The biceps brachii muscle is prone to variants but absence of the long head of the biceps (LHB) tendon is an exceptionally rare anomaly. This report concerns the fourth case of bilateral congenital absence of the LHB tendon and presents the ultrasonography (US) and magnetic resonance (MR) findings. Our case has the peculiarity of being the first in which bilateral LHB tendon agenesis is not ass...

Lesions of the long head biceps tendon (LHB) are frequent causes of shoulder pain and disability. Biceps tenotomy and tenodesis have gained widespread acceptance as effective procedures to manage both isolated LHB pathology and combined lesions of the rotator cuff and biceps-labral complex. The function of the LHB tendon and its role in glenohumeral kinematics presently remain only partially un...

Anatomical variations of the biceps brachii have been described by various authors, but the occurrence of bilateral asymmetric supernumerary heads is rare and has not been reported. We found three accessory heads of the biceps brachii muscle on right arm and an anomalous third head of biceps brachii on left arm. The third, fourth, and fifth heads of right arm originated from the body of humerus...

OBJECTIVE To evaluate the use of magnetic resonance imaging (MRI) without contrast as a diagnostic method of partial lesions of the long head of the biceps, using arthroscopic surgery as the gold standard. METHODS We evaluated data from MRI and arthroscopic surgical findings of patients operated due to rotator cuff and SLAP injuries. MRI without contrast of at least 1.5 T, with a radiologist ...

Introduction Numerous surgical procedures have been developed to address pathology associated with the long head of the biceps tendon. Tenodesis might be preferred over tenotomy for several reasons, including improved cosmetic appearance, maintenance of elbow flexion and supination strength, and maintenance of the biceps muscle length-tension relationship. To our knowledge, there have been no s...
