This article describes a novel technique for flexor digitorum profundus (FDP) avulsion injuries, useful for Leddy Packer type 3, 4, and 5 injuries. Multidirectional stability is achieved with combination pull-out suture, which neutralizes the deforming force of FDP, and cerclage wire, which holds the bone fragment in an anatomic position and provides interfragmentary compression. Traditional techniques such as interosseous wires, Kirschner wires, or plating risk fragment comminution and loss of reduction due to proximal pull of FDP as demonstrated in this case report of failed Kirschner-wire fixation. The technique presented here eliminates the risk of avulsion fragment comminution and provides stable fixation that allows for early mobilization.
本文介绍了一种用于指深屈肌（FDP）撕脱伤的新技术，适用于Leddy Packer 3型、4型和5型损伤。通过联合使用拔出缝线（可抵消FDP的变形力）和环扎钢丝（可将骨块固定于解剖位置并提供骨折块间加压）实现多向稳定性。如本克氏针固定失败的病例报告所示，诸如骨间钢丝、克氏针或钢板等传统技术存在骨折块粉碎及因FDP近端牵拉导致复位丢失的风险。本文介绍的技术消除了撕脱骨折块粉碎的风险，并提供稳定固定，允许早期活动。
