Abstract：
Anatomical variations of the extensor pollicis longus (EPL) tendon are rare. Variations are typically asymptomatic, yet knowledge of these variations poses significance in the setting of dorsal approaches to wrist surgery. We present a case of an accessory EPL tendon that was discovered intraoperatively in the fourth dorsal compartment during open repair of a distal radius fracture with a dorsal spanning plate. If not correctly identified, the accessory EPL could have been entrapped beneath the plate, resulting in limited thumb extension and potentially tendon rupture.
摘要：
长伸肌腱（EPL）肌腱的解剖变异很少见。变异通常是无症状的，然而，对这些变化的了解在手腕手术的背侧入路的设置中具有重要意义。我们介绍了一个附件EPL肌腱的病例，该病例是在使用背侧跨接板对桡骨远端骨折进行开放式修复期间在第四背侧隔室中发现的。如果没有正确识别，附件EPL可能被困在盘子下面，导致有限的拇指延伸和潜在的肌腱断裂。
