_____: hypertrophic unicinate processes Occur in the ______ category
pseudo-fractures occur in: degenerative category)
cc_______: degeneration of the outer ortion of the annulus fibrosis, identified by marginal osteophytes
spondylosis deformans (when the adjacent vert. is involved = Intervertebral chondrosis) degenerative category
cc_________: Ca+ at at least 4 conti vert location: anterior to the A.L.L ______ category
Diffuse Idiopathic skeletal hyperostosis (DISH) - there is a preservation of disc space degenerative category
cc________: involves villi. Villi hypertrophies and breaks off = loose body
Synoviochondrometaplasia
cc______: anything that affects the nervous input to the jt = there is no feeling in that jt
neurotrophic arthopathy 2 types: 1. hypertrophic arthropathy 2. Atrophic arthropathy
name the 6 D’s of Hypertrophic arthropathy
- distention- swelling of the jt 2. debris 3. dislocation 4. density increase 5. disorganization 6. destruction
Atrophic arthropathy occurs following an ______
infection “licked candy stick” ex: leprosy
_________:Triangular shaped sclerosis of the iliac side of the SI jt → incr in bone density
Osteitis Condensans Ilii (MC: women- changes to pelvis during pregnancy)
what is pannus formation? What dx is it seen in_____
waste product of the tiss. in the area - occurs at: transverse lig= instability at the atlanodental region DX: RA
anteriolisthesis aka ______ Dx: _____
Stepladder (loss of disc ht, C2-C4) Dx: RA
Stelle’s Law of Thirds
1/3rd: ring taken up by the dens 1/3rd: of the space is taken up by the SC 1/3rd: of the space is taken up by everything else
What is the MC type of Juvenile Idiopathic arthritis
Still’s dx (RF Neg) - polyarticular
What is the path of AS
T/L jxn–> SI –> Neck
Explain the difference btw: 1. Bamboo spine 2. Dagger sign 3. Trolly track
- bamboo: Undulating vert. contour 2. Dagger: single central radiodense line (supraspinous & interspinous lig) 3. Trolley: 3 vertical radiodense lines (interspinous lig, supraspinous lig, and apophyseal jt capsule)
cc______: has shiny corners and squaring of the vert. bodies
AS
“Mouse Ear” fluffy periosteal rxn at the margins
Psoariatic arthritis (also has Pencil in cup) (inflammatory category)
What does C.R.E.S.T stand for? what dx:
C: calcinosis R: Raynaud’s E: Esophageal dysmotility S: Sclerodactyly T: Telangiectasia Dx: Scleroderma (inflammatory category)
_______dx: inflammation and degeneration of M and Skin with ass. soft tiss Ca+ - Ca+ starts to outline where the border of skin is
Polymyositis (M) or Dermatomyositis (skin + M) (inflam category)
cc_______: GH hypersecretion due to pituitary adenoma
Acromegaly
pseudo gout aka _____
Calcium pyrophosphate deposition disease (CPPD)
cc_______: has linear Ca+ in hyaline or fibrocartilage Category: _____
Calcium Pyrophosphate Deposition Disease (CPPD) deposition
______: deposition of Ca+ in the tendon or capsule (usually follows trauma)
Hydroxyapatite Deposition Disease (HADD)
purine metabolism disorder
Gout
_____ condition has an “ overhanging edge sign”
Gout (tophus formation)
_______ condition has a lack of homogentisic acid oxidase
Ochronosis (alkaptonuria) leads to Ca+ of disc and other CT (it looks like AS, but also has Ca+ in the disc space)
______: noncaseating granulomas, subcutaneous nodules
Sarcoidosis Appearance: • honeycomb: lucent changes • lace or lattice-like trabecular pattern of destruction • Acro-osteolysis: distal bone break down • Cystic Defects
Which condition has “honey comb” lucent changes
sarcoidosis
during ______ condition you will see Acro-osteolysis (distal bone break down)
sarcoidosis
cc______: Vascular supply to an osseous structure is diminished / eliminated
