Final - Arthritis Overview Flashcards
What is HADD?
Hydroxyapatite Deposition Disease
Causes calcific tendinosis
What is CPPD?
Crystal Deposition Disease (Calcium Pyrophosphate Dihydrate)
Causes chondrocalcinosis
What Which two types of arthritis have uniform joint space loss?
Infectious and inflammatory
Which type of arthritis is characterized by capsular joint distension?
Infectious
Which type of arthritis has subchondral sclerosis, cysts and osteochondral bodies?
Degenerative
Which types of arthritis cause a loss of subchondral bone?
Infectious and inflammatory
What four types of arthritis fall under the category of degenerative?
OA, DISH, snoviochondrometaplasia, neuropathic arthritis
T or F: DISH can have large impact on disc space height
False
Doesn’t affect discs
Which type of arthritis is very destructive and corresponds to the 6 Ds?
Neuropathic arthritis
Which arthritis has multiple intraarticular osteochondral bodies?
Synoviochondrometaplasia
Which type of arthritis shows gull-wing deformity in the phalanges?
EOA
Which two arthritis types show juxtaarticular osteopenia? Which shows sclerosis?
Inflammatory and infectious
Degenerative
What are the seronegative spondyloarthropathies and what location on the body do they all affect?
Reiter’s, Psoriatic, AS, Enteropathic
SI joint
Which two arthritis can cause DIP/PIP degeneration and coarse syndesmophytes? Symmetric or asymmetric sacroiliitis?
Psoriatic and Reactive arthritis
Asymmetric
Are actual joint changes common in scleroderma and SLE?
No, it is unlikely that you will see any radiographic changes
3 characteristics of Hypertrophic Osteoarthropathy
- Digit clubbing
- Joint pain, swelling
- Bilateral periosteal response
What joint condition causes overhanging margins?
GOUT
In which condition does pain and stiffness last longer during episodes, DJD or inflammatory arthritis?
DJD <1.2 hour
RA >1hour
RA should last quite a bit longer
What hand/foot joints is psoriatic arthritis likely to affect?
DIPs
T or F: DJD is characterized by erosions
False
What seronegative spondyloarthropathy has thin syndesmophytes?
AS
PA and RA have coarse syndesmophytes
DJD and bony changes vs inflammatory bony changes
DJD= osteophytes, sclerosis
Inflammatory= syndesmophytes, osteopenia
M/C locations of CPPD?
Knee
Wrist
Pubic Symphysis
M/C locations for HADD?
Shoulder
Hip
Definition of syndesmophytes?
Calcification of paraspinal periarticular soft tissue
Definition of enthesophyte?
Calcification of tendon or ligament insertion
If all 3 joints n a single digit is inflamed (“ray pattern”), what kind of arthritis would you suspect?
Psoriatic arthritis
Which two inflammatory arthropathies cause bilateral, symmetrical sacroiliitis?
AS and enteropathic arthritis
Which two conditions cause unilateral or bilateral asymmetrical sacroiliitis?
Psoriatic and reactive arthritis
T or F: RA, DISH and DJD all commonly affect the SI joint
False
Which arthritis condition may have marginal syndesmophytes but it is less common?
Enteropathic arthritis
Atlanta-axial instability is seen in these three arthritic conditions
RA
AS
PA
Which condition exhibits reversible hand deformities?
SLE
Which arthritic condition exhibits triangular sclerosis of the iliac portion of the SI joints without showing evidence of erosion?
Osteitis Condensans Ilii
What are the 6 D’s of neuropathic arthritis?
Distended joint Decreased density Debris Dislocation Disorganization Destruction
What tissues are involved in DISH and where?
Usually ALL. Upper Lx, throughout Thx and lower Cx.
Can also affect pelvis, patella, calcaneous, elbow and superior SI joint.
T or F: facets are usually involved with DISH
False
What metabolic disease is commonly associated with DISH?
Diabetes
T or F: erosions, bilateral symmetry and uniform joint space lost are common in certain inflammatory arthropathies
True
