Ankle cheilectomy as surgical treatment for anterior ankle impingement has high rates of procedural success and low rates of complications when performed before the onset of significant osteoarthritis. We present 3 patients who developed insufficiency fractures of the talar neck following cheilectomy for anterior ankle impingement. Due to the high risk of avascular necrosis associated with displaced talar neck fractures, the recognition of talar insufficiency fractures by the radiologist can aid in the timely diagnosis and initiation of intervention. Because radiographic findings of stress fractures often require weeks to manifest, maintaining a high index of suspicion in the postcheilectomy setting allows the radiologist to suggest appropriate further imaging when appropriate.
踝关节切骨术作为治疗前踝撞击症的手术方法，在严重骨关节炎发作前进行时，手术成功率高且并发症发生率低。我们报告3例因前踝撞击症行踝关节切骨术后发生距骨颈不全骨折的患者。由于移位的距骨颈骨折与缺血性坏死风险高相关，放射科医生识别距骨不全骨折有助于及时诊断并启动干预。因为应力性骨折的影像学表现通常需要数周才能显现，所以在踝关节切骨术后保持高度怀疑指数可使放射科医生在适当的时候建议进行适当的进一步影像学检查。
