Ch. 5 Humerus and Shoulder Girdle Pathology

Question 1

trauma to the upper shoulder region resulting in a partial or complete tear of the AC or coracoclavicular (CC) ligament or both ligaments

Answer 1

AC joint speration

Question 2

injury in which the distal clavicle usually is displaced superiorly

Answer 2

acromioclavicular dislocation

Question 3

injury of the anteroinferior aspect of the glenoid labrum; caused by anterior dislocation of the proximal humerus

Answer 3

Bankart lesion

Question 4

inflammation of the bursae, or fluid filled sacs enclosing the joints

Answer 4

bursitis - shoulder is most common joint to develop it

Question 5

compression fracture of the articular surface of the posterolateral aspect of the humeral head that often is associated with an anterior dislocation of the humeral head

Answer 5

Hill-Sachs defect

Question 6

disability of the shoulder joint that is caused by chronic inflammation in and around the joint. characterized by pain and limitation of motion

Answer 6

idiopathic chronic adhesive capsulitis (frozen shoulder)

Question 7

impingement of the greater tuberosity and soft tissues on the coracoacromial ligamentous and osseous arch, generally during abduction of the arm

Answer 7

impingement syndrome

Question 8

noninflammatory joint disease characterized by gradual deterioration of the articular cartilage with hypertrophic bone formation; most common type of arthritis

Answer 8

osteoarthritis; degenerative joint disease (DJD)

Question 9

reduction in the quantity of bone or atrophy of skeletal tissue; occurs in postmenopausal women and elderly men

Answer 9

osteoporosis

Question 10

chronic systemic disease characterized by inflammatory changes that occur throughout the connective tissues of the body; occurs more frequently in women than men

Answer 10

rheumatoid arthritis

Question 11

acute or a chronic traumatic injury to one or more of rotator cuff muscles; limits the range of motion of the shoulder

Answer 11

rotator cuff pathology/tear

Question 12

traumatic removal of the humeral head from the glenoid cavity; 95% are anterior

Answer 12

shoulder dislocation

Question 13

a bony fragment is wedged into another fragment, common in shoulder and hip fractures

Answer 13

impacted fracture

Question 14

fracture involving the joint surface

Answer 14

articular fracture

Question 15

fracture due to bone destruction caused by disease, cancer is the primary cause

Answer 15

pathologic fracture

Question 16

a fracture accompanied by a bone out of a joint

Answer 16

fracture dislocation

Question 17

distal calvicale is usually displaced superiorly causing widening of the AC joint space

Answer 17

AC dislocation

Question 18

inflammatory condition of the tendon

Answer 18

tendonitis

Question 19

dislocation of a bone from a joint

Answer 19

luxation

Question 20

partial dislocation

Answer 20

subluxation
