Complex ankle arthrodesis with step-cut osteotomy in Charcot arthropathy with bone loss.
We report a case of a complex limb salvage ankle arthrodesis in a patient with Charcot arthropathy. A step-cut osteotomy was performed in order to tackle the issues of anterior tibial bone loss; worsening leg length discrepancy; soft tissue contraction; joint instability and high risk of non-union. The construct formed by the step-cut allowed for the preservation of good bone stock; avoidance of further limb shortening; increased torsional stability and increased surface area for bony union. This resulted in a patient with a stable, plantigrade foot appropriate for footwear. We use this case to highlight this technique as an option in the operative management of complex ankle fusions with sagittal or coronal plane deformity with bone loss and subluxation of the ankle joint.
