The long head of the biceps originates from the glenoid tubercle and superior labrum.
Rupture of the proximal biceps tendon comprises 90-97% of all biceps ruptures
Often in men aged 40-60y
- Almost exclusively involves the long head.
- Aka "Popeye Arm" (distal contraction of the muscle belly)
- May be acutely traumatic or microtears & age associated degeneration
- Minimal loss of function because short head of biceps remains attached
- Many patients can be treated non operatively
- Most asymptomatic after 4-6 weeks
- Place in sling, ice, analgesia
- Refer to ortho for re-evaluation and determination of operative versus conservative management
