Shoulder, Elbow, Wrist, Hand Flashcards
Acromioclavicular Joint-AC Joint
- Convex lateral end of clavicle on Concave acromion
- Acromioclavicular and Coracolavicular Ligaments attach acromion to lateral end of clavicle
Sternoclavicular Joint - SC Joint
-Medial end of clavicle is both convex: Superior/INF
—> Concave ant/post
-
Motion of Clavical
moves as a result of scapular elevation, depression, protraction and retraction
-rotates posteriorly when scap is upwardly rotated
Only bone attachment to axial skeleton
Scapulothoracic Joint
scap along thorax
1. Stability: achieved through the balanced forces of upper trap, levator scap, pec minor, rhomboids and serratus
What is Scaption?
30 degrees anterior to frontal plane
-functional position with less tension on the glenohumeral joint capsule
** Always look at spine of scap to decide if its an upward or downward rotation
glenohumeral joint
- convex head of humerus with concave glenoid fossa of scapular
- glenoid labrum increases joint congruence –> increase contact of head of humerus and glenoid
- labrum serves as an attachment for the joint capsule of the shoulder
Open pack position of Glenohumeral Joint
55 abduction
30 horizontal adduction
Closed pack of Glenohumeral Joint
full abduction and external rotation
Arthrokinematic motion of shoulder
CONVEX humeral head moving on CONCAVE glenoid fossa
what direction is the glide with the shoulder joint?
glide is in the opposite direction
Glide motions for Shoulder:
- extension
- flexion
- abduction
- ER
- IR
ext-ant glide
flex-post glide
abd-inf glide
ER- ant glide
IR- post. glide
2 glenohumeral ligaments
coracohumeral- coracoid process to greater tubercle
glenohumeral- covers ant. capsule
scapulohumeral rhythm
scap rotates 1 degree upward for every 2 degrees of total humeral movement
Starts at :
30 degrees of shoulder abd
60 degrees of shoulder flex
Neer’s impingement sign
GOAL: identify inflammation in subacromial space
POS: if there is pain
HOW:
pt. arm is passively forcibly flexed above head which decreases space btw. head of humerus and acromion process
Hawkins-Kennedy Impingement Test
GOAL: identify supraspinatus tendonitis
+ with pain
How:
pt. arm passively abducted 90 degrees and then forced into IR by therapist
Painful Arc
G: inflammation in subacromial space
+ pt has pain btw. 60-120 degrees of abd
H: pt. actively abducts against gravity
Speeds Test
G: bicep tendonitis
+ pain at bicipital groove
H: pt. forearm is supinated with elbow fully extended
Yergason’s Test
G: tendonitis of long head of bicep
+pain in bicipital groove
H: pt supinates forearm and ER shoulder against therapists resistance
Apprehension for Anterior Dislocation test
G: anterior glenohumeral joint instability
+ pt. demonstrates apprehension and prevents further movement of UE
H: pt. supine-> therapist passively abducts and ER shoulder
apprehension for posterior dislocation test
G: posterior glenohumeral joint instability
+ pt. demonstrates apprehension and prevents further movement of UE
How: pt. in supine and therapist passively flexes UE to 90 degrees and elbow to 90 degrees
-therapist passively IR UE and applies a posterior force to pt. elbow
Drop Arm Test
G: identify torn rotator cuff
+ unable to slowly lower arm or experiences pain
H: therapist passively abducts UE to 90 degrees and asks pt. to slowly lower arm
Empty Can Test
G: identifies supraspintatus tendon tear
+ patient has pain or weakness
H: pt. UE positioned horizontally @ 30 degrees ant. to the frontal plane with IR .
-therapist applies downward pressure
What is rotator cuff impingement
tendons compressed or pinched under coracoacromial arch
- mechanical compression=primary
- secondary= glenohumeral instability, weak muscles
clinical signs of rotator cuff impingement
+ hawkins-kennedy, painful Arc and Neers test
- pain& tenderness at supraspinatus tendon
- pain and weakness with abduction, flexion and ER
- traction to GH joint may decrease pain
pt. c/o:
- pain at night
- pain with overhead activities
