title: Tibiocalcaneal Fusion for Charcot Ankle With Severe Talar Body Loss: Case Report and a Review of the Surgical Literature.
abstract: Severe bone loss resulting from talar body necrosis in the Charcot ankle can be challenging to treat. In particular, the Charcot ankle will demonstrate progressive instability and deformity, causing protrusion of the medial or lateral malleolus, which will mostly lead to skin ulcers or osteomyelitis and, in some cases, will ultimately require transtibial amputation. Problems such as bone fragility, poor compliance with load-bearing restrictions, susceptibility to infection, and circulatory disorders cause difficulties in the surgical treatment of the Charcot ankle. We believe that tibiocalcaneal fusion is a reliable method to obtain satisfactory outcomes in these difficult cases. However, no study has reported on the use of a locking plate for tibiocalcaneal fusion. Therefore, we report on tibiocalcaneal fusion using a locking plate in 3 patients with Charcot ankle and severe talar body loss. All patients achieved bony union with a plantigrade foot and without any skin complications. We have concluded that a locking plate provides rigid fixation and easier insertion of additional screws, when necessary.
