【摘要】 目的通过对128例拇外展功能受损患者的病例统计,列出常用手术方法,并通过比较得出不同方法的使用频率及结果优劣。方法按动力、伤因、神经损伤部位、神经损伤数及有无肌腱移植,进行列表统计,以找出规律。并强调了转移肌腱的方向应与拇短展肌轴线方向一致。结果术后经长期随访,环指屈指浅肌、掌长肌、尺侧伸腕肌等应用最多,平均优良率为87.2%,小指外展肌、屈拇短肌等例数较少,但效果很好,值得推广。结论各种伤因所致正中神经损伤及大鱼际肌损伤,均可导致拇指外展功能障碍,只要腕关节及腕掌关节被动活动良好,有良好的动力来源,就应考虑肌腱移位手术,修复拇指外展功能。更多还原

【Abstract】 Objective To statistically analyze the 128 cases of thumb abductor defects and evaluate the commonly used operative methods. Methods Statistical analysis and evaluation were done in regard to the muscle strength, injury cause, injured parts, injured nerves and tendon transfer. Results We found by following up after the operation: FDS, PL, ECU were the most commonly used operative methods and their average excellent and good rate was 87.2%. Abductor digiti quinti and flexor pollicis brevis were less used but their effects were good. Conclusion When the median nerve of thenar is injured, the abductor of the thumb will be damaged. We should restore its function by tendon transfer as long as the muscle strength remains and the passive motion of the carpometacarpal joint is good.更多还原
