Traumatic Tibialis Anterior Muscle Herniation with a Large Fascial Defect Managed by Prolene Mesh Repair: A Rare Case Report.

Abstract

<h4>Introduction</h4>Tibialis anterior muscle herniation is an uncommon condition caused by a defect in the deep fascia, most frequently following trauma.<h4>Case report</h4>We report a rare case of a 22-year-old male who presented with symptomatic tibialis anterior muscle herniation 1 year after blunt trauma. Clinical examination revealed a reducible swelling over the anterolateral aspect of the right leg, becoming prominent on standing and muscle contraction. Intraoperatively, a large fascial defect measuring approximately 9 × 3 cm was identified.<h4>Conclusion</h4>The defect was successfully managed using a Prolene mesh for tension-free repair. At the 6-month follow-up, the patient was asymptomatic with no recurrence or complications. This case highlights Prolene mesh repair as a reliable option for large traumatic fascial defects.
