10
Q
what is a ulnar collateral ligament injury?
A
- this is a injury that results from a valgus force due to repetitive trauma.
11

- pain w/ valgus stress test @ 20 degrees
13
Q
management for a UCL sprain?
A
- conservative treatment w/ RICE & NSAIDS.
- can resolve with strengthen ing of flexors and pronators.

14
Q
what is a MOI for elbow dislocation?
A

severe torsion or varus or valgus force at the elbow when it is in a fixed position
15
Q
name 3 ways a elbow dislocation bone can be displaced?
A
- anterior
- posterior
- laterally
16
Q
what is a elbow dislocation?
A
- this is where the ulna will come out of the humeral ulnar joint after or posteriorly or laterally.
17
Q
s/s of elbow dislocations?
A
- swelling
- severe pain
- check that radial pulse is still present.
18
Q
what are complication / things that could develop due to a elbow dislocation?
A
- myositis ossificans and calcification of tissue around the jt.
- decreased ROM from scar tissue
- ulnar nerve entrapment by scar tissue.
- damaged arteries and nerves
- possible # of radial head.
19
Q
what is elbow osteochondritis dissecans?
A
- degeneration of the articular cartilage in the elbow. the cartilage has been torn apart.
- this is seen in young throwing athletes.
20
Q
what is a MOI for elbow OCD?
A
- repetitive micro trauma w/ movements of rotation, extension, valgus stress causing compression of the radial head and shearing of the radiocapitular jt.
21
Q
s/s of OCD of the elbow?
A
- sudden pain
- locking
- swelling
- crepitus
- decreased ROM
22
Q
management of OCD elbow?
A
- activity restriction for 6-12 wks.
- NSAIDS
- splint or cast in severe cases
- possible surgery.
23
Q
3 fractures of the elbow/ forearm?
A
- distal humerus
- proximal radius
- proximal ulna
24
Q
what is volkmann’s ischemic contracture?
A
- disruption to the blood vessels and nerves. this is also a complication of a elbow fracture.
25
what deformity would you notice of someone with volkmann's ischemic contracture?
- wrist and the proximal finger joints are in extension.
- distal finger joints in flexion.
26
s/s of someone with volkmann's ischemic contracture?
- pain in forearm increased w/ passive extension of the fingers.
- pain is followed by cessation of brachial and radial pulses.
27
3 forces placed on the forearm from throwing sports?
- medial tension
- lateral compression
- posterior compression
28
overuse in throwing during adolescence growth period is. known as what?
little league elbow
29
what is cubital tunnel syndrome?
- ulnar nerve dislocation or subluxation.
- this is also due to lax impingement or progressive compression of ligament on the nerve.
- repetitive movement to the ulnar nerve
30
s/s of cubital tunnel syndrome?
- pain medial which may be referred proximally or distally
- tenderness in cubital tunnel on palpation and hyper flexion
- intermittent paresthesia in 4 and 5th finger.
31
management of cubital tunnel syndrome?
- rest immobilization for 2 weeks w/ NSAIDS
- avoid values and hyper flexion stresses.
- possible surgery with subluxation of nerve
32
what is pronator teres syndrome?
- entrapment of the medial nerve. this nerve may become entrapped due to oedema or muscle hypertrophy.
33
s/s of pronator teres syndrome?
- sensory deficits, numbness, tingling, pins & needles in digits 1-4 (half of the fourth digit.)
- motor deficits, loss of flexion and weakness.
34
management of pronator teres syndrome?
- rest NSAIDS
- modified activity.
