Introduction: Subtalar dislocations are a rare injury, comprising 1–2% of all large joint dislocations and 15% of all peri-talar injuries. Most subtalar dislocations are managed acutely, with the documented reconstruction of chronic dislocations rare. This case report aims to present our experience with the first documented use of an Ilizarov frame for bony and soft tissue reconstruction in a case of chronic subtalar dislocation. Materials and methods: A single patient surgically treated for chronic subtalar dislocation was followed over a 2-year period, and retrospectively reviewed. Results: A 67-year-old lady presented with an over 10-year history of worsening ankle pain and significant varus deformity with skin contractures, limiting ambulation over the past 6 months. Computed tomography confirmed medial dislocations of the subtalar and talonavicular joints with head and neck fractures of the talus and generalized osteoarthritis. A two-stage reconstruction involving an Ilizarov frame and subsequent arthrodesis allowed for correction of soft tissue and bone with the return of independent ambulation. Conclusion: Although the correction of bony deformities is important in reconstruction, soft tissue management is crucial and must not be overlooked. An Ilizarov frame is ideal for correction of both the bony deformity and soft tissue contractures. Arthrodesis can be performed when the overlying soft tissue is able to accommodate correction of the varus deformity and reduction of the dislocations. While an Ilizarov frame requires both an experienced surgeon and a motivated patient, in the right hands, good functional recovery can be returned.
