Shoulder injuries

Question 1

what is most common nontraumatic cause of shoulder pain?

Answer 1

impingement syndrome

Question 2

impingement syndrome results from what?

Answer 2

approximation of acromion and greater tubercle of humerus causing entrapment of rotator cuff tendons

Question 3

Primary factor of impingement syndrome

Answer 3

muscualr imbalance at shoulder exacerbated by external rot muscles weakness and highly trained IR muscles

Question 4

Impingement syndrome can lead to what?

Answer 4

postural abnormalities such as ant shoulder carriage w/ excessive IR (shoulder rounded fwd)

adaptive shortening and fibrosis of IR

inflamed RC tendons

Question 5

Most common factor for chronic RC disorders

Answer 5

progressive loss of ER due to fibrosis or adaptive shortneing of IR

Question 6

PREdisposing factors for impingement syndrome

Answer 6

biomech unsound exs
sports like swimming
lifting wts w/ poor form
training same area too often (overtraining ant delt, pec major, and lats)

Question 7

Treatment of impingement syndrom is heavlily focused on what and includes?

Answer 7

retraining proper exs and posture, which includes strengthening and improving F(f) of ERs, stretching IRs, and eliminating training errors that started the dysfunction in first place

Question 8

what is primary factor of impingement syndrome?

Answer 8

muscular imbalance at shoulder exacerbated by External RC muscles and highly trained internal Rot muscles (prime movers)

Question 9

Thoracic outlet syndrome is related to what factors?

Answer 9

biomechx, poor posture, and shoulder muscle imbalance

Question 10

TOS is what?

Answer 10

Thoracic outlet syndrome is compression of neurovascular bundle (brachial plexus and axillary artery/vein) in axillary region

Question 11

Thoracic outlet syndrome RESULTS IN WHAT SYMPTOMS?

Answer 11

pain, numbness, and tingling in upper extremity usually in 4th and 5th digits of hand

Question 12

3 sites of compression in Thoracic outlet syndrome:

Answer 12

between first rib and anterior scalene muscle

pec minor muscle or clavicle

Question 13

How is Thoracic outlet syndrome treated??

Answer 13

correcting fauly biomechancs, strengthening RC,and stretching shoulder IR and scalenes

Question 14

GH dislocation occurs anteriorly due to

Answer 14

capsular tears

Question 15

Mech of GH JT dislocation is what?

Answer 15

excesive abd, ext rot, and extension of shoulder

Question 16

What should be done if suspected GH Jt dislocation?

Answer 16

stabilize shoulder is vital to prevent any further damage, particularly neurological structures

Question 17

Answer 17

direct blow to shoulder or falling on outstrectched arm

Question 18

S and S of AC jt sep

Answer 18

elevation of the distal clavicle and sharp pain in jt

Question 19

RC tendon tears (supraspin) can be cuased by what?

Answer 19

forceful throwing and improper weight-lifting technqiues
