Knee arthrodesis after infected tumor mega prosthesis of the knee using an intramedullary nail for callus distraction.

摘要

BACKGROUND: Infected tumor endoprosthesis of the knee in young patients can prove to be challenging. Common procedures are debridement and prosthesis reimplantation, amputation, revision arthroplasty, and arthrodesis. CASE PRESENTATION: We report the case of a 44-year-old man treated by arthrodesis followed by callus distraction after removal of an infected tumor mega prosthesis (Kotz type). Callus distraction was performed over a distance of 11 cm in 4 months using a femorotibial intramedullary nail with an external traction rope-winch system. METHODS AND FOCUS: The clinical, radiological, technical, and therapeutic features are discussed.
