| Popis: | During surgery for elbow fracture, wires and screws crossing the elbow from posterior to anterior place the brachial and ulnar arteries at risk for inadvertent penetration. The authors’ goal was to define the sagittal proximity of the brachial and ulnar arteries to the proximal ulna throughout an arc of elbow motion using dynamic fluoroscopy. The brachial artery was injected with barium in 10 fresh-frozen cadaveric elbows. Sagittal fluoroscopic images were obtained at elbow flexion angles of 0°, 30°, 60°, 90°, and 120°. Two measurements were obtained at each flexion angle: (1) the distance between the coronoid tip and the brachial artery and (2) the distance between the coronoid base and the ulnar artery. One-way analysis of variance was used to compare mean distances for each flexion angle within each measurement group. A coronal image identified the mediolateral course of the brachial artery. The distance from the coronoid tip to the brachial artery significantly increased with increasing flexion from 0° to 60° ( P P Orthopedics. 2015; 38(4):e253–e256.] |
