Introduction: The Neurovascular Bundle (NVB) in the dorsum of the foot is likely to get injured during midfoot surgeries. Finding an anatomical landmark to identify this NVB is essential to prevent iatrogenic injury.

Aim: To identify an anatomical landmark to locate the Dorsalis Pedis Artery (DPA) and Deep Peroneal Nerve (DPN) in the dorsum of foot.

Materials and Methods: The relationship of this NVB to Extensor Hallucis Brevis Musculotendinous (EHBMT) junction was noted in dorsum of seventy feet. Correlation between the foot length and EHBMT junction length was determined.

Result: In 30 feet (42.85%), the DPN was medial to DPA and in 40 (57.14%), it was lateral to DPA. In two feet, the medial branch of DPN pierced the EHB proximal to the musculotendinous junction and in the remaining feet it passed behind EHBMT junction. There was a positive correlation between the foot length and the EHBMT junction length.

Conclusion: The EHBMT junction can be used as a reliable landmark to identify the DPN during the mid-foot surgical approaches.
