Latissimus Dorsi Origin

spinous process of T7-L5, posterior surface of sacrum, iliac crest, and lower 3 ribs

Latissimus Dorsi Insertion

medial floor of bicipital groove of humerus

Latissimus Dorsi Action

shoulder extension, adduction, MR, hyperextension

Teres Major Origin

inferior axillary border of scapula near the inferior angle

Teres Major Insertion

medial lip of bicipital grood on the anterior surface of the humerus

Teres Major Action

shoulder extension, adduction, MR

Supraspinatus Origin

supraspinatus fossa of the scapula

Supraspinatus Insertion

greater tubercle of the humerus

Supraspinatus Action

shoulder ABD

Infraspinatus Origin

infraspinatus fossa of scapula

Infraspinatus Insertion

greater tubercle of humerus

Infraspinatus Action

shoulder LR, horizontal ABD

Teres Minor Origin

axillary border of scapula

Teres Minor Insertion

greater tubercle of humerus

Teres Minor Action

shoulder LR, horizontal ABD

Subscapularis Origin

subscapular fossa of the scapula

Subscapularis Insertion

lesser tubercle of the humerus

Subscapularis Action

shoulder MR

Coracobrachialis Origin

coracoid process of the scapula

Coracobrachialis Insertion

medial surface of the humerus near the midpoint

Coracobrachialis Action

stabilizes the shoulder joint

Humeral neck fracture

another injury caused by a fall on the outstretched hand

Mid humeral fracture

caused by direct blow or a twisting force

Radial nerve injury

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

Pathological fractures

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

Anterior shoulder dislocations

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

Glenohumeral subluxation

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

Impingement syndrome

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

Adhesive capsulitis

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

Torn rotator cuff

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

Labral tear

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

Calcific tendonitis

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

Bicipital tendonitis

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

Subluxing of the biceps tendon

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