| Abstract: | Nonunion in the setting of chronic osteomyelitis after severe open ankle fractures is a feared outcome with severe loss in patient quality of life. Tibio-talo-calcaneal arthrodesis is a good salvage treatment option in this difficult patient cohort. We report a case of chronic osteomyelitis with severe destruction of the ankle joint after failed fracture fixation of an open trimalleolar ankle fracture. Fusion was ultimately achieved 5 years later using a novel-staged Masquelet technique with external ring fixator stabilization and bone graft reconstruction including femoral harvested autograft using reamer-irrigator-aspirator. This case shows that infection free arthrodesis of the ankle can be achieved even years after failed treatment. This procedure restored significant quality of life through pain relief and much improved mobility and may be a helpful technique in complex tibio-talo-calcaneal arthrodesis in the setting of chronic osteomyelitis and significant joint destruction. |
