3D-Printed Brace Utilization for an Isolated Fibular Head Fracture: A Case Report

Isolated fibular head fractures are rare and often result from direct trauma to the lateral knee or varus stress. These fractures, accounting for a small percentage of fibular fractures, can be challenging to diagnose on initial imaging. We present a case of a 65-year-old man who sustained a blow to the right fibular head from a cow's kick. Initial X-rays were inconclusive, but an MRI revealed an impacted fibular head fracture. The patient was managed conservatively with a 3D-printed brace, a walking boot, and crutches for mobility support. The brace, made of carbon fiber nylon with a thickness of 4 mm, was secured using an elastic bandage and rubber adhesive. It provided lateral stability and pressure to the tibial head, improving the patient's perceived stability while walking. The patient recovered fully without complications. Unlike fractures of the distal fibula, which often require surgical intervention, fibular head fractures rarely need surgery and can be managed effectively with conservative measures. This case highlights the value of advanced imaging and customized 3D-printed bracing in managing isolated fibular head fractures.
