title: [Clinical anatomy of the interosseous arteries of the forearm].
abstract: In recent years, several local flaps have been developed, based on the anterior and posterior interosseous arteries and their anastomoses at the wrist (e.g. posterior interosseous flap, pronator quadratus flap etc.). The anatomy of the arterial network supplying the flap is well established in both clinical and anatomical literature. Most authors agree in the constancy of the anastomoses between the interosseous arteries at the wrist and the absence of major anatomical variations excluding the use of the flap. In the present study, which is based on cadaver dissections of 60 preserved specimens, several gross vascular variations of the interosseous arteries have been found. The most frequent types were an additional anastomosis between the posterior interosseous artery and a perforating branch of the anterior interosseous artery in the middle third of the forearm, which was found in 20%. Ring-formations of the palmar and the dorsal branch of the anterior interosseous artery occurred in 5%. The point of perforation of the interosseous membrane by the dorsal branch of the anterior interosseous artery was found to vary in a larger extent, as described previously.
