BACKGROUND The accuracy of the physical examination for tears of the long head of the biceps remains controversial. PURPOSE The goals were 1) to characterize the occurrence of partial tears of the long head of the biceps tendon in a group of consecutive patients, and 2) to analyze the diagnostic value of various clinical tests for pathologic lesions of the proximal biceps tendon. STUDY DESI...

Unilateral three headed biceps brachii muscle was observed in the dissected cadaver of a 45-year-old Nepalese cadaver. The supernumerary head is taking origin from the tendon of deltoid and crossing in front of the long head of biceps and joining with short head of biceps brachii. The incidence of this variation is very rare and there was no available literature in Nepalese population. Presence...

We dissected 30 cadaveric knees to provide a detailed anatomic description of the biceps femoris muscle complex at the knee. The main components of the long head of the muscle are a reflected arm, a direct arm, an anterior arm, and a lateral and an anterior aponeurosis. The main components of the short head of the biceps femoris muscle are a proximal attachment to the long head's tendon, a caps...

The hamstring muscle group consists of three muscles in the posterior thigh; the semitendinosus (ST) and the semimembranosus (SM) are located at the medial side, the biceps femoris at the lateral side (BF) [1]. The biceps femoris has two heads, which are anatomically and functionally distinct; the short (BFsh) and the long (BFlh) head. The semitendinosus and long head of the biceps femoris have...

Ten cadaveric shoulders were tested to evaluate the effect of simulated contraction of the long head of the biceps brachii on glenohumeral translation. The shoulders were mounted on a special apparatus attached to a servo-controlled hydraulic testing device. Sequential 50 N anterior, posterior, superior, and inferior forces and a 22 N joint compressive load were applied to the shoulders. An air...

INTRODUCTION It is well known that the biceps functions mainly as an elbow flexor and forearm supinator. In vivo elbow flexion and forearm supination strength testing after rupture of the long head of the biceps tendon has shown decreases of 0-16% and 0-21%, respectively [1,2]. Although many studies have attempted to identify the role of the long head of the biceps brachii muscle in elbow flexi...

INTRODUCTION: Pathologic changes in the long head of the biceps tendon are common clinically in conjunction with rotator cuff tears [1,2]. However, there is some debate regarding the role of the biceps at the shoulder following a cuff tear [3,4] and therefore, controversy exists regarding its treatment. A previous study in a rat model determined that the biceps tendon was detrimentally affected...
