Primary transfer of extensor hallucis brevis tendon for repair of extensor hallucis longus tendon rupture

Abstract

Extensor hallucis longus tendon rupture can have a detrimental effect on gait and stability if not treated appropriately. While an end to end anastomosis is the preferred surgical technique, this is not always possible in neglected injuries due to tendon retraction. We present the primary transfer of the extensor hallucis brevis tendon as a viable alternative in cases of neglected extensor hallucis longus tendon ruptures. Due to the close proximity of the extensor hallucis brevis tendon and the preservation of its intended function in the foot, this allows for ease of repair of a difficult defect while maintaining tensile strength of the extensor hallucis longus tendon. Clinically, the patient was able to return to 100% pain free function within 5 months.
