Authors suggested that the stability of shoulder and the rotation functionof the farearm shoud be reconstructed similtaneously. The factors influencing the surgecal results andmethods of improving the long term results were disscused.
