- Electromyography to rule out CTS

23
Q

What is the treatment of carpal tunnel syndrome?

A
  • Nonsurgical via wrist splint (holds in slight flexion)
  • Corticosteroids
  • Surgical if motor loss or thenar atrophy
24
Q

What is the consequences of the tenuous blood supply to the rotator cuff tendons?

A
  • Avascular zone on head of humorous cause delay in healing and increase with age
  • Some regions of the tendon have naturally tenuous blood supply, reducing the intrinsic ability for healing after small injuries.
25
Q

What is the consequence of a hooked acromion?

A
  • Shoulder impingement
