Posterior talar body fractures are challenging with regards to optimal surgical approach, especially fractures involving the articular surface for which anatomical reduction is required. These fractures are often reduced surgically utilizing either the medial malleolus osteotomy (MMO), or posteromedial approach (PMA). While the MMO exposes the medial aspect of the body of the talus and avoids compromising the blood supply to the anterior talus through the deltoid ligament, it provides minimal access to the posterior process and to the posteromedial talar dome. Furthermore, by definition this approach results in iatrogenic damage to the articular cartilage and a trace loss of bone at the osteotomy site, which may preclude an anatomic reduction. The PMA on the other hand provides visualization of the entire posterior talus, including the posterior process and posterior aspect of the talar dome, thus it may indicated for appropriate reduction and visualization of fractures of these sites. This article describes the technique and reports on outcomes in the largest series of patients reported in the literature to our knowledge who sustained posterior talar body fractures that were managed through this approach.
距骨后体骨折在选择最佳手术入路方面具有挑战性,尤其是涉及关节面的骨折,这类骨折需要解剖复位。这些骨折通常采用内踝截骨术(MMO)或后内侧入路(PMA)进行手术复位。虽然MMO可以暴露距骨体的内侧,避免通过三角韧带损害距骨前部的血供,但它对后突和距骨后内侧穹窿的暴露有限。此外,从定义上讲,这种入路会导致医源性关节软骨损伤和截骨部位的少量骨质丢失,这可能会妨碍解剖复位。另一方面,PMA可以看到距骨后部的全貌,包括后突和距骨穹窿的后部,因此它可能适用于这些部位骨折的适当复位和可视化。本文描述了该技术,并报告了据我们所知文献中报道的采用该方法治疗距骨后体骨折的最大系列患者的治疗结果。
