The extensor hallucis capsularis is an accessory extensor tendon with varied occurrence. Here, we present the case of a 40-year-old man with chronic extensor hallucis longus tendon rupture treated using extensor hallucis capsularis tendon as a double-bundle autograft. He had dropped a knife proximal to the right hallux metatarsophalangeal joint 4 months ago. Computed tomography revealed the presence of extensor hallucis capsularis, with its width and thickness, and the point of divergence from the extensor hallucis longus tendon. Because direct suturing was considered difficult and the extensor hallucis capsularis tendon was sufficiently wide and long, double-bundle autograft transplantation of extensor hallucis capsularis was performed. At 1-year follow-up examination, the patient retained almost full function of his hallux. To the best of our knowledge, this is the first case to use this technique. Using the extensor hallucis capsularis tendon for grafting should be carefully considered because the variable width and length may limit the graft strength. IV.
拇短伸肌囊状腱是一条出现情况各异的副伸肌腱。在此，我们报告一例40岁男性慢性拇长伸肌腱断裂病例，采用拇短伸肌囊状腱作为双束自体移植物进行治疗。患者4个月前在右拇趾跖趾关节近端掉落一把刀。计算机断层扫描显示存在拇短伸肌囊状腱，及其宽度、厚度以及与拇长伸肌腱的分叉点。由于认为直接缝合困难且拇短伸肌囊状腱足够宽且长，遂进行了拇短伸肌囊状腱双束自体移植。在1年的随访检查中，患者拇趾功能几乎完全保留。据我们所知，这是首例使用该技术的病例。使用拇短伸肌囊状腱进行移植应谨慎考虑，因为其宽度和长度的变异性可能会限制移植物的强度。 四、
