Week 1: Med-Screening for the Shoulder and Upper Extremity Flashcards
MSK conditions to screen for during an exam for the upper extremity
- Cervical fracture
- Cervical myelopathy
- Upper cervical spine ligament laxity
- Spinal infection
Algorithm for determining if imaging is needed for cervical fracture
- High risk factor? If no, then…
- Low risk factor? If no, then…
- Able to rotate neck 45 degrees? If yes, then no imaging
High risk factors for cervical fracture
- 65+
- Dangerous MOI
- Upper extremity paresthesia
Low risk factors for cervical fracture
- Simple MVC
- Sitting position in ER
- Ambulatory at any time
- Delayed-onset neck pain
- Absence of midline cervical spine tenderness
What is cervical myelopathy
- UMN lesion
- Pressing or pressure against the spinal cord
Mechanical causes of cervical myelopathy
- Trauma (ligament instability, fracture)
- Spinal cord compression
- Degenerative changes
- Bulging discs, thickened ligamentum flavum
- RA w/ atlanto-axial subluxation
Systemic causes of cervical myelopathy
- MS, ALS
- Guillain-Barre
- Multifocal motor myelopathy
Diagnostic cluster for cervical myelopathy
3/5 positive tests:
- Gait deviation
- Hoffman’s test
- Inverted supinator sign
- Babinski test
- > 45 years old
What ligaments are we concerned with for upper cervical ligamentous laxity?
- Alar
- Transverse
Signs and symptoms of upper cervical ligamentous laxity
- Occipital headache and numbness
- Severe limitation during neck AROM in all directions
- Signs of cervical myelopathy
Causes of upper cervical ligamentous laxity
- Trauma
- RA w/ atlanto-axial subluxation, Down syndrome, and Klippel-Fiel
- Os odontoideum
- Odontoid fracture
Os odontoideum
-
Odontoid fracture

How to test for upper cervical ligamenout laxity
- Alar ligament stress test
- Transverse ligament test/anterior shear test
- Sharp-Purser test
Signs and symptoms for spinal infection
- Unrelenting spine pain
- Worse/severe pain at night (no change w/ positions)
- Fever, chills, fatigue
- Concurrent infection or IV drug use
- Possible redness, swelling, warmth
