Transphyseal Femoral Neck Fracture in a Twenty-Month Old Male Child

Transphyseal femoral neck fractures are an extremely rare event, mainly occurring in children subjected to an significant traumatic force. The diagnosis is usually suggested by clinical examination with radiographic confirmation. Management varies; however, no consensus exists as to proper treatment. Intervention is primarily focused on the prevention of avascular necrosis (AVN) of the femoral epiphysis. We present the case of a 20-month-old male with a delayed diagnosis of transphyseal femoral neck fracture. X-ray (XR) and computed tomography (CT) scan images were used for diagnosis, to track healing, and monitor the possible emergence of avascular necrosis. Final imaging demonstrated full healing without AVN at two years. This study demonstrates the successful treatment of a rare pediatric fracture type with possible life-changing complications. Reduction, surgical fixation with K-wires, and spica casting are demonstrated as being acceptable treatment in the very young transphyseal fracture patient.
