Path Interactive Session 11/13/23 Flashcards
Diff bet/ Rheumatoid Arthritis & Osteoarthritis
Rheumatoid - Autoimmune (hyper 2&3), Treat with Steroids
Osteoarthritis - Physical, Treat with NSAIDs
Why is it important to know diff between Rheumatoid and Osteoarthritis
Need to be mindful about infection and malignancies in regards to Rheumatoid b/c autoimmune
Osteoarthritis
Degenerative joint disease
primary characteristic of osteoarthritis
Degeneration of articular cartilage
- Joints scrapping away at each other (not necessarily inflammation
Primary and secondary osteoarthritis
primary - comes with age 95% of cases
secondary - Predisposing condition (trauma, dev. deformity, Marked obesity)
What is Chondromalacia
Soft texture and granular appearance of the articular cartilage surface
Further progressive changes in osteoarthritis
a) Cartilage thickness lost
b) Bone eburnation
c) Joint mice
d) Osteophytes
e) Pannus
Bone eburnation
polished ivory appearance of burnished bare bone
Joint mice
Small nodules of bone or cartilage fragment from articular surface and are loose in the joint space (may produce a sound)
Osteophytes
bony outgrowths at the margin of the articular surfaces
Pannus
Abnormal fibrovascular tissues seen in severe disease that cover the periphery of the articular surface
Pathogenesis of osteoarthritis
mostly wear and tear
Clinical findings Osteoarthritis
a) aching pain, stiffness, limited range of movement
b) Crepitis - grating or popping sound in joint
c) Osteophytes
- Compression of spinal nerves
- Heberdens nodes
- Bouchards nodes
d) Ankylosis (fusion) does not occur
Management of Osteoarthritis
- Lifestyle choices
- NSAIDS to narcotics
- Surgery (arthroscopy to joint replacement)
Gout
Disease of joints
- Overproduction or dec’d excretion of uric acid (end product of purine catabolism
