Introduction: Traumatic herniation of the leg muscle is not an uncommon condition. This may be a direct traumatic hernia caused by open injury to the leg, or an indirect traumatic hernia following blow to a contracted muscle causing rupture of the fascia and its consequent herniation. Tibialis anterior muscle herniation has been reported to be the most common form of muscle hernia of the lower extremities.Materials and Methods: We report on 3 cases of traumatic herniation of the tibialis anterior muscle who were treated using a periosteal rotation flap raised from the anteromedial aspect of the tibia and used to close the fascial defect. Conclusions:We have found this to be a safe surgical procedure in the adult and adolescent age group with satisfying results and reduced recurrence rate and postoperative complications.
