  • Title: Adolescent Segond fracture with an intact anterior cruciate ligament.
    Author: Reddy D, Alexander R, Hussain WM, Leland JM.
    Journal: Orthopedics; 2012 Jul 01; 35(7):e1112-5. PubMed ID: 22784911.
    Abstract:
    Segond fractures, or avulsion fractures of the proximal lateral tibial plateau, have been well documented and studied since their original description in 1878. Segond fractures have a widely recognized pathognomonic association with anterior cruciate ligament (ACL) injuries and often prompt orthopedic surgeons to consider reconstruction following radiographic and clinical evaluation. Adolescent patients are particularly vulnerable to these fractures due to the relative weakness of their physeal growth plates compared with the strength of their accompanying ligamentous structures. This article describes a case of a 13-year-old boy who sustained a Segond fracture that was not coupled with an ACL avulsion or tear. The patient sustained a twisting injury to his knee. He presented to the emergency room with an effusion and radiographic findings consistent with a Segond fracture. On follow-up examination 1 week after injury, the ACL was intact. The patient was followed for 5 months of conservative treatment. At final follow-up, the patient had reestablished his previous level of activity. This article describes the history, physical examination, and radiographic findings necessary to care for patients who present with a Segond fracture. Although considered pathognomonic for an associated ACL injury, this article describes a Segond fracture that occurred in isolation.
