pathology
6

A
superior labrum anterior posterior (lesion)
9
Q

0 tears noted in 72% asymptomatic subjects over 40
10
Q

A
- debride or repair (depends on tear type)
- release the LH biceps
11
Q
Slap management depends on age
A

12
Q
SLAP is rarely seen in isolation. What are other conditions that may be concurrent?
A

13
Q
tenodesis
A
Biceps tenodesis is done by detaching your biceps tendon from your labrum and moving the tendon to your upper arm bone (humerus).
14
Q
tenotomy

Biceps tenotomy means cutting off one tendon and not reattaching it, allowing it to heal to the humerus over a few weeks.
15
Q
