MK Flashcards
Scapulohumeral Group muscles and job
deltoid, lat dorsi, subscap, supraspinatus, teres minor, infraspinatus
Rotate shoulder and depress/rotate head of humerus
Axioscapular group muscles and job
trap, rhomboids, serratus anterior and levator scapulae
pulls shoulder back and rotate scapula
Axiohumeral group muscles and job
pec major and minor+ lat dorsi
rotate shoulder internally
Where are biceps and triceps most involved?
shoulder ABduction
What lines the shoulder capsule?
synovial membrane w/ 2 outpouchings which are the subscapular bursa and synovial sheath of the long head of the biceps
What compresses the subacromial bursa? Where it it located?
Abduction of the shoulder and it is located between the acromion and head of humerus
Subacromial bursitis
Tenderness below acromion tip and pain with abduction +rotation and loss of smooth movement
Shoulder inspection
swelling, deformity, abnormal position, atrophy, color changes, skin alteration, fasiculations
Where to palpate the shoulder
A- anterior tip of the acromion
B- greater tubercle of the humerus
C- coracoid process
Shoulder Range of Motion
Flex extend ABduct ADduct Internal rotation (hands behind small of back) External rotation (hands behind neck)
Who is most likely to get “frozen shoulder”?
Diabeties
Sometimes hypothyroid, trauma
more likely in females
Medical name: adhesive capsulitis
To appropriately assess shoulder what 4 structures should be looked at?
- Acromioclavicular joint
- Subacromial + subdeltoid bursae
- Rotator cuff
- Biceps tendinitis
Test the acromioclavicular joint
Crossover or crossed body adduction test- Move pt’s arm across the chest
Test overall shoulder rotation
Apley scratch test
Difficulty w/ test suggests a rotator cuff d/o or adhesive capsulitis
Neer’s impingement
Press on pt’s scapula and raise pt’s arm
pain= positive test
possible inflammation or rotator cuff tear
Hawkin’s impingement
Flex pt’s shoulder+ elbow to 90 degress with palm facing down. Place one hand on the forearm and the other on the arm and rotate internally
pain=positive test
possible inflammation or rotator cuff tear
*test compresses the greater tuberosity against the coracoacromial ligament
