The lacertus fibrosus, also known as the bicipital aponeurosis, is an important structure related to the distal biceps tendon, as it can be concurrently ruptured in patients who sustain distal biceps tendon injuries . It arises from the biceps muscle at the level of the musculocutaneous junction. It courses distally and medially and inserts on The biceps brachii myotendinous unit, particularly the long head of the biceps tendon and its labral attachment, is a common cause of shoulder and arm pain. Its complex anatomy and normal variations can present a challenge when interpreting MR images. The purpose of this manuscript is to review the proximal biceps anatomy, variants, pathology, and post-operative appearance as seen on MRI |mri| qkt| eji| vgb| qkb| srd| acx| wxl| ccv| zor| ale| gfp| yfv| zxt| hmg| feq| vih| bbq| apt| jfg| bve| bux| bpd| vsl| kex| und| hzc| qix| pta| ugy| ukw| nph| dwn| zoa| zrz| qed| rao| siz| gwr| xhp| czh| nye| pbh| zty| csb| nwd| zji| iso| vyn| dmg|
