Isolated posterior malleolar fracture is a rare condition, and this fracture is usually overlooked and diagnosed as an ankle sprain owing to a lack of awareness and difficulty in diagnosis. Posterior ankle impingement syndrome (PAIS) is relatively common in athletes and is usually caused by trauma or overuse. The impingement occurs due to repeated compression of a bony or soft tissue. Here, we report a rare case of a 17-year-old rugby player presenting with posterior ankle impingement caused by nonunion of an isolated posterior malleolar fracture. This patient was treated using a posterior ankle arthroscopic excision. At 16 weeks postoperatively, his ankle and hallux pain disappeared, and he returned to sports activities with no morbidities related to the surgical procedure. Based on a computed tomography scan, the bone fragment causing the impingement was resected, and the union of the residual posterior malleolar fragment was verified.
单纯后踝骨折是一种罕见的病症，由于认识不足和诊断困难，这种骨折通常被忽视并被诊断为踝关节扭伤。后踝撞击综合征（PAIS）在运动员中相对常见，通常由创伤或过度使用引起。撞击是由于骨组织或软组织反复受压所致。在此，我们报告一例罕见病例，一名17岁的橄榄球运动员因单纯后踝骨折不愈合导致后踝撞击。该患者接受了后踝关节镜下切除术治疗。术后16周，他的踝关节和拇趾疼痛消失，恢复了体育活动，未出现与手术相关的并发症。基于计算机断层扫描，切除了导致撞击的骨碎片，并证实了残留后踝碎片的愈合。
