bicipital aponeurosis

bi·cip·i·tal ap·o·neu·ro·sis

, aponeurosis bicipitalis [TA]
radiating fibers from the distal tendon of attachment (insertion) of the biceps that form a triangular band passing obliquely across the hollow of the elbow to the ulnar side and becoming merged into the deep fascia of the forearm, thus providing the muscle with an indirect attachment to the subcutaneous border of the ulna. Formerly called "grace Dieu" fascia, it serves to protect the brachial artery and median nerve during phlebotomy of median cubital vein.

bicipital aponeurosis

a flat sheet of connective tissue that fans out from the medial side of the tendon to blend with deep fascia covering the anterior compartment of the forearm.

bicipital aponeurosis

A radiating triangular band of fibrotendinous tissue that obliquely traverses the ulnar hollow of the elbow and merges with the forearm’s deep fascia. The bicipital aponeurosis provides a tissue plane that protects the brachial artery and median nerve in phlebotomy of local veins.

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.
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 [1].
