Severe bone defects pose a clinical challenge in total ankle arthroplasty (TAA) and are frequently considered contraindicated. We introduce an innovative approach that utilizes a structural tibial cut autograft to address anterior distal tibia bone defects during TAA. This technique is a viable alternative to employing revision TAA systems or resorting to excessively high tibial cuts. Furthermore, it facilitates achieving favorable sagittal alignment and ensures adequate fixation strength of the tibial component.
严重的骨缺损在全踝关节置换术(TAA)中构成了临床挑战,通常被认为是禁忌证。我们介绍了一种创新方法,即在 TAA 中使用结构性胫骨切取自体移植物来解决前远端胫骨骨缺损。与使用翻修 TAA 系统或采用过高的胫骨截骨相比,该技术是一种可行的替代方法。此外,它有利于实现理想的矢状面对线,并确保胫骨部件具有足够的固定强度。
