26
Q

Identify

A

Long head biceps tendon rupture

27
Q

What are the key considerations when weighing treatment options for musculotendinous ruptures?

A
  • Impact of missing muscle
  • Presence of alternative muscles
  • Functional requirements of the patient

Disorder of the bony attachment of a muscle or tendon

29
Q

Define: tendinitis

A

Acute inflammation of a tendon

traumatic: pull or blow
