Anterior ulnar recurrent artery

Anterior ulnar recurrent artery is a significant artery in the human forearm. It plays a crucial role in supplying blood to the elbow joint and surrounding muscles. This artery originates from the ulnar artery, one of the major arteries in the forearm, immediately distal to the elbow joint.

Anatomy

The anterior ulnar recurrent artery arises near the elbow from the medial aspect of the ulnar artery. After its origin, it ascends anteriorly, moving towards the elbow. In its course, it is located medially, lying in close proximity to the ulnar nerve. The artery then divides into several branches, which anastomose with the inferior ulnar collateral artery and the superior ulnar collateral artery, forming a crucial part of the arterial network around the elbow known as the anastomosis around the elbow joint.

Function

The primary function of the anterior ulnar recurrent artery is to supply blood to the anterior part of the elbow joint and to contribute to the rich collateral circulation around the elbow. This ensures a continuous blood supply during arm movements that may otherwise compress major arteries and restrict blood flow.

Clinical Significance

The anterior ulnar recurrent artery is of particular interest in surgical procedures involving the elbow or forearm, as well as in the diagnosis and treatment of traumatic injuries to the elbow. Its role in maintaining collateral circulation makes it a key vessel in preserving the functionality of the elbow joint after injury or surgery.

Related Conditions

Conditions affecting the anterior ulnar recurrent artery include arterial occlusion, which can lead to compromised blood flow to the elbow joint and surrounding structures. Trauma to the forearm or elbow can also damage this artery, leading to bleeding or the formation of a hematoma.

Treatment and Management

Treatment for issues involving the anterior ulnar recurrent artery typically focuses on restoring proper blood flow and repairing any damage. Surgical intervention may be required in cases of severe trauma or occlusion. In less severe cases, conservative management, including physical therapy and monitoring, may be sufficient.
