The Extraosseous and Intraosseous Arterial Anatomy of the Adult Elbow *(dagger)

Abstract

Our findings demonstrate that arterial contributions to the intraosseous circulation of the elbow are more specific than previously appreciated. The intraosseous circulation of the elbow is derived mainly from perforating vessels that arise from neighboring extraosseous arteries. These perforating arteries may be damaged by trauma or by extensile dissection during reconstruction of the elbow. An understanding of the extraosseous and intraosseous circulation of the elbow may help to avoid iatrogenic injury to the intraosseous circulation.
