Revascularization of digit ulcers by the "dorsalis pedis" or the
plantar artery was considered as DR.
Mourougayan [13] advocates the use of the medial
plantar artery instep flap as it can be raised as an island fasciocutaneous flap based on medial plantar vessels, with the branch of the medial plantar nerve supplying the instep skin and reaching the posterior-most part of the weightbearing surface of the heel with ease.
Blood supply arose from the posterior medial and the medial
plantar artery. Peritendinous blood vessels penetrated the tendon and anastomosed with the longitudinally oriented intratendinous network.
The lateral
plantar artery passes obliquely across the sole of the foot forming the plantar arterial arch that is completed by a deep branch from the dorsalis pedis artery (Standring; Moore et al, 2010; Kelikian & Sarrafian, 2011).
