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
