Avulsion-fracture of the anterior superior iliac spine with meralgia paresthetica: a case report.

Author information

Department of Orthopaedic Surgery, Kobe University Graduate School of Medicine, Kobe, Japan.


We present a rare case of avulsion-fracture of the anterior superior iliac spine with meralgia paresthetica in a 16-year-old male basketball player. He had sensory disturbance affecting his left lateral thigh 10 days after the injury. Tinel's sign was elicited on percussing the avulsed bony fragment of the anterior superior iliac spine. He underwent open reduction and internal fixation. The lateral femoral cutaneous nerve was noted to be entrapped by one third of the avulsed bony fragment. That fragment was removed, and the remaining portion was reduced and fixed with 2 screws. At week 6, the patient had returned to basketball playing without pain. At week 8, sensory distribution in the left lateral thigh had returned to normal.
