MSK + rheumatology Flashcards
Clinical presentation of osteoarthritis
- F>M
- Obesity
- Large weight bearing joints
- Pain worsened with movement
- Stiffness on rest
- Bone swelling on fingers
Treatment of osteoarthritis
- Paracetamol (work up analgesic ladder)
- Cortisol injections
- Joint replacement
- Weight loss
Define rheumatoid arthritis
- Autoimmune disease
- Symmetrical
- Deforming

Diagnosis of RA
MORE THAN 6 WEEKS + MORE THAN 6 OF BELOW
1. Rheumatoid factor = +ve
2. Finger/hand/wrist involvement
3. Rheumatoid nodules
4. 3 or more joints
5. Morning stiffness
6. Erosion on x ray
7. Symmetrical
BLOODS
