A 48-year-old right-handed male surgeon complained of finger numbness, pain, cramps and weakness of 2 years' progression, without improvement after 2 carpal tunnel corticosteroid injections and splinting. The patient was diagnosed with lacertus syndrome with Hagert's triad. Sensory collapse test was positive, but the sensations during the test were not consistent with the literature. Therefore, a sensory collapse test was performed in combination with electromyography; immediately following cutaneous stimulation, partial transient collapse in muscle tone was observed, without complete interruption. Following surgical release of the ipsilateral median nerve at the lacertus fibrosus, the symptoms were resolved, and combined sensory collapse test and electromyography revealed minimal to no collapse in muscle tone following cutaneous stimulation.
一位 48 岁的右利手男性外科医生主诉手指麻木、疼痛、痉挛和无力，进展 2 年，经 2 次腕管皮质类固醇注射和夹板固定后无改善。患者被诊断为 Hagert 三联征合并带长腱纤维鞘的正中神经卡压综合征。感觉崩溃试验阳性，但感觉在试验过程中与文献不一致。因此，进行了感觉崩溃试验结合肌电图检查；在皮肤刺激后立即观察到部分短暂的肌张力崩溃，但没有完全中断。对同侧带长腱纤维鞘的正中神经进行手术松解后，症状得到缓解，联合感觉崩溃试验和肌电图检查显示皮肤刺激后肌张力崩溃最小或无。
