One year after rupture of the 5th flexor profundus tendon, a 45-year-old man showed signs of carpal tunnel syndrome. At surgery the proximal stump of the 5th flexor profundus tendon was found in the carpal tunnel. Due to an anomalous origin of the 4th lumbrical muscle from the profundus tendon of the 4th finger the proximal stump of the 5th flexor profundus tendon had withdrawn far proximally and in this way produced a carpal tunnel syndrome.
一名45岁男性在其第五指深屈肌腱断裂一年后出现腕管综合征症状。手术时发现第五指深屈肌腱的近端残端位于腕管内。由于第四蚓状肌起自第四指深肌腱的异常起点，第五指深屈肌腱近端残端向近端回缩较远，从而导致了腕管综合征。
