Abstract

Background: In this report we present a series of cases representing variant origin and course of the ulnar artery, namely the superficial ulnar artery, observed during the review of collection of historical specimens prepared in the 19th century by the prominent Polish anatomist Ludwik Karol Teichmann and his collaborators, exhibited in the Anatomy Museum of Jagiellonian University Medical College.

Results: Three distinct variants of the superficial ulnar artery were found on anatomical specimens of the upper limb with arteries injected by using Teichmann’s method. In case No. 1, the superficial ulnar artery originated from the brachial artery slightly above the interepicondylar line of the humerus. This aberrant vessel gave off the common interosseous artery in the upper half of the cubital fossa and then ran superficially to the bicipital aponeurosis and over the muscles arising from the medial epicondyle of the humerus. The cases No. 2 and 3 involved two similar variants of the superficial artery in which the common interosseous artery arose from the radial artery. In the unique case No. 4, the superficial ulnar artery arose from the radial artery.

Conclusions: The superficial ulnar artery shows diverse anatomy regarding its topography and  blood supply territory. Orthopedic, hand, and plastic surgeons should be aware of anatomic variations of the SUA both in planning and in conducting surgeries of the upper limb.
