[Applied anatomic study of the posterior interosseous artery in forearm]
Abstract:
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 epicondyle 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.
