A 25-year-old paraplegic man who had sustained a T3/T4 vertebral compression fracture 3 years previously presented with severe, painful spasm of the left hamstring muscle group of 2 hours' duration. This spasm produced extreme knee flexion of a degree which held the left foot posterior to the right buttock. An intravenous injection of 2 g magnesium sulphate produced immediate relief. Possible mechanisms of action of magnesium are discussed.
一名25岁的截瘫男性，3年前发生T3/T4椎体压缩性骨折，现因左侧腘绳肌群严重疼痛性痉挛就诊，痉挛持续2小时。这种痉挛导致膝关节极度屈曲，使得左脚位于右臀部后方。静脉注射2克硫酸镁后症状立即缓解。文中讨论了镁的可能作用机制。
