To test for compression from the bicipital aponeurosis
, ask the patient to flex the elbow to approximately 120[degrees] to 130[degrees] and apply active supinated resistance.
38-40) Of note, the tendon rarely retracts significantly into the arm because it is partially tethered by the bicipital aponeurosis
, also known as the lacertus fibrosis.
It is passing superficial to the bicipital aponeurosis
in the cubital fossa and subjacent to the median cubital vein.
6) The distal tendon spirals in a predictable pattern distally to the bicipital aponeurosis
, spiraling clockwise in left elbows and counterclockwise in right elbows.
Along the course, it ran superficial to the bicipital aponeurosis
& muscle of front of forearm.
12) and then crossed the median nerve under cover of bicipital aponeurosis
The common observation noted with the variation of the artery from the arm was the course from the upper third of the brachial artery, superficial to median nerve and behind bicipital aponeurosis
at the elbow.
Along its course, part of this nerve enters the axilla of the shoulder, runs immediately adjacent to the biceps, and descends within the hollow of the elbow under the pronator teres muscle and the bicipital aponeurosis
28,29) The tendon does not retract if the bicipital aponeurosis
(lacertus fibrosis) remains intact.
1998); anatomical variations and vascular chains surrounding the nerve, as related by Braun & Spinner, 1991, they noticed during a surgical intervention, that the compression of the nerve occurred in the distal part of the arm, caused by communicating veins that jointed to the cephalic and basilic veins and with the brachial vein through a bicipital aponeurosis
In the antecubital fossa the median nerve and brachial artery are located in a closed compartment underneath the bicipital aponeurosis
In 10% of cases a third head arises from the superomedial part of brachialis and is attached to the bicipital aponeurosis
, which descends medial side of the tendon of insertion .
