The integrity of the various structures within the feet depends on their blood supply. Lesions of the feet often require revascularization, which if successful avoids the need for amputation. To provide greater anatomical detail to aid vascular surgery and imaging, the anatomy and constitution of the deep plantar arch was studied in 50 adult cadaveric feet. the arteries of the foot were injected with red neoprene latex and dissected under magnification. the deep plantar arch, present in all feet, was the result of anastomosis between the deep plantar artery and the deep branch of the lateral plantar artery. the deep plantar artery was predominant in 72% of specimens (Type I arches) and the lateral plantar artery in 22% (Type II), with the contribution being equal in 6% (Type III). the medial plantar artery contributed to the medial segment of the deep plantar arch by its deep branch in 12% of specimens. the distance between the deep plantar arch and each interdigital commissure was generally constant, averaging 29% of total foot length. the deep plantar arch was located in the middle third of the foot in all specimens. being in the distal part of this third in 90%. the deep plantar arch is, therefore formed mainly by the deep plantar artery, a branch of the dorsal artery of foot: its location can be estimated if foot length is known.
