Three patients with a failed total ankle arthroplasty underwent tibiocalcaneal arthrodesis. In an attempt to preserve leg length, a titanium cage filled with autologous bone was placed in the defect. None of the ankles healed primarily. After 9 to 29 months, the cages, which only contained necrotic material, were removed and repeat arthrodesis was performed using a retrograde intramedullary nail. After this procedure, 1 ankle had healed after 14 months whereas 2 did not heal. However, after a third attempt, using external fixation, 1 of the latter 2 healed. The method used in this report cannot be recommended. Although titanium mesh cages filled with autograft have been successfully used to substitute for vertebral defects, the author does not feel that the method can be recommended for ankle arthrodesis.
三名全踝关节置换失败的患者接受了胫跟关节融合术。为了保留肢体长度，在缺损处放置了一个填充自体骨的钛笼。所有踝关节均未一期愈合。9至29个月后，取出仅含有坏死物质的钛笼，并使用逆行髓内钉进行再次关节融合术。此手术后，1例踝关节在14个月后愈合，而2例未愈合。然而，在第三次尝试使用外固定后，后2例中的1例愈合。本报告中使用的方法不推荐使用。尽管填充自体移植骨的钛网笼已成功用于替代椎体缺损，但作者认为该方法不适合踝关节融合术。
