Q

Gray hair = ___ ___.

44
Q

Who tends to get rotator cuff tears?

A

Older patients (50s-60s)

45
Q

Most rotator cuff tears are (acute / chronic).

46
Q

People with rotator cuff tears complain of ___ and ___.

A

weakness

pain

47
Q

What may be seen on examination of someone with a rotator cuff tear?

A

Muscle wasting

Weakness (reduced passive movement, normal active movement)

48
Q

What is reduced in the X-ray of someone with a rotator cuff tear?

A

Subacromial space

49
Q

Greater tuberosity

50

51
Q

A

Rest

Analgesia

Sling

PHYSIOOOOO

surgery if required

52
Q

Why are acute rotator cuff tears treated more urgently than chronic ones?
