Avulsion fracture of tibial spine: A case report and review of literature

Fracture of the tibial spine is an uncommon injury, with an incidence estimated at 3:1,00,000 children per year. Sports and bicycling are the usual activities resulting in this fracture. The anterior spine is fractured many times more than the posterior. We are reporting a case of a 12-year-old female who presented with complaints of pain and swelling over left knee after falling from bicycle. Plane radiography and computed tomography scan showed tibial spine fracture with anterior cruciate ligament avulsion. Closed method was tried but reduction can not be achieved, finally open reduction and internal fixation done using 18 G stainless steel wires. Intraoperative movements of knee checked and fixation was found stable. The patient recovered progressively without any clinical signs of joint instability and returned to the same sport activity level that they had before the fracture.
