1

What are the 8 categories of bone disease?

Congenital
Arthritis
Trauma
Blood (hematological)
Infection
Tumor
Endocrine, nutritional, metabolic
Soft Tissue
(CATBITES)

2

Which is associated with a symmetric pattern of uniform loss of joint space that is accompanied by soft tissue swelling, edema, and erosions: OA or RA?

RA

3

Which is associated with an asymmetric pattern of nonuniform loss of joint space that is accompanied by osteophytes, subchondral sclerosis, and cysts: OA or RA?

OA

4

What is overall the most common pathology of the spine?

Degenerative joint disease

5

What is unique about the destruction associated with metabolic joint disease?

Joint space is usually spared (compare to RA and OA)

6

What other kind of joint disease can usually be associated with a metabolic disease like gout?

DJD

7

Which type of arthritis is called the "lumpy bumpy arthritis"?

Metabolic

8

What is the most common organism to cause an infectious/septic arthritis?

Staph. aureus

9

What is unique about the distribution pattern of infectious/septic arthritis?

Usually monoarticular

10

How much bone must be destroyed to be able to see it on X-ray?

30-50%

11

How much bone must be destroyed to be able to see it on a bone scan?

3%

12

Which arthritis is most likely to occur in those aged 0-20?

Juvenile Rheumatoid Arthritis (JRA)

13

Which arthritis is most likely to occur in those aged 20-40?

Seronegative or seropositive (inflammatory) conditions

14

Which arthritis is most likely to occur in those aged 40+?

Degenerative, DISH, gout, CPPD

15

What is the term for a surgical fusion? Congenital? Pathological?

Surgical = arthrodesis
Congenital = synostosis
Pathological = ankylosis

16

What are the ABCDS of joint diseases?

Alignment
Bone
Cartilage
Distribution
Soft tissue

17

What is the technique used to assess for joint disease more accurately than X-ray?

Scintigraphy (bone scan)

18

Why is the law of parsimony applied to the study of joint diseases?

Patients with one arthropathy will most likely eventually present with another which can complicate the physical findings

19

What is the most common cause of a neurotrophic arthropathy?

Diabetes

20

What are neurotrophic arthropathies (aka Charcot joints)?

Diseases resulting from a loss of proprioceptive and sensory function (inability to sense pain)

21

What is the usual distribution for a neurotrophic arthropathy?

Monoarticular

22

What are the two categories of neurotrophic arthropathies?

Hypertrophic (bone forming) and atrophic (resorptive)

23

Non-weight bearing joints are more likely to be affected by what category of neurotrophic arthropathies?

Atrophic (resorptive)

24

Weight bearing joints are more likely to be affected by what category of neurotrophic arthropathies?

Hypertrophic

25

What is unusal about the pain symptoms of patients with neurotrophic arthropathies?

Only 30% will have pain thus making diagnosis difficult

26

What are the 6 D's of radiographic findings of neurotrophic arthropathies?

Distended joints, density increase, debris, dislocation, disorganization, destruction

27

What are the common areas for neurotrophic arthropathies?

Feet, knees, spine

28

What is the condition involving Charcot's joints of the knees and lumbar spine?

Tabes dorsalis

29

Are hypertrophic Charcot's joints more likely to occur n the upper or lower extremities?

Lower (weight-bearing joints)

30

What is the location of a Lisfranc's joint?

Tarsometatarsal articulation
