[hunteradam07]

One is non-inflamatory-OA and inflamation is hall mark of RA. RA involved non weight barring joints and usually bilateral ie: PCP, wrist, and C1/2 complex in cervical spine. Furthermore, ankylosis is common with RA. While OA is usually unilat and weight barring joints like DIP, hips, and knees. And it's not ankylosis. Of course Pannus formation and erosion of the joints are hallmarks of RA. Oh side notes, patients with RA should be careful when he or she gets adjustment from chiropractors or any cervical manipulation due to unstable c1-2 erosion.
