Osteoarthritis Vs Rheumatoid Arthritis Flashcards
OA Pathology
Degenerative joint disease with slow destruction of the articular cartilage
OA Inflammation
Asymmetrical
OA Age
53-64
OA Gender
Men and women are affected equally
OA Joints
Weight bearing (knees, hips, + fingers, hands, and wrists Swelling and edema, but no redness or “heat” complaints to joints Heberden’s nodes Bouchard’s nodes
Heberden’s Nodes
Distal interphalangeal joints
Bouchard’s Nodes
Proximal interphalangeal joints
OA Stiffness/Pain
Better in the morning; worse as the day progresses; aggravated by activity, relieved by rest
OA other findings
Genetic predisposition Increased incidence with age Obesity is an exacerbating factor Angular deformities affected joints Limited ROM Crepitus possible
OA Diagnostic
Labs - N/A
X-ray -Narrowing of the joint space, osteophytes, Juxta-articular sclerosis, subchondral bone
OA Management
ASA
Tylenol
NSAIDs
Cox-2 inhibitors (Celebrex)
OA supportive care
Weight loss Use canes on opposite side Ice Moist heat PT Refer for joint replacement
RA Pathology
Systemic autoimmune disease causing inflammation of connective tissue
RA Inflammation
Symmetrical
RA Age
35-50
RA Gender
Women 3:1
RA Joints
Proximal interphalangeal joints Metacarpal phalangeal joints Wrists Swelling and edema with redness and heat complaints to joint Ulnar deviation
RA stiffness/pain
Worse in the morning; better as the day progresses
RA other findings
Auto immune – multi factorial etiology Fatigue Weakness Malaise Anorexia Weight loss
RA Diagnostics
Labs: ESR usually elevated anti-nuclear antibodies positive in one out of five patients
Synovial aspirate with inflammatory changes and white blood cells
X-rays: Joint swelling, progressive, osteopenia, joint space narrowing
RA management
High-dose salicylates
NSAID
Disease modifying anti rheumatic drugs (DMARDs): Corticosteroids, methotrexate, antimalarial’s, gold salt injections
RA supportive care
Early rheumatologist referral
Rest
PT
Surgery
