The arterial supply around the elbow joint consists of an intricate network of vessels that form crucial anastomoses, ensuring consistent blood flow during joint movement. These vascular connections provide essential collateral circulation that maintains tissue perfusion even during various arm positions and potential vessel occlusion. Understanding this complex network is vital for orthopedic surgeons, vascular specialists, and clinicians managing upper extremity conditions.
Anatomical Labels and Descriptions
A. Profunda Brachii The deep artery of the arm that originates from the brachial artery. This vessel provides crucial blood supply to the triceps muscle and participates in the anastomotic network around the elbow.
Superior Ulnar Collateral A branch of the brachial artery that contributes to the periarticular arterial network. This vessel forms important anastomoses with the posterior ulnar recurrent artery.

Brachial The main arterial trunk of the upper arm that continues the axillary artery. The brachial artery provides the primary blood supply to the upper limb and gives off numerous branches.
Inferior Ulnar Collateral A significant anastomotic vessel arising from the brachial artery. This artery forms connections with both anterior and posterior ulnar recurrent arteries.
Anterior Branch of Profunda A major division of the profunda brachii artery supplying the anterior compartment. This vessel participates in the anastomotic network around the lateral epicondyle.
Radial Collateral Branch of Profunda A terminal branch that forms important anastomoses on the lateral aspect of the elbow. This vessel connects with the radial recurrent artery.

Radial Recurrent An ascending branch from the radial artery that participates in lateral elbow anastomoses. This vessel is crucial for maintaining blood flow during elbow flexion.
Anterior Ulnar Recurrent An ascending branch from the ulnar artery forming anterior anastomoses. This vessel provides blood supply to anterior elbow structures.
Posterior Ulnar Recurrent A significant anastomotic vessel on the posterior aspect of the elbow. This artery forms connections with the superior ulnar collateral artery.
Interosseous Recurrent A branch from the posterior interosseous artery participating in the posterior elbow network. This vessel contributes to the periarticular anastomoses.
Dorsal Interosseous A major branch running in the posterior compartment of the forearm. This artery supplies deep forearm muscles and participates in wrist anastomoses.
Volar Interosseous The anterior counterpart running in the anterior compartment of the forearm. This vessel supplies anterior forearm structures and contributes to wrist circulation.
Clinical Significance and Applications
The arterial anastomoses around the elbow joint represent a crucial vascular network that ensures tissue perfusion during various joint positions and movements. This complex system provides multiple collateral pathways that become especially important during vascular compromise or surgical procedures.
Surgical Considerations
Surgical approaches to the elbow must consider these vascular patterns to prevent iatrogenic injury. Understanding the anastomotic network guides surgical planning and helps preserve critical blood supply.
Vascular Assessment Guidelines
Clinical evaluation of elbow circulation requires knowledge of normal vascular patterns. Various diagnostic tests help assess the adequacy of collateral circulation.
Emergency Management
Trauma to the elbow region necessitates careful vascular assessment. Understanding the anastomotic network helps in predicting potential areas of compromise.
Pathological Implications
Various conditions can affect elbow vasculature, including:
- Arterial thrombosis
- Compartment syndrome
- Vascular malformations
- Traumatic injuries
