The biceps brachii primarily serves to supinate the forearm at the elbow joint. [1] The muscle belly is composed of two heads. The short head is more medial and highlighted in green. The long head is more lateral and highlighted in red. A biceps tendon rupture or bicep tear is a complete or partial rupture of a tendon of the biceps brachii muscle.
The most common diagnostic tool is magnetic resonance imaging (MRI), which can sometimes indicate the size of the tear, as well as its location within the tendon. Furthermore, MRI enables the detection or exclusion of complete rotator cuff tears with reasonable accuracy and is also suitable for diagnosing other pathologies of the shoulder joint ...
The rotator interval is a triangular space in the shoulder that is functionally reinforced externally by the coracohumeral ligament and internally by the superior glenohumeral ligament, and traversed by the intra-articular biceps tendon. On imaging, it is defined by the coracoid process at its base, the supraspinatus tendon superiorly and the ...
The bicipitoradial bursa is a bursa located between the distal tendon of the biceps brachii muscle and the anterior part of the tuberosity of the radius. [1] It partially or completely wraps around the biceps tendon. It ensures frictionless motion between the biceps tendon and the proximal radius during pronation and supination of the forearm ...
A SLAP tear or SLAP lesion is an injury to the superior glenoid labrum (fibrocartilaginous rim attached around the margin of the glenoid cavity in the shoulder blade) that initiates in the back of the labrum and stretches toward the front into the attachment point of the long head of the biceps tendon.
The bicipital aponeurosis originates from the distal insertion of the biceps brachii, and inserts into the deep fascia of the forearm. [1] The biceps tendon inserts on the radial tuberosity, and the bicipital aponeurosis lies medially to it. [2] It reinforces the cubital fossa, helping to protect the brachial artery and the median nerve running ...
Dumbbell 21s (bottom, middle, top) Begin standing with your feet hip-width apart. Hold a dumbbell in each hand with arms resting on your thighs and palms facing away from your body.
It identifies the presence of a pathology involving the biceps tendon or glenoid labrum. The specific positive findings to the test include pain in the bicipital groove indicating biceps tendinitis , [ 2 ] [ 3 ] subluxation of the long head of the biceps brachii muscle , [ 3 ] and presence of a SLAP tear .
