Pilon骨折的治疗进展

Advances in the Treatment of Pilon Fractures

摘要: Pilon骨折的治疗核心在于软组织优先原则与胫骨远端关节面精准解剖重建。分阶段治疗可以明显降低伤口感染率和提高临床疗效优良率，一期行胫骨骨折外固定/伤口封闭负压引流术，软组织稳定后二期切开复位内固定。手术入路根据损伤机制个体化：如内翻损伤选前内侧入路，外翻损伤用前外侧入路，跖屈位后柱损伤采用经腓骨骨折线间接复位，联合入路要求皮肤桥 ≥ 3 cm以降低并发症。负压封闭引流(vacuum sealing drainage, VSD)预防性应用使闭合骨折切口并发症率降至10%，切口过渡管理使75%病例免于皮瓣手术，开放创面感染率降至8.2%。内固定匹配生物力学需求：内侧接骨板抗内翻强度提升2.27倍，前外侧接骨板增强外翻稳定性，双钩锁定接骨板缩短手术时间15分钟。胫骨远端关节面严重粉碎性骨折后期创伤性关节炎的发生率仍达25%，未来需结合3D打印定制接骨板、AI制定术前计划、术后快速康复等来提升疗效。

Abstract: The cornerstone of Pilon fracture management lies in the soft tissue-first principle and precise anatomical reconstruction of the distal tibial articular surface. Staged treatment significantly reduces wound infection rates and improves clinical outcomes, involving initial external fixation and/or vacuum sealing drainage (VSD), followed by delayed open reduction and internal fixation (ORIF) after soft tissue stabilization. Surgical approaches are individualized according to injury mechanisms: anteromedial for varus patterns, anterolateral for valgus patterns, and posterolateral with open fibular fracture line technique for plantarflexion-induced posterior column injuries. A skin bridge ≥3 cm is recommended in combined approaches to minimize complications. Prophylactic negative-pressure wound therapy (NPWT) reduces incision complication rates to 10% in closed fractures, while transitional wound management obviates flap surgery in 75% of cases and decreases open wound infection rates to 8.2%. Internal fixation is biomechanically optimized: medial plating enhances varus resistance by 2.27-fold, anterolateral plates improve valgus stability, and double-hooked locking plates shorten operative time by 15 minutes. Despite these advances, the incidence of post-traumatic arthritis remains as high as 25% in severely comminuted fractures. Future integration of 3D-printed patient-specific plates, AI-based preoperative planning, and enhanced recovery protocols may further improve therapeutic efficacy.
