|
most characteristic erosive joint disease
higher incidence in OA and women cause is unknown it CAN'T be diagnosed without hands and feet |
|
|
3 phases of rheumatoid arthritis
|
-infiltration of sinovial memberane by cells derived from bone marrow
-amplification phase -chronic inflammation with unregulated cytokine production, leading to formation of abnormal sinovial membrane which encroaches across the joint, release of bone destroying enzymes and increased vascularisation |
|
|
Things that characterize rheumatoid arthritis
|
-cortical destruction
-undercut edges -exposed trabecular bone -sharp or scalloped ridges -a scooped floor Post-mortem damage is a different color -can see some remodelling on an x-ray |
|
|
Erosive osteoarthritis
|
-Almost exclusively in women and often agressive
-Most often confined to hands and frequently interphalangeal -Sacro-iliac joints not affected, no spinal involvement Presence of eburnation in any hand joints AND asymmetrical central erosions of pips and dips, and the 'gull wing' and/or 'saw tooth' may be present in an x-ray |
