Surgical approaches to the dorsum of the foot are common for management of midfoot fracture dislocations and arthritis. The anatomy can be difficult to identify and neurovascular injury can be a serious complication. Extensor hallucis brevis (EHB) is a consistent and easily identifiable structure encountered in these approaches. This study assesses the close relationship of the EHB musculotendinous junction to the neurovascular bundle for use as a reliable landmark. The relationship of the medial branch of the deep peroneal nerve (DPN) in the dorsum of the foot to the EHB tendon was examined by dissection of ten adult cadaveric feet preserved in formalin. Using a dorsal approach, the anatomy of the DPN neurovascular bundle was studied relative to its neighbouring structures. Local institutional review board approval was obtained.Introduction
