The island sensate ulnar artery flap for reconstruction around the elbow.

Elbow joint prostheses have now become reliable and provide stable movement. Some do have rather sharp edges on the ulnar component which, particularly in the rheumatoid arthritics and the elderly, may erode the skin, leading to exposure. Various flaps will provide cover to this area but do tend to re-ulcerate, probably due to inability to appreciate excess pressure. The ulnar artery flap, including the medial cutaneous nerve of the forearm, provides durable and sensitive cover, preventing re-exposure. Its successful use in two cases is described.
