Acetabular Fracture and Triradiate Cartilage Injury in an Adolescent After a Motorcycle Crash: A Case Report

The acetabular triradiate cartilage is the main structure that determines the development of the acetabulum. Furthermore, the paucity of data in the literature and lack of consensus amongst physicians following diagnosis regarding whether to treat these fractures operatively or non-operatively places the physician with a challenging choice. Here, we report a case of a 13-year-old boy who suffered a triradiate cartilage fracture from a high-energy motorcycle crash and presented with a displaced, left T-type acetabulum fracture. The fracture was successfully treated surgically with open reduction and internal fixation (ORIF). At one year postoperatively, the patient has returned to daily activities, including noncontact sports, with no pain.
