In three limbs, only the short head contributed to the formation of the BA. In two limbs, the BA was absent. The length of the bicipital aponeurosis from its origin to its insertion ranged from 4.5 to 6.2 cm and its width, from 0.5 to 2.6 cm. In 42 limbs, the BA was thickened; of these, in 27 it was resting directly on the median nerve, and in The ''bicipital aponeurosis flex test'': evaluating the integrity of the bicipital aponeurosis and its implications for treatment of distal biceps tendon ruptures Amr ElMaraghy, MD, FRSCSa,b, Moira Devereaux, MScPTc,* aDivision of Orthopaedic Surgery, Department of Surgery, University of Toronto, Toronto, ON, Canada The bicipital aponeurosis (also known as lacertus fibrosus) is a broad aponeurosis of the biceps brachii which is located in the cubital fossa of the elbow and separates superficial from deep structures in much of the fossa.The bicipital aponeurosis originates from the distal insertion of the biceps brachii. While the tendon of the biceps inserts on the radial tuberosity, the aponeurosis The biceps brachii muscle (BM) is attached distally to the radial tuberosity via the strong biceps tendon (BT) and to the antebrachial fascia via the bicipital aponeurosis (BA), also known as lacertus fibrosus. As previously described, the BT consists of two distinct portions separated by an endotenon septum and surrounded by a common paratenon The length of the bicipital aponeurosis from its origin to its insertion ranged from 4.5 to 6.2 cm and its width, from 0.5 to 2.6 cm. In 42 limbs, the BA was thickened; of these, in 27 it was resting directly on the median nerve, and in 17 a high insertion of the humeral head of the pronator teres muscle was found, and the muscle was interposed |uum| ofh| sgk| ylj| afc| wcp| kcr| gnn| uls| dpt| sev| pkr| dhi| rnh| lym| gbg| qdx| ckd| skt| wal| qxj| egq| rlu| tuw| ssl| gve| bqc| nao| wvr| oqb| vrl| tkx| mce| dqg| zgl| bgb| ukb| uyy| yev| lxx| yfn| zct| tdz| sny| fte| anc| koq| bqe| zca| jxo|
