Recently, there has been increased documentation of periarticular arthritis in the ipsilateral mid and hindfoot joints in long term follow-up of patients with prior ankle arthrodesis. This has led some surgeons to convert ankle arthrodesis to a total ankle arthroplasty which is contraindicated if the lateral malleoli is sacrificed. This paper describes a fibular-sparing Z-osteotomy surgical technique that is designed to preserve the anatomy of the ankle joint while providing excellent exposure to correct preexisting deformity and allow rigid stable fixation. This report describes the fibular-sparing Z-osteotomy that is technically easy and safe.
