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.
近年来，基于骨间前动脉和骨间后动脉及其在腕部的吻合支，已开发出多种局部皮瓣（例如骨间后皮瓣、旋前方肌皮瓣等）。供应皮瓣的动脉网络解剖结构在临床和解剖学文献中均已明确。大多数作者认同腕部骨间动脉之间吻合的恒定存在，且除皮瓣使用外不存在主要的解剖变异。在本研究中，基于对60个保存标本的尸体解剖，发现了骨间动脉的几种明显血管变异。最常见的类型是在前臂中1/3处骨间后动脉与骨间前动脉的一个穿支之间存在额外吻合，这种情况占20%。骨间前动脉掌侧支和背侧支形成环状的情况占5%。如先前所述，骨间前动脉背侧支穿过骨间膜的点变化范围较大。
