Q
  1. What is the action of the biceps?
  2. What deformity is associated with this?
  3. What test helps dx this?
  4. What kind of injury is this?
  5. Indications for surgery? 3
  6. At what point is the tendon strong enough to lift one lb?
  7. Which part of the picture is the tendon and which is edema?
A
  1. Bicep supinates more than flexes.
  2. Popeye’s deformity
  3. Hook test- lateral to medial through the anticubital fossa. theres only one this thats there
  4. This is an enthesopathy
  5. Indications for surgery to fix distal biceps tear:
    - laborer- screwdrivers, door handles,
    - Pain/cramps - popeye deformity
    - Cosmetic- girls or skinny guys
  6. Steriods will weaken these. at the three months the tendon is strong enough to lift a 1lb
  7. 2- white is water, edema. balled up stuff is biceps tendon

Q

Tennis/Golf Elbow

  1. Histology?
  2. What kind of collagen is this?
  3. What parts of the elbow do each present on?
  4. How should we examine it? 3
  5. Imaging?
  6. Tx? 3
  7. If not getting better when do something else?
A
  1. Angiofibromistic metaplasia: METAPLASTIC!
  2. Type 1 collagen- looks like a rope under the microscope
  3. Tennis is on the outside and golf on the inside

4.

  • Feel it/reciprocate the pain
  • Tennis -resisted wrist extension
  • push down on the long finger
    5. don’t really need much imaging but possibly routine plain films
    6. TX:
  • FIRST LINE tx- time and physical therapy 95%
  • NSAIDs- metaplastic tissue does get inflamed
  • Cortisone injections- fenestrate it- stimulate the body’s natural response- 3 shots
    7. If its not getting better after 6-9 months do something else

Surgery- 80%

Q

Where do we always need to palpate for ulnar palsies?

What tests? 3

A
  1. ALWAYS NUMB HERE- push here.

    6. Tx: If you can get it flat on a table then dont need to refer

If not send to Ortho

  • needle (cut cord)
  • Traditional open palmar fasectomy*****
  • collagenous- Zyflex- clostridium toxin into hand
    7. Nodules and plaques in the hand
19
Q
  1. What is a ganglion?
  2. Filled with?
  3. Describe how it keeps accumulating fluid?
  4. DDx for bumps in the hand? 4

  6. Who are more prone to get these?
A
  1. A ganglion rises out of a joint, like a balloon on a stalk. It grows out of the tissues surrounding a joint, such as ligaments, tendon sheaths, and joint linings. Inside the balloon is a thick, slippery fluid, similar to the fluid that lubricates your joints.
  2. Filled with synovial fluid- starts to push out
  3. Creates a one way valve and comes out like a water tower
  4. Bumps in the hand:
    - Ganglion
    - Lipoma
    - Schwannoma (can play like a guitar strip, not up and down but back and forth)
    - AV malformation
  5. you can transilluminate, compressible
  6. People with arthritis are more prone to get ganglions
20
Q

What is this?

A

Arthritis

21
Q
  1. Arthritis is what?
  2. What is the extremely aggressive form of OA?
A
  1. inflammation of the joint because of loss of cartilage- osteoarthritis

cortisol

  1. obliterans- crazy aggressive form of OA
22
Q

Describe Swan Neck and Boutonnieres

These occur with what?

Tx?

A

These are with tendon ruptures and lacerations

Swan neck injury is at the DIP joint

Boutonniere injury is at the PIP joint

Refer to ortho

23
Q

What do lumbercles do?

A

Lumbericle- flexes at your MP joints, and extends your IP joints

24
Q
  1. What are the two flexors in the hand?
  2. Which goes distal?
  3. Which goes to the middle phalanx?
  4. What is camper’s chiasm?
A
  1. FDP and FDS are the two flexor tendons in the hand
  2. deep goes distal- deep has a common muscle body-
  3. FDS goes to the middle phalanx
  4. crossing of the tendons, the passage of the tendons of the flexor digitorum profundus through the interval left by the decussation of the fibers of the tendons of the flexor digitorum superficialis
25
Q

What is this?

A

Mallet/ Jersy

26
Q

Mallet

  1. Cause?

Jersey

  1. Cause?
A
  1. tear of the tendon off the DIP
  2. FDP off the middle finger = jersey finger
27
Q
  1. What is a felon?
  2. Tx? 2
  3. DDx that you should watch for?

28
Q

OT TALK

What is the MOI for Mallet Finger?

Mechanism of injury is a hard hit to the distal end of the finger

29
Q

OT TALK

Conservative Treatment of Mallet Finger

A
  1. Splint the DIP joint in extension or slight hyperextension for 6-8 weeks
  2. If they bend the DIP joint it starts the 6 weeks over
  3. When the splint is discharged begin AROM at the DIP joint
  4. Wear splint another 2 weeks at night
30
Q

Boutonniere Deformity

  1. Most common MOI?
  2. Can also be caused by? 2
A
  1. Mechanism of injury is usually caused by a forceful blow to the bent finger

2.

  • It can also be caused by a cut to the top of the finger, which can sever the central slip from its attachment from the bone
  • It can also be caused by rheumatoid arthritis
31
Q

Conservative Treatment of Boutonniere Deformity

4

A
  1. Splint the PIP joint in extension for 6-8 weeks leaving the DIP joint free

33
Q

What is a stener lesion?

A

It occurs when the aponeurosis of the adductor pollicis muscle becomes interposed between the ruptured ulnar collateral ligament (UCL) of the thumb and its site of insertion at the base of the proximal phalanx. Cannot heal spontaneously

If they have that little chip of bone may want to get a hand surgeon to look at it

3

A
  1. Hand based thumb spica splint for 6 weeks

  3. At 6 weeks begin ROM
35
Q

36
Q

Conservative Treatment of Carpal Tunnel Syndrome

4

A
  1. Night splinting. May splint in the day if symptoms are severe
  2. NSAIDs
  3. Stretching and nerve guides
  4. Ergonomic instruction/Behavior modification
37
Q

Cubital Tunnel Syndrome

  1. Caused by?
  2. Symptoms are?
A
  1. Cubital tunnel is caused by compression of the ulnar nerve in the cubital tunnel
  2. Symptoms are numbness in the ulnar side of the ring and small finger
38
Q

Conservative Treatment of Cubital Tunnel Syndrome

A
  1. Night splinting the elbow in extension.
  2. NSAIDs

  1. AKA?
  2. Symptoms are?
  3. Pain with?
A
  1. Also called tennis elbow
  2. Symptoms are pain at the lateral elbow.
  3. Pain with resisted wrist extension and supination.
40
Q

Conservative Treatment of Lateral Epicondylitis

4
