Elbow Sprains Flashcards
How are most valgus stress overloads caused? (what is the mechanism)
- Trauma (FOOSH)
- Overuse or repetitive stress with overhead sports
What structure is most commonly involved in a valgus stress overload (sprain)?
The 3 portions of the UCL
Where is the anterior UCL located and what is its primary job?
- Primary stabilizer
- Runs from the medial epicondyle to the coronoid
- Runs anterior to the ulnar nerve
Where is the posterior UCL located?
Runs medial to the epicondyle to the olecranon
Where is the transverse UCL located?
Runs from the olecranon to the coronoid
The UCL provides a _____ stability and prevents _____ stress.
Provides a medial stability and prevents a valgus stress
With a valgus stress overload what will your ROM scan look like?
Likely more pain and limitation into extension (possibly some pain and limitation into shoulder ER as well)
With a valgus stress overload what will your stress tests scan look like?
- Pain with distraction
- Relief with compression
With a valgus stress overload what will your stability test scan look like?
(+) stability tests
- Valgus stress test at 0 and 90 degrees
- UCL instability (high sensitivity)
What two conditions do you have two rule out when you have a valgus stress overload to determine you truly have this condition? (differential diagnosis)
- Medial epicondyle apophysitis
- Tendinopathy
What is the cause of a varus stress overload? (mechanism)
Same as UCL but with a varus stress:
- Trauma (FOOSH)
- Overuse or repetitive stress with overhead sports
What structure is involved with a varus stress overload (sprain)?
RCL
Where does the RCL run from?
It is triangular shaped so it comes from the lateral epicondyle to the annular ligaments to the lateral radius
The RCL provides a _____ stability and prevents a _____ stress.
Provides a lateral stability and prevents a varus stress
With a varus stress overload what will your ROM scan look like?
Likely more pain and limitation with flexion
