【 摘 要 】

Category:Ankle ArthritisIntroduction/Purpose:Most current total ankle arthroplasty (TAA) designs attempt minimal bone resection and depend on bone ingrowth for long term survival. The arthritic process may cause subchondral bone cysts (SBCs), which could influence the available bone stock of the already limited distal tibia and talus. The prevalence or pattern of SBC formation in ankle arthritis has not been described. Furthermore, the ability of standard radiographs identifying and quantifying SBC formation is unknown. The purpose of our study is to define the prevalence and patterns of periarticular SBCs in the arthritic ankle and determine the efficacy of radiographs to identify SBCs. We hypothesized that the prevalence of SBCs is greater than determined from radiographs and that SBCs often extend beyond standard cuts for some TAA implants.Methods:We identified patients who presented with end-stage ankle arthritis and had pre-operative weight bearing x-rays and CT or MRI. Demographic data was obtained ...
