Bone Reconstitution With Synthetic Bone Graft Material for Osseous Defects in Revision Total Ankle Arthroplasty:

摘要

Category:Ankle ArthritisIntroduction/Purpose:Various treatments have been suggested for the treatment of periarticular cysts in revision total ankle arthroplasty including autograft and allograft bone grafting, polymethylmethacrylate cement, and revision to ankle or tibiotalocalcaneal arthrodesis. This study investigated the rate of osseous reconstitution following treatment with a unique calcium phosphate-calcium sulfate blend.Methods:A retrospective review of all revision total ankle arthroplasty procedures over a 3 year period was performed. 37 patients were identified that had utilized the calcium phosphate-calcium sulfate blend for the treatment of osseous defects. Data on graft location, volume, infection rate, bone reconstitution rate, and further revision procedures were collected. Plain radiographs were used to determine osseous reconstitution, qualified as bony trabeculae present with no lytic area remaining. Patient's average age was 66 years old, revision performed an average of 9.5 years afte...
