Arthritides + Rheumatology Flashcards
What are arthritdes
Disease that affects bones on both sides of the jt and narrows the space between them
What is the favoured type of jt for arthritides
Synovial jts
What are the 4 categories of arthritis
- Degenerative
- Inflammatory
- Metabolic
- Infectious
typical age of onset for degenerative arthritis (primary and secondary)
primary- 40+
Seconday- 25+ (prior trauma, deformity etc)
clinical features of degenerative arthritis (+ how long does stiffness last)
stifness lasts less than an hour
-may be symptom free OR gradual progressive onset of pain/decreased ROM
Clinical features of inflammatory arthritides
Morning stiffness > 1 hr
-jt inflammation, rapid onset, variable age range, flares and remissions
What are the clinical features of metabolic arthritides
symptoms/ age variable
usually deposition of crystals in/near jt
what is the typical prsentation of jt involvement in degenerative conditions
non uniform jt space narrowing + asymetrical distribution
What is the typical presentation of jt involvemnt in inflammatory conditions
uniform jt space narrowing and symetrical dystribution
What is an osteophyte and what is it associated w (/how does it present)
associated with degeneratibe arthritides
-always starts w a horizontal component
What is a syndesmophyte
Inflammtory ossification within a spinal lig or peripheral annular fibre of the disc
*vertical component always
What is an enthesopathy
Condition of the enthesis (site of tendon/lig attachment @ bone) where there is a degenerative tug response
What is enthestitis
Inflammtiory cellular inflitrate at these sites- seen as cortical erosiion and periostitis
-Usually painful!
when will you see erosison of the bones
loss of bone due to active bone breakdown or pressure
-associated with inflammmatory or certain metabolic arthropathies
