Pain posteriorly in the ankle can be caused by bony impingement of the posterolateral process of the talus. This process impinges between the tibia and calcaneus during deep forced plantar flexion. If this occurs it is called posterior ankle impingement syndrome. We report the case of 2 athletic monozygotic twin brothers with bony impingement posteriorly in the left ankle. Treatment consisted of ankle arthroscopy in both patients during which the symptomatic process was easily removed. At 3 months after surgery, both patients were completely free of pain, and 1 of the brothers had already returned to sports. The posterior ankle impingement syndrome is not a rare syndrome, but it has not been described in siblings thus far. That these 2 patients are monozygotic twin brothers suggests that genetics could play a role in the development of skeletal deformities that can result in posterior ankle impingement syndrome.
踝关节后方疼痛可能由距骨后外侧突的骨质撞击引起。在深度强迫跖屈时，该突起会在胫骨和跟骨之间受到撞击。如果发生这种情况，就称为后踝撞击综合征。我们报告了2例患有左踝后方骨质撞击的运动型同卵双胞胎兄弟的病例。两名患者均接受了踝关节镜检查，术中轻松切除了有症状的突起。术后3个月，两名患者均完全无痛，其中1名兄弟已经恢复运动。后踝撞击综合征并非罕见综合征，但迄今为止尚未在兄弟姐妹中被描述过。这两名患者是同卵双胞胎兄弟，这表明遗传学可能在导致后踝撞击综合征的骨骼畸形发展中起作用。
