The talus is a bone uncommonly affected by avascular necrosis (AVN) [1]. Factors such as trauma and pre-existing inflammatory arthropathy (particularly with concomitant steroid use) increase the risk of development of AVN. We report a case of resolution of Stage I AVN, diagnosed clinically and on magnetic resonance imaging (MRI), treated successfully by percutaneous core decompression of the talus. An MRI 12 weeks post-operatively showed complete resolution of the appearances of AVN.
距骨是一种很少发生缺血性坏死 (AVN) 的骨骼[1]。创伤和先前存在的炎症性关节病(特别是伴有皮质类固醇使用)等因素会增加 AVN 发展的风险。我们报告了一例临床和磁共振成像 (MRI) 诊断为 I 期 AVN 的病例,通过经皮距骨芯减压成功治疗。术后 12 周的 MRI 显示 AVN 的表现完全消失。
