46
Q

Subscapularis Insertion

A

lesser tubercle of the humerus

47
Q

Subscapularis Action

A

shoulder MR

48
Q

Coracobrachialis Origin

A

coracoid process of the scapula

49
Q

Coracobrachialis Insertion

A

medial surface of the humerus near the midpoint

50
Q

Coracobrachialis Action

A

stabilizes the shoulder joint

51
Q

Humeral neck fracture

A

another injury caused by a fall on the outstretched hand

52
Q

Mid humeral fracture

A

caused by direct blow or a twisting force

53
Q

Radial nerve injury

A

Increased risk of injury because the nerve passes next to the bone in the spiral groove

54
Q

Pathological fractures

A

caused by benign tumors or metastatic carcinoma from primary sites such as the lungs, breast, kidney, and prostate

55
Q

Anterior shoulder dislocations

A

one of the most common joint dislocations involving the shoulder that is caused by a forced shoulder ADD and LR tends to be dislocation motion causing the humeral head to slide anteriorly out of the glenoid fossa

56
Q

Glenohumeral subluxation

A

commonly seen in individuals who have hemiplegia, usually from a cerebrovascular accident (stroke)

57
Q

Impingement syndrome

A

overuse condition that involves compression between the acromial arch, humeral head, and soft tissues structures

58
Q

Adhesive capsulitis

A

inflammation and fibrosis of the shoulder joint capsule which leads to pain and loss of shoulder ROM (frozen shoulder)

59
Q

Torn rotator cuff

A

involves the distal tendinous insertion of the supraspinatus, infraspinatus, teres minor, and subscapularis on the greater/lesser tubercle of the humerus

60
Q

Labral tear

A

Involves damage to the glenoid labrum that can have degenerative or traumatic etiology and results in pain and limited motion in the shoulder joint

61
Q

Calcific tendonitis

A

Chronic inflammation of the supraspinatus tendon can lead to an accumulation of mineral deposits and can be asymptomatic or painful

62
Q

Bicipital tendonitis

A

involves the long head of the biceps proximally as it crosses the humeral head, changes direction, and descends into the bicipital groove - a rupture of the biceps long head tendon commonly occurs during repetitive or forceful overhead positions

63
Q

Subluxing of the biceps tendon

A

overloading the muscle in an abducted and laterally rotated position tends to be the force subluxing the tendon out of the bicipital groove
