Proximal Tibial Epiphyseal Injury in a 14‐Year‐Old Asian Male With Vitamin D Deficiency as a Possible Cause: A Case Report

We report a case of a 14‐year‐old Asian male who presented with a Salter–Harris Type II injury of the proximal tibial epiphysis and a fibular fracture following a minor mechanism of injury. The patient was emergency transported to our hospital with complaints of pain and flexion deformity around the left knee following a contusion. Imaging studies confirmed the diagnosis of a Salter–Harris Type II injury of the proximal tibial epiphysis. Given the minor mechanism of injury, blood tests revealed vitamin D deficiency. Under general anesthesia, manual reduction and percutaneous pin fixation were performed, resulting in good bone union and functional recovery. This case highlights the importance of considering vitamin D status when managing pediatric fractures following minor mechanisms of injury or unusual fractures and epiphyseal injuries.
