Extensor Hallicus Longus (EHL) tendon lacerations with Dorsalis Pedis (DP) artery injuries are uncommon when present together. Insufficient literature exists regarding surgical management of these uncommon injuries. We present a case of a delayed presentation of a 29-year-old male who sustained a Zone 4 EHL laceration to the dorsal midfoot with concomitant DP artery pseudoaneurysm. Magnetic resonance imaging showed 5.5 cm diastasis between tendon stumps and Computed Tomographic Angiography confirmed a DP artery pseudoaneurysm. Co-case with Orthopedic and Vascular Surgery where Vascular Surgery performed DP artery excision and repair pseudoaneurysm and Orthopedic Surgery performed allograft reconstruction of the EHL tendon with a successful functional outcome at follow up. Given the paucity of literature on EHL injuries and no evidence of a reported concomitant EHL tendon laceration with DP artery pseudoaneurysm, we believe that this combined case can be used as a guide to help clinicians and patients in the clinical decision-making process.
