Closed rupture of the little and ring finger flexor tendons caused by the hamate is mostly associated with a fracture or nonunion of the hamate hook. Only one case of a closed rupture of the finger flexor tendon caused by osteochondroma in the hamate has been reported. Here, we present a case study to highlight the possibility of hamate osteochondroma as a rare cause of finger closed flexor tendon rupture based on our clinical experience and literature review.
A 48-year-old man who had been a rice-field farmer for 7-8 h a day for the past 30 years visited our clinic due to the loss of right little finger and ring finger flexion involving both the proximal and distal interphalangeal joints. The patient was diagnosed with a complete rupture of the ring and little finger flexors because of the hamate and was pathologically diagnosed with an osteochondroma. Exploratory surgery was performed, and a complete rupture of the ring and little finger flexors due to an osteophyte-like lesion of the hamate was observed, which was pathologically diagnosed as an osteochondroma.
One should consider that osteochondroma in the hamate may be the cause of closed tendon ruptures.
钩骨导致的小指和环指屈肌腱闭合性断裂大多与钩骨钩骨折或不愈合有关。仅有1例钩骨骨软骨瘤导致手指屈肌腱闭合性断裂的病例报道。在此，我们基于临床经验和文献回顾，通过一个病例研究来强调钩骨骨软骨瘤作为手指闭合性屈肌腱断裂罕见原因的可能性。
一名48岁男性，在过去30年里每天在稻田劳作7 - 8小时，因右小指和环指近端及远端指间关节屈曲功能丧失前来我院就诊。该患者因钩骨被诊断为环指和小指屈肌完全断裂，并经病理诊断为骨软骨瘤。进行了探查手术，观察到因钩骨类似骨赘的病变导致环指和小指屈肌完全断裂，病理诊断为骨软骨瘤。
应考虑钩骨骨软骨瘤可能是闭合性肌腱断裂的原因。
