摘要
骨间后动脉,为前臂背侧皮瓣的营养动脉。我们对40侧前臂骨间后动脉,进行以下解剖学研究:①骨间后动脉分型。②在旋后肌下缘的骨间后动脉外径、长度和该动脉至肱骨外上髁的距离。③骨间后动脉行程与紧邻。以上研究对骨间后动脉各型作为前臂背侧皮瓣血管蒂修复手和前臂等缺损提供形态学依据。
The posterior interosseous artery (PIA) is the nutritive artery of the dorsal forearm flap. This article describes the dissection study for PIA in 40 cases. The results are as follows: 1. PIA is classified into different types; 2. the external diameter of PIA at the inferior margin of the supinator, the length of PIA and the distance between the artery and external epieondyle of the humerus are described; 3. the course of the artery and its neighboring structures are defined. The above study provides the foundation of designing of the posterior forearm pedicled flap in the repair of defects situated on the forearm and hand.
