Flexor tendon injury is a rare, but serious, complication after volar plate fixation for distal radius fractures. The plate position and prominence at the watershed line are contributing factors that cause flexor tendon injury. With the standard volar approach, the pronator quadratus (PQ) is typically elevated off the radial attachment. The distal part of the plate is often visible after repair of the PQ. We describe a "PQ-splitting" technique for covering the distal edge of the plate if primary PQ repair cannot completely cover the distal part of the plate. We also report the outcome of our series. This method can potentially prevent direct gliding of flexor tendons on the distal part of the plate and prevent flexor tendon attrition on the plate prominence.
屈肌腱损伤是桡骨远端骨折掌侧钢板固定术后一种罕见但严重的并发症。钢板在分水岭线处的位置和突出是导致屈肌腱损伤的因素。采用标准掌侧入路时，旋前方肌（PQ）通常从桡骨附着处掀起。修复PQ后，钢板远端通常可见。我们描述了一种“PQ劈开”技术，用于在初次PQ修复不能完全覆盖钢板远端时覆盖钢板远端边缘。我们还报告了我们系列病例的结果。这种方法可能会防止屈肌腱在钢板远端直接滑动，并防止屈肌腱在钢板突出处磨损。
