Use of the Antegrade Posterior Interosseous Artery Flap for Coverage of Complex Elbow Wounds

One of the most versatile soft-tissue flaps available for elbow coverage that is reliable, quick, and easy to perform, with minimal donor defect and without the sacrifice of a major blood vessel, is the antegrade posterior interosseous artery flap. A large amount of vascularized fascia can be dissected with the flap, and it can be useful in lining the elbow joint or any exposed implant(s). After flap harvest, the donor site is often amenable to primary closure or requires a simple skin graft for closure. This article explains the technique for harvesting an antegrade posterior interosseous artery flap and describes 10 cases in which the flap was used for complex soft-tissue defects of the elbow not amenable to local wound care or skin grafting.
