ARTERIAL VARIATIONS OF THE FOREARM

During the medical student’s training in the Anatomy we have studied the arterial constitutions of the forearm in 100 bodies from the Laboratory of the Descriptive Anatomy of the Medical School, University of Athens. On our efforts to classify the complexity of the forearm concerning its blood supply we accepted that we might have some basic groups that can be explained by the embryology. Our results were: A. “Regular” hematosis of the forearm (with the presence of the radial, the ulnar and the interosseous artery): 81% All the forearm’s arteries ramify from the brachial artery: 68% All the forearm’s arteries ramify from the superficial brachial artery: 7% The radial artery origins from the superficial brachial artery, the ulnar and the interosseous arteries from the brachial artery: 4% As in 3 with a wide osculation between the brachial and the radial artery in the elbow: 2% B. Forearm’s superficial arteries: 10% The superficialulnar artery substitutes the ulnar artery: 4% Superficial middle artery: 2% Superficial radial artery in addition to the normal radical artery: 2% The forearm’s superficial artery is short and ends at the forearm’s proximal part: 2% C. Presence of the middle artery (embryo remnant): 9% The middle artery origins from the ulnar artery with the interosseous artery: 3% The middle artery origins from the ulnar artery far from the common interosseous artery: 2% The middle artery origins from the common interosseous artery: 2% The middle artery origins from the radical artery: 2%
