LHB in medical terms refers to the Long Head of the Biceps Brachii tendon.
The long head of the biceps brachii tendon is a common source of shoulder pain. It's one of two tendons attached to the biceps brachii muscle (the other being the short head) which helps flex and supinate the forearm.
Here's a more detailed breakdown:
-
Biceps Brachii Muscle: This muscle, located in the upper arm, has two tendons at the shoulder: the long head and the short head.
-
Long Head of the Biceps (LHB): This tendon originates within the shoulder joint, attaching to the supraglenoid tubercle of the scapula. Because of its location and biomechanics, it's vulnerable to injury.
-
Function: The biceps brachii muscle, and therefore its long head tendon, assists in flexing the elbow and rotating the forearm (supination). The LHB also contributes to shoulder stability.
-
Common Problems: Common issues involving the LHB include:
- Tendinitis/Tendinopathy: Inflammation or degeneration of the tendon.
- Tears: Partial or complete ruptures of the tendon.
- Subluxation/Dislocation: The tendon slips out of its normal groove.
-
Diagnosis: Diagnosis usually involves a physical exam and imaging studies like MRI.
-
Treatment: Treatment options range from conservative measures like rest, physical therapy, and injections to surgical intervention in severe cases.
In summary, LHB represents the Long Head of the Biceps Brachii tendon, a structure in the shoulder frequently involved in pain and injury.
