We report two cases of pronator teres syndrome (bilateral in one case) diagnosed in our Department by electromyographic studies during the last three years. The infrequency of this syndrome (1 case/201 cases of carpal tunnel syndrome), combined with the unspecified and inconsistent symptomatology (tenderness over the pronator teres, paresthesias and weakness of flexor pollicis longus, abductor pollicis brevis and opponens pollicis) frequently induced diagnostic mistakes. The electromyographic study is very useful showing a delay in proximal motor latency of the median nerve, diminution of motor nerve conduction in the proximal forearm segment of this nerve with normality of distal motor latency and sensory latency. Corticoid infiltration is the treatment of choice keeping in reserve surgery only for resistant cases.
我们报告了过去三年在我们科室通过肌电图检查诊断出的两例旋前圆肌综合征(其中一例为双侧)。该综合征发病率较低(每201例腕管综合征中有1例),再加上其症状不明确且不一致(旋前圆肌压痛、拇长屈肌、拇短展肌和拇对掌肌感觉异常及无力),常常导致诊断错误。肌电图检查非常有用,可显示正中神经近端运动潜伏期延迟,该神经在前臂近端节段的运动神经传导减弱,而远端运动潜伏期和感觉潜伏期正常。皮质类固醇浸润是首选治疗方法,仅对耐药病例保留手术治疗。
