partial median nerve entrapment in the distal arm because of an accessory Bicipital Aponeurosis
Journal of Hand Surgery (European Volume), 1991Co-Authors: Robert J Spinner, Stephen W Carmichael, M SpinnerAbstract:We present a newly described entrapment of the median nerve caused by compression in the distal arm because of an accessory Bicipital Aponeurosis. It is characterized by the paresis or paralysis of muscles innervated by the anterior interosseous branch of the median nerve-the flexor pollicis longus, the flexor digitorum profundus, and the pronator quadratus-as well as other more proximal median nerve innervated muscles, namely, the pronator teres and flexor carpi radialis. Sensibility is intact. The site of the Tinel's sign in the distal arm and the clinical appearance of an accessory Bicipital Aponeurosis help to localize the lesion. Electrodiagnostic studies are also important in establishing the site of the entrapment. The clinical and surgical findings are correlated with the internal topography of the median nerve at its site of compression. It is important to differentiate this syndrome from the classic anterior interosseous syndrome and other nerve entrapments at the elbow and arm. Surgical exploration is indicated if there is no clinical or electromyographic improvement in three to four months after the onset of symptoms.

High origin of an ulnar artery--development and surgical significance.
Chang Gung medical journal, 2011Co-Authors: Venkata Ramana Vollala, Raghu Jetti, Simmi SoniAbstract:Variations in the main arteries of the upper limb are common and these anomalies can be of substantial interest to orthopedic surgeons, plastic surgeons, radiologists and anatomists. We present here a case of a high origin of the ulnar artery from the brachial artery found during anatomical dissection of a right upper limb of a 50-year-old man. This superficial ulnar artery, after running over the Bicipital Aponeurosis in the cubital fossa superficial to the flexor muscles in the forearm terminated as the superficial palmar arch in the hand. The embryological and clinical importance of the anomalous ulnar artery is discussed. (Chang Gung Med J 2011;34(6 Suppl):39-42)

The superficial ulnar artery: development and clinical significance
Jornal Vascular Brasileiro, 2007Co-Authors: Srinivasulu Reddy, Venkata Ramana VollalaAbstract:The principal arteries of the upper limb show a wide range of variation that is of considerable interest to orthopedic surgeons, plastic surgeons, radiologists and anatomists. We present here a case of superficial ulnar artery found during the routine dissection of right upper limb of a 50-year-old male cadaver. The superficial ulnar artery originated from the brachial artery, crossed the median nerve anteriorly and ran lateral to this nerve and the brachial artery. The superficial ulnar artery in the arm gave rise to a narrow muscular branch to the biceps brachii. At the elbow level the artery ran superficial to the Bicipital Aponeurosis where it was crossed by the median cubital vein. It then ran downward and medially superficial to the forearm flexor muscles, and then downward to enter the hand. At the palm, it formed the superficial and deep palmar arches together with the branches of the radial artery. The presence of a superficial ulnar artery is clinically important when raising forearm flaps in reconstructive surgery. The embryology and clinical significance of the variation are discussed.

A artéria ulnar superficial no braço deu origem a um ramo muscular estreito do músculo bíceps braquial. Ao nível do cotovelo, a artéria percorria superficialmente a aponeurose Bicipital, onde era cruzada pela veia cubital mediana. Percorria, então, em sentido descendente e medialmente superficial aos músculos flexores do antebraço, e então descendia para entrar na mão. Na palma, essa artéria formava os arcos palmares superficial e profundo junto com os ramos da artéria radial.Apresença de uma artéria ulnar superficial é clinicamente importante ao levantar retalhos do antebraço em cirurgias reconstrutivas.Aembriologia e relevância clínica da variação são discutidas
