【 摘 要 】

Category:Ankle, SportsIntroduction/Purpose:Abnormalities in the tibial plafond geometry, such as varus deformity or insufficient talar anterior coverage, have been recognized as the congenital risk factors of chronic ankle instability (CAI) and eventual osteoarthritis (OA) development. Given that the gutter articulations are playing a substantial role in ankle stability, presumably, geometrical abnormality of these articulations also increases such risks, though this concept has not been well addressed to date. Our recent study (2016 AOFAS Annual Summer Meeting) revealed that OA ankles are frequently (>50%) marked by excessive anterior and/or inferior opening of the talar side-walls. The present study examined whether or not CAI cases share these geometrical characteristic, so as to identify a risk factor that predispose ankles to CAI and eventual OA development.Methods:Clinical multi-detector computed tomography (MDCT) images, from 29 symptomatic CAI cases who were indicated for surgical repair or recons...
