8

A 20 YO dancer reports decreased plantar flexion and decreased sensation to the back of her thigh, calf, and the lateral half of her foot. What nerve is involved?

Tibial nerve

9

Describe what’s happening:
Chondrocytes lay down a cartilage frame of bone, where osteoclasts and osteoblasts later lay down bone matrix. Occurs mostly in the axial skeleton and the limbs. Also, if there is a defect to this system, what pathology results?

Endochondral ossification - Achondroplasia

10

Describe what’s happening: osteoblasts and osteoclasts lay down a bone frame, without the cartilage matrix, as in the skull and facial bones.

Membranous ossification

11

The following describe a bone neoplasm:
-Benign
Less than age 25
Chunk of bone appearance
What pathology is at hand?

Osteochondroma

12

The following describe a bone neoplasm:
-Malignant
-Age 10-20 years old
-Codman’s Triangle
-Sunburst appearance on X-ray

What pathology is at hand?

Osteosarcoma

13

The following describe a bone neoplasm:
-Malignant
-Less than 15 years of age
-Onion skin on XRay

What pathology is at hand?

Ewing Sarcoma

14

The following describe a bone neoplasm:
-Benign
-Age 20-40 years old
-Soap bubble appearance on X-ray

What pathology is at hand?

Osteoclastoma

15

Different cancers can make blastic or lytic lesions... what makes blastic and what makes lytic lesion?
-Lung
-Prostate
-Breast

Lung—> lytic lesions (can cause hypercalcemia in lytic lesions)
Prostate —> blastic lesions
Breast —> lytic or blastic

16

What are the 4 muscles of the rotator cuff???

SItS:
-Supraspinatus
-Infraspinatus
-teres minor
-Subscapularis

17

What muscle initiates abduction of the arm?

Supraspinatus

18

What two muscles rotate the arm laterally or externally?

Infraspinatus and teres minor

19

What muscle moves the arm to perform internal rotation?

Subscapularis

20

What class of antibiotics increase the risk of tendonopathy and tendon rupture in adults?

Fluoroquinolones - rare, but increased risk of Achilles’ tendon rupture

21

What do you think of when you have a (+) anterior drawer sign?

ACL injury

22

In osteoarthritis, what is the name for inflammation in the proximal interphalangeal joints are called what? X-ray findings show decreased joint space narrowing.

Bouchard’s nodes

23

In osteoarthritis, what is the name for inflammation in the Distal interphalangeal joints are called what? X-ray findings show decreased joint space narrowing.

Heberden’s Nodes

24

Rheumatoid arthritis is what kind of hypersensitivity?

Type III - auto antibodies that bind to soluble antigens in the blood that form immune complexes that gets deposited in tissues.

25

Swollen, hard, painful finger joints is:

Osteoarthritis

26

Swollen, boggy, painful finger joints is:

Rheumatoid arthritis

27

Cartilage erosion with polished bone beneath is:

Osteoarthritis —>”ebernation” of the bone

28

What is the triad of Sjögren’s syndrome? What are the antibodies associated?

Dry eyes (xerophthalmia)
Dry mouth (xerostomia)
Arthritis
Anti-SSA (Anti-Ro), and Anti-SSB (Anti-La)
(+)rheumatoid factor

*Sicca symptoms doesn’t necessarily mean Sjögren syndrome:
Dry eyes, dry mouth, nasal dryness, vaginal dryness, chronic reflux, chronic bronchitis, reflux esophagitis

29

This disease is associated with an X-linked frameshift mutation causing a DELETION of the dystrophin gene, causing acceleration of muscle breakdown and elevated CK. Typically presents very early in life (>5) with weakness in pelvic girdle muscles, that progress superiorly. There is pseudohypertrophy of calf muscles due to replacement of muscle with fibrofatty tissue. Shows “Gowers” maneuver. What pathology is at hand?

Duchenne Muscular Dystrophy

30

This pathology causes a MUTATION in the dystrophin gene, so less severe, and with later onset, seen in adolescence or early adulthood. What disease is at hand?

Becker muscular dystrophy
