Acute Reconstruction of Traumatic Zone IV Re-tear of Extensor Hallucis Longus Tendon using Extensor Hallucis Brevis loop Technique - A Mid-term Follow-up Case Report.

Introduction: The present case report describes an acute reconstruction of extensor hallucis longus (EHL) tendon with defect treated using looped extensor hallucis brevis (EHB) tendon graft.

Case Report: A 40 year male manual labor had an acute traumatic EHL tear which was repaired at a primary health care center. After 2 days, the patient felt a sudden click and a re-tear at zone IV of EHL. Since there was a defect of 3.5 cm which was not amenable for primary repair, EHB graft was used for the reconstruction in a loop fashion. The foot and ankle disability index score was 95.2 at 2 years follow-up with grade 4 + power.

Conclusion: EHB graft is a good alternative to other autografts for extensor hallucis longus reconstructions with good clinical and functional outcomes.
