12
Q
Intervertebral Osteochondrosis
A
DJD
- targets nucleus pulposis
- vacuum phenomenon of IVD
- decreased IVD height
13
Q
Spondylosis Deformans
A
DJD
- targets annular fibers
- osteophytes of vertebral endplates
14
Q
Degenerative Spondylolisthesis
A
DJD
- pars intact
- vertebrae moves foreward secondary to degenerative remodeling of posterior joints
15
Q
Hemispherical Sclerosis
A
DJD
- reactive sclerosis of vertebral body adjacent to degenerative disc
- often with schmorls nodes
16
Q
Spinal Stenosis
A
DJD
- bony overgrowth and soft tissue hypertrophy
- narrowing of cord
- thickened ligamentum flavum
- capsular thickening of zygopopyseal
17
Q
Degenerative Spondylolisthesis
A
DJD
- posterior elements not separated from body
- most common L4/5
18
Q
DJD hip
A
- narrowing of SI superolaterally
- unilateral or bilateral
- most common joint for geode formation
19
Q
DJD AC joint
A
- supraspinatus
- impingment syndrome
20
Q
DJD hands
A
- heberdens (DIP)
- bouchards (PIP)
21
Q
DJD knee
A
- asymetrical narrowing
- osteophytes
- geode possible
22
Q
DISH
A
DJD
- 4 contiguous segments
- anterior or lateral thick calficiaition of ALL
- relatively normal disc height
- periphreal involvement includes calcaneal osteophyes and hypertrophic margin of glenoid fossa
23
Q
OPLL
A
DJD
- cervical spine most often
- isolated phenomenon or assoc with DISH
- cervical cord compression
- upper motor neuron findings
24
Q
Osteitis Condensans Illi
A
DJD
- multi parous female
- resolves w/ age
- most often bilateral
- triangular pattern of sclerosis but no fusion
25
Ankylosing Spondylitis
- seronegative DJD, inflammatory
- large extremities affected
- forward posture, exaggerated kyphosis
- widened SI, but then eventual fusion
- star sign at iliolumbar lig insertion
- syndesmophytes
- enthesopathy
- shiny corner sign- squared off appearance of body
- bamboo spine- late stage
26
syndesmophyte
- happens with ankylosing spondylitis, seronegative DJD
- thin, vertebral bilateral calcific density at joint margin
- what makes it look like bamboo spine on the sides of body
27
enthesopathy
- indicative of OA
| - inflammation of ligament and tendon insertions
28
Psoriatic Arthropathy
- seronegative DJD, inflammatory
- likes DIP
- asymmetrical joint swelling
- mouse ear erosions
29
Reactive Arthritis
- inflammatory
- eyes, urinary tract, lower extremities
- lovers heels (calcaneal osteophytes)
- syndesmophytes in spine
- marginal erosions
- diffuse joint narrowing
30
Rheumatoid Arthritis
- inflammatory
- swan neck deformity ( ulnar drift of MCs_
- uniform loss joint space
- protrusio acetabuli
- ottos pelvis (bilateral protrusio acetabuli)
- pannus formation in spinal canal
31
Synovial Chondrometaplasia
- osteochondral bodies that calcify
- large joints
- monoarticular
32
Gout
- crystal deposition arthropathy
- monoarticular
- SED elevated
- many episodes until xray findings
- large erosion of joint margin
- overhanding edge
- soft tissue calcification
33
CPPD
- can mimic DJD and gout
- deposits in hyaline cartilage
- typically bilateral
- parallel calcifications along articular margins
- geode common
34
HADD
- calcific tendonitis
- supraspinatus usually
- near insertion
