Abstract

Entrapment of the extensor indicis proprius (EIP) after open reduction and internal fixation (ORIF) of the distal ulna with a plate and screw construct is rare. By literature review, we found evidence of such complication associated with distal radius fracture, but no past reports relating to the distal ulna. ORIF of the distal ulna is a common procedure for both fracture treatment and deformity correction. Due to the EIP muscle originating primarily from the dorsoradial surface of the distal ulna and the adjacent interosseous membrane, the muscle may be damaged or compressed by a fixation plate during ORIF, resulting in entrapment. We present two case reports of this rare complication, describing the method of clinical diagnosis, surgical treatment, and outcome. Our accompanying cadaver dissection provides an explanation for proper plate positioning during ORIF of the ulna to reduce the risk of EIP entrapment.

摘要

用钢板和螺钉构造对尺骨远端进行切开复位和内固定（ORIF）后，很少会捕获指伸肌（EIP）。通过文献综述，我们发现了与桡骨远端骨折相关的并发症的证据，但过去没有关于尺骨远端的报道.尺骨远端ORIF是骨折治疗和畸形矫正的常用方法。由于EIP肌肉主要来自尺骨远端的背背表面和邻近的骨间膜，在ORIF期间，肌肉可能会被固定板损坏或压缩，导致诱捕。我们提供了两种罕见并发症的病例报告，描述临床诊断的方法，手术治疗,和结果。我们伴随的尸体解剖为尺骨ORIF期间正确定位板提供了解释，以降低EIP截留的风险。
