Q

What movements/contractions are most provocative with Flexor tendinopathy ?

A
  1. Flexion contractions

2. Movements tested in extension and pronation

17
Q

What nerves may also be involved in Flexor tendinopathy ? (2)

A
  1. Ulnar nerve

2. median nerve

18
Q

Which is more common, a chronic or acute MCL injury ?

19
Q

Common cause of chronic MCL injury

A

throwing –> excessive valgus force –> potential acquired laxity

20
Q

What muscles should be targeted for MCL injuries

A

Pronator and forearm

21
Q

What is Cubital Tunnel Syndrome

A

Ulnar Nerve compression

22
Q

What can cause cubital tunnel syndrome (6)

A
  1. Traction injuries
  2. Recurrent nerve subluxation
  3. Anatomical changes
  4. Direct blow
  5. Mechanically leaning on elbow
  6. Hypertrophy of FCU
23
Q

What movement is most provocative for cubital tunnel syndrome

A

sustained flexion

24
Q

What is the treatment principle for cubital tunnel syndrome

A

Treat the underlying cause - valgus instability, leaning too much etc.

25
Most common causes of posterior elbow pain (3)
1. Olecranon Bursitis 2. Triceps Tendinopathy - less common 3. Posterolateral impingement
26
Special consideration when olecranon bursitis is present
look for systemic signs of inflammation
27
What causes posterolateral impingement (2)
1. Bony changes (usually OA) around the olecranon | 2. Acute event - forced into extension
28
What movement is most painful for Posterolateral impingement ?
terminal elbow extension
29
What mobs are useful for Posterolateral impingement
Mobs of the ulnohumeral joint

31
Common point of entrapment for the Median nerve
Carpal tunnel Pronator Heads
32
Common point of entrapment for the Radial nerve
Arcade of Frohse Between supinator
