Duke PA Radiology of Arthritis
Question | Answer |
---|---|
joint space narrowing, sclerosis, osteophytosis | three hallmarks of OA |
OA in the hands has a __ predominance | distal |
OA results from | trauma |
OA is __ | non-inflammatory |
AC, TMJ, SI, Symphisis pubis | joints where you will see erosions with OA |
You normally don't see __ in OA, except in 4 specific joints | erosions |
geode | subchondral cyst |
normal finding in OA | geode/subchondral cyst |
OA without joint space narrowing, and sclerosis, but only osteophytes | DISH |
Diffuse Idiopathic Skeletal Hyperostosis | DISH |
RA is a __ disease | systemic inflammatory |
RA is a disease of | erosions |
distribution of RA is | proximal and symmetric |
soft tissue swelling, osteoporosis, joint space narrowing, marginal erosions | hallmarks of RA |
in extension and flexion veiws of the C spine if you see increased distance between the dens and the anterior arch of C1 you have | Atlantoaxial Instability with RA |
Can cause compression of the C spine | Atlantoaxial Instability with RA |
Ankylosing Spondylitis behaves like | Inflammatory Bowel Disease |
Psoriatic Arthritis behaves like | Reiter Syndrome (reactive srthritis) |
Ankylosing Spondylitis, inflammatory bowel disease, psoriatic arthritis, reiter syndrome | Seronegative spondyloarthropathies |
in patients with spinal ankylosis even a minor trauma | can be a huge disaster |
bony ankylosis, new bone formation, axial spine involvement | hallmarks of seronegative spondyloarthropathies |
syndesmophytes and ankylosis | bamboo spine |
if you have asymmetric arthritis involvement of the SI joints | it is not ankylosing spondylitis, or IBD |
can't see, can't pee, can't climb a tree | Reiter Syndrome |
arthritis, nongonococcal urethritis, conjunctivitis | Reiter Syndrome |
often follows a GU or GI infection | Reiter Syndrome |
Ankylosing spondylitis must be | symmetric |
distal predominance, soft tissue swelling, periostitis, proliferative erosions with fuzzy margins | Hallmarks of Reiter syndrome and Psoriatic Arthritis |
deposits of monosodium urate crystals in a joint | gout |
it takes 4-6 years for radiographic evidence to occur with __ | gout |
gout of the great toe | podagra |
well defined sclerotic erosions, soft tissue nodules, random distribution | gout |
has the same clinical manifestations as gout but is caused by calcium pryrophosphate dihydrate deposition | pseudogout |
has weird DJD locations (shoulder, elbow, radiocarpals, MCP | pseudogout |
__ is associated with primary hyperparathyroidism, gout, hemochromatosis | pseudogout |
pain, cartilage calcification (chondrocalcinosis), joint destruction | pseudogout |
knee, triangular figrocartilage of wrist, pubic symphysis | common CPPD chondrocalcinosis sites |
the worst joint you will ever see | neuropathic (Charcot) joints |
inaccurate muscle action and loss of reflexes | neuropathic (Charcot) joints |
seen in diabetes, paralysis with continued limb use, tabes dorsalis of syphilis | neuropathic (Charcot) joints |
destruction, dislocation, heterotopic new bone-debris or detritus | neuropathic (Charcot) joints |
most common neuropathic joint | Lisfranc Charcot Joint |
Inflammation of synovial membrane with purulent effusion | septic arthritis |
treat __ urgently | septic arthritis |
Fever and hot, red, painful, distended joint with decreased range of motion Rapid Complications--Joint destruction, Osteomyelitis, Sepsis, and even Death | septic arthritis |
most common site for septic arthritis in adults | knee |
most common site for septic arthritis in children | hip |
x-ray of joint with septic arthritis | often normal |
elbow effusion + trauma = __ | fracture |
joint pain + effusion = __ | septic arthritis |
if you see a posterior fat lucency on the elbow it is an | effusion |
the anterior fat pad in the elbow should | hug the bone |
if the elbows anterior fat pad is not hugging the bone but is giving the sail sign it is __ | an effusion |
Osteonecrosis from Steroids, Trauma, Sickle Cell Disease, Idiopathic | avascular necrosis |
effusion, patchy sclerosis in otherwise normal joint, subchondral lucency, collapse of articular surface and fragmentation | avascular necrosis |
Inflammatory Granulomatous Disease,Bone Manifestations:Destructive lytic lesions, lace-like appearance | sarcoid |
osteoporosis, soft tissue wasting | collagen-vascular disease |
best imaging modality for arthritis | plain films |
