Single-Stage Correction of Severe Rigid Ankle Equinus Deformity by Talectomy and Tibiocalcaneal Fusion in Adulthood: A Case Report

INTRODUCTION: Equinus deformity is commonly seen in children with underlying diseases such as arthrogryposis multiplex congenita congenita, spina bifida, and myelomeningocele. It is the most common deformity of the lower limb following poliomyelitis in the developing countries. The equinus deformity may be accompanied with varus (equinovarus), cavus (equinovarus) or cavus, and varus (equinocavovarus). If the deformity is not treated in early childhood, it becomes progressive, rigid, and difficult to treat. CASE REPORT: In this article, we describe a case of 35-year-old lady who had severe rigid equinus deformity due to poliomyelitis. We did talectomy and tibiocalcaneal fusion to achieve single-stage correction of the deformity. At 2 years follow-up, patient had painless plantigrade foot and satisfactory esthetic and functional outcome. CONCLUSION: Severe rigid ankle equinus deformity in adults can be corrected by midfoot osteotomies and/or gradual correction using external fixator. When the patient is not compliant for gradual correction technique, the deformity can be corrected by talectomy and tibiocalcaneal fusion. The purpose of presenting this case report is to demonstrate and share satisfactory outcome of single-stage talectomy and tibiocalcaneal fusion.
