LABS: ELBOW Flashcards
differential diagnosis key factors
location**
MOI
Symptomology: during activity –> tendon, after activity –> instability
Age; w/o a growth plate –> NOT PANNERS/growth plate issues
Is the elbow stable? Is it prone to overuse?
Very stable, but less adjustments (gapping one side = compression on other)
PRONE TO OVERUSE, concomitant damage following trauma
Elbow is ___ to figure out whats wrong, ___ to treat
*not a lot of room for error, compensation, we use it all the time
easy to figure out whats wrong, hard to treat
*hard to get the rest you need (cant offload joint without sling, which is not the best for strength overall)
What are Diff DX for elbow pain?
Tendinopathy
Instability
Fracture/dislocation
Neurovascular injury
Bursitis
Non-MSK cause
If elbow is swollen, epicondyles sit ___ compared to olecranon process
in line with
(supposed to be a triangle with epis above)
valgus angulation at elbow
Directs ulna laterally (compared to humerus) during extension motion
carrying angle
normal carrying angle elbow values: males and females
Males: 11-14°
Females: 13-16°
varus deformity may indicate they had a
supracondylar fracture
active elbow flexion norms
140-150
up to __ hyperextension is considered normal
10 degrees
supination norm
pronation norm
85+
75+
valgus stress test is performed in
extension
slight flexion
+ if pain and/or excess mvmt
varus stress test performed in
extension
slight flexion (20-30)
+ if pain and/or excess mvmt
moving valgus stress test is performed in
flexion to extension with valgus stress (around the world)
+ medial elbow pain between 70-120 ROM
2 tests for lateral tendinopathy
- cozen’s (pronation, wrist extension, radial deviation –> resist)
- mill’s (passive pronation, wrist flexion, extension of elbow)
with golfer’s elbow test and mill’s, what should the examiner do?
palpate the epicondyle with one hand while performing the test
how long should you hold the elbow flexion test
3-5 minutes (IDK test for ulnar)
do if tinel’s (4-6 taps at medial elbow) is negative but you are pretty sure its ulnar nerve
Which has better +LR, elbow flexion test or tinel’s?
elbow flexion test
Humero-ulnar joint mobs:
distraction improves what motion
lateral glide?
medial glide?
distraction: all motion
lateral: extension
medial: flexion
Which way should you mob the humero-radial joint to improve extension?
radial head: dorsally
which way should you mob the PRUJ to improve pronation
radial head: dorsally
