Tibiotalocalcaneal arthrodesis using a femoral locking plate.

The goal of a tibiotalocalcaneal arthrodesis is to create a pain-free, stable hindfoot and ankle. Although a reserved procedure, it is useful when simultaneous ankle and subtalar joint pathology exists. Numerous complications have been reported after tibiotalocalcaneal arthrodesis, most importantly nonunion. Locking plates have proved to be a more stable construct than alternative forms of arthrodesis. In the inverted positions, the hybrid plating of the femoral locking plate structurally aligns with the anatomy of the hindfoot. This provides an anatomically sound construct, while allowing for both locking and lag screw insertion. We describe a new technique using a 4.5-mm condylar plate for tibiotalocalcaneal arthrodesis.
