Shoulder Flashcards
shoulder
CROSS BODY ADDUCTION TEST:

- +ve test is pain reproduction
shoulder
Which is the most common type of shoulder dislocation?
80-90% are anterior
shoulder
Types of RCT surgeries:

AB/ER
shoulder
Why a Humeral Shaft Fx may damage the radial nerve? How would asses a radial nerve injury?
- radial nerve raps around the the mid shaft of the humerus

shoulder
when does resistive test: MMT / MSTT, occur during the exam?
after PROM
before muscle lenght (if needed)
shoulder

labral tear
shoulder
Difficulty moving the arm not due to pain:
- nerve issue
- frozen shoulder (adhesive capsulitis)
shoulder
The higher the positive LR…
the better it is
shoulder

- CAL
shoulder
What type of joint is the AC joint?
plane joint
shoulder
Adhesive capsulitis tx:
- Modalities
- Mobilization
- Stretching
- Corticosteroid injection (after one month of PT)
- Manipulation under anesthesia (if no progress in 6 months)
shoulder
Type I slap associated with:
RCT
shoulder
Arm feels loose or slips “in or out”
possible dislocation, instability
shoulder
Moderate irritability pain scale:
4-6/10
shoulder
which RC muscles are prone to lenghten?
supraspinatus and infraspinatus
shoulder
What happens in a GRADE II AC sprain?
Surgery? Sling for how long?
Back to normal in how long?
- Complete Tear of the AC ligament and a sprain (stretching) of the CCL
- No surgery. Sling 2-4 weeks
- Rehab a minimun of 3 months
shoulder
Stages of adhesive capsulitis:
- Pre-adhesive stage: Mild synovitis patients present with mild end-range pain
- Freezing stage: Thickened synovitis acute discomfort and very painful end range movement
-
Frozen stage: Less synovitis and mature adhesions significant
stiffness with less pain (established contractures) - Thawing phase: Capsular restrictions without synovitis painless stiffness motion slowly improves
shoulder
Treatment of a prox humerus fx that opend reduced
- Some evidence that ‘immediate’ PT compared to 3 weeks immobilization (then PT) had reduced pain and better function for non-displaced fractures
shoulder
Which ligament s give the greatest passive stability to the shoulder at rest?
- SGHL
- CHL
shoulder
How is atraumatic multidirectional bilateral instability of the shoulder treated?
- Rahabilitation initially (3months)
- Inferior capsular shift repair (incision of the capsule)
shoulder
Adhesive capsulitis:
Limitations
Demographics
Other facts?
- Limitation in ext rotation the most
- Insidious onset
- Usually between 40-65 years old with an incidence greater in females
- There is between 5-35% chance it happens on the other side
- Increases to 10-40% in patients with diabetes or thyroid dysfunction
shoulder
What is the position of the pt for palpattion of infasp/teresminor?
prone on elbows, shifting their weight to the side being palpated
shoulder
most common fxs?
humerus and clavicle
shoulder
What is the goal of adhesive capsulitis PT tx?
-
GOAL: treat based on irritability
- LESS is MORE
shoulder
True or false:
Adhesive capsulitis increases to 10-40% in patients with diabetes or thyroid dysfunction

Pancoast’s Tumor, referred pain
A Pancoast tumor, also called a pulmonary sulcus tumor or superior sulcus tumor, is a tumor of the pulmonary apex. It is a type of lung cancer defined primarily by its location situated at the top end of either the right or left lung. It typically spreads to nearby tissues such as the ribs and vertebrae. Most Pancoast tumors are non-small cell cancers.
