Abstract

Background: The deep peroneal nerve is one of the nerves often examined in clinical practice and is used in flaps that need to preserve sensation, such as the free flap of the dorsalis pedis to cover soft tissue defects in the hand or big toe flap and second finger flap in transferring the thumb to the hand. Currently, research around the world on the positional correlation between the deep peroneal nerve and the dorsalis pedis artery is limited and there is no consensus among authors on its quantitative anatomy and branching pattern. Objective: Describe the course and position of the deep peroneal nerve relative to the dorsalis pedis artery. Methods: Study design to report a series of cases performed on 15 cadavers (30 lower limb) immersed in formol with lower extremities intact, not dissected at the Department of Anatomy - University of Medicine and Pharmacy, Ho Chi Minh City. Results: The present study recorded five positions of the medial branch of the deep peroneal nerve relative to the dorsalis pedis artery. Type I: Deep peroneal nerve positioned medial the dorsalis pedis artery has the highest occurrence rate of 63.3%, type II: Deep peroneal nerve positioned lateral the dorsalis pedis artery has an occurrence rate of 6.7%. type III: The deep peroneal nerve lies just above and covers the dorsalis pedis artery at a rate of 6.7%, type IVa: The deep peroneal nerve crosses the dorsalis pedis artery from the lateral to the median in 20%, type IVb: The deep peroneal nerve crossing the dorsalis pedis artery from median to lateral has the lowest occurrence rate of 3.3%. Conclusion: Understanding anatomical variations in the course of the deep peroneal nerve helps maximize the therapeutic effectiveness and minimize the unanticipated complications of any clinical practices involving the deep peroneal nerve by inferring from its anatomical knowledge.
