Fibular head avulsion fractures are rare injuries determined by traction of the fibular attachment of the lateral collateral ligament (LCL). Surgical treatment is often recommended with different techniques such as tension band fixation or lag screws stabilization. In this article, we describe a fixation technique of fibular head fractures obtained through the use of anchors. A 45-year-old athletic patient came to our attention in our traumatologic service after a motorcycle accident. He reported a complex injury of the posterolateral corner with an avulsion fracture of the left fibular head. We performed a clinical evaluation at the final follow-up visit (six months). We demonstrated that the use of suture anchors may be an effective technique of fixation in avulsion fracture of the fibular head associated with combined posterolateral corner injuries.
