Flashcards in 02 Elbow Deck (40):
landmark for lymph nodes
medial and lateral supracondylar ridge
Where is the sublime tubercle and what does it do?
- where the UCL attaches at distal end
- creates isometricity
________ can form on olecranon process or foss, causing posterior pain
Most common site on the elbow for itis/osis
What is 1 body inch distal to the lateral epicondyle?
What is significant about the radiocapitellar joint?
radial head is a common site for OA changes or OCDs
What is OCD?
The UCL is _____ to the sublime tubercle
UCL is susceptible to _____
How is the annular ligament commonly injured?
- in children
- radial head subluxation - distraction force
Function of the annular ligament
stabilize radial head
characteristic of olecranon bursitis
it's as big as a grapefruit
What is the significance of the palmaris longus?
- absent in 15% of the population
- commonly harvested for UCL reconstruction
What is the combo of brachioradialis, ECRL, and ECRB called?
mobile wad of 3
- extensor digitorum
What's in the antecubital fossa?
- lacertus fibrosus
- brachial artery
- median nerve
What muscles outline the antecubital fossa?
- pronator teres
true axis measurement
- line up gonio with 3rd metacarpal (true axis) and line up moveable arm with 2nd metacarpal
move gonio to the side of the hand to measure (Davies says it's more accurate)
What is usually the hardest movement to regain after injury?
What is the carrying angle?
valgus angle at the elbow
How do you note negative values?
for less ROM: 0˚-5˚-150˚
MMT for flexion
positions and muscles
- supinated: biceps
- neutral: brachioradialis
- pronated: brachialis
What are the MMT for the elbow?
- flexion (biceps, brachioradialis, brachialis)
- extension (triceps)
2 techniques for MMT pronation/supination
- handshake technique
- grasp forearm
Why would you choose to not use the handshake technique for MMT?
a patient with intrinsic hand problems
close packed position of the elbow
Why do you go to 30˚ flexion for the elbow stability tests, what are you doing?
isolating the posterior band of the capsule
Which test was developed by patients?
- milking tests
If a patient can't do the milking test, what do you have to do?
- grab thumb and place valgus force
- can put them at 90˚ abduction
What are the elbow neuro tests?
- Tinel's ulnar nerve test
- elbow flexion test
- pronator teres syndrome test
- pinch grip test (testing ant. interosseous br of median n.)
Tinel's ulnar nerve test signifies inflammation if:
tingling goes distal
pinch grip test results
- normal = tip to tip
- + if using adductor to substitute
What should you see with the valgus stress test at 30˚ as compared to 0˚?
should have more motion
Why are we not doing the valgus stress test at 90˚?
too much shoulder involvement
