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.
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.

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.
6) The distal tendon spirals in a predictable pattern distally to the bicipital aponeurosis
, spiraling clockwise in left elbows and counterclockwise in right elbows.
The common element is moving the proximal trim line entirely into the cubital fold, where it is contoured to accommodate the biceps tendon and bicipital aponeurosis
