Inferior ulnar collateral artery the anterior ulnar recurrent. Behind the medial epicondyle a branch anastomoses with the superior ulnar collateral and posterior ulnar recurrent arteries. Inferior ulnar collateral artery The inferior ulnar collateral artery (anastomotica magna artery) is a artery in the arm. It arises about 5 cm. above the elbow from the brachial artery. It passes medialward upon the Brachialis, and piercing the medial intermuscular septum, winds around the back of the humerus between the Triceps brachii and the bone, forming, by its junction with the profunda brachii, an arch above the olecranon fossa. As the vessel lies on the brachialis, it gives
Brachial plexus block subjected himself to the supraclavicular block. Later that year, Georg Hirschel (18751963) described a percutaneous approach to the brachial plexus from the axilla. In 1928, Kulenkampff and Persky published their experiences with a thousand blocks without apparent major complications. They described their technique with the patient in the sitting position or in the supine position with a pillow between the shoulders. The needle was inserted above the midpoint of the clavicle where the pulse of the subclavian artery could be felt and it was directed medially toward the second or third thoracic spinous process. By the late 1940s, clinical experience
