Distal scaphoid excision is one treatment option for osteoarthritis of the scaphotrapeziotrapezoid (STT) joint following failure of conservative measures. Potential complications of this procedure include injury to the carpal ligaments, cartilage, and radial artery.
A single case was identified by the senior author, and the medical record was reviewed for surgical notes, progress notes, and radiographs.
A 68-year-old male sustained ruptures of the flexor digitorum superficialis (FDS) and flexor digitorum profundus to the index finger 3 years following a distal scaphoid excision for symptomatic STT osteoarthritis. He required a flexor tendon reconstruction using the remaining FDS tendon for graft incorporated with a Pulvertaft weave. His midcarpal pain continued after recovery of his index finger function, eventually requiring a 4-corner fusion of the wrist.
Flexor tendon rupture is a previously unreported complication of distal scaphoid excision for STT arthritis.
对于经保守治疗失败的舟月三角（STT）关节骨关节炎，舟骨远侧切除术是一种治疗选择。该手术的潜在并发症包括腕关节韧带、软骨及桡动脉损伤。
资深作者确定了1例病例，并查阅病历中的手术记录、病程记录及X线片。
一名68岁男性在因症状性STT骨关节炎行舟骨远侧切除术后3年，示指的指浅屈肌（FDS）和指深屈肌发生断裂。他需要使用剩余的FDS肌腱进行屈肌腱重建，并采用Pulvertaft编织法植入移植物。示指功能恢复后，他的腕中关节疼痛仍持续存在，最终需要进行腕关节四角融合术。
屈肌腱断裂是STT关节炎行舟骨远侧切除术之前未报道过的并发症。
