Arthritis




Degenerative Joint Disease
Arthritis= joint inflammation.
Arthralgia= joint pain
Different types of arthritis:



Osteoarthritis
Rheumatoid arthritis
Gouty arthritis
Osteoarthritis





Most common form of arthritis, noninflammatory,
nonsystemic disease
One or many joints undergo degenerative and
progressive changes, mainly wt. bearing joints.
Stiffness, tenderness, crepitus and enlargement
develop.
Deformity, incomplete dislocation and synovial
effusion may eventually occur.
Treatment: rest, heat, ice, anti inflammatory drugs,
decrease wt. if indicated, injectable corticosteroids,
surgery.
Osteoarthritis- Risk Factors






Age
Decreased muscle strength
Obesity
Possible genetic risk
Early in disease process, OA is difficult to dx
from RA
Hx of Trauma to joint
OA- Signs and Symptoms






Joint pain and stiffness that resolves with rest
or inactivity
Pain with joint palpation or ROJM
Crepitus in one or more joints
Enlarged joints
Heberden’s nodes enlarged at distal IP joints
Bouchard’s nodes located at proximal IP
joints
What to assess for:







ESR, Xrays, CT acans
Pain
Degree of functional limitation
Levels of pain/fatigue after activity
Range of motion
Proper function/joint alignment
Home barriers and ability to perform ADLs
Osteoarthritis- Tx







Pharmacotherapy- tylenol, NSAIDS, ASA, Cox-2
inhibitors
Intra-articular injections of corticosteroids
Glucosamine- acts as a lubricant and shock
absorbing fluid in joint, helps rebuild cartilage
Balance rest with activity
Use bracing or splints
Apply thermal therapies
Arthroplasty- joint replacement can relieve pain and
restore loss of function for patients with advanced
disease.
Auto-Immune Disease





Inflammatory and immune response are normally
helpful
BUT these responses can fail to recognize self cells
and attack normal body tissues.
Called an auto-immune response
Can severly damage cells, tissues and organs
EG. RA, SLE, Progressive systemic sclerosis,
connective tissue disorders and other organ specific
disorders
Rheumatoid Arthritis





Chronic, systemic, progressive inflammatory
disease of the synovial tissue, bilateral,
involving numerous joints.
Synovitis-warm, red, swollen joints resulting
from accumulation of fluid and inflammatory
cells.
Classified as autoimmune process
Exacerbations and remissions
Can cause severe deformities that restrict
function
RA- Risk Factors





Female gender
Age 20-50 years
Genetic predisposition
Epstein Barr virus
Stress
Rheumatoid Arthritis- Dx





Rheumatoid Factor antibody- High titers
correlate with severe disease, 80% pts.
Antinuclear Antibody (ANA) Titer- positive
titer is associated with RA.
C- reactive protein- 90% pts.
ESR: Elevated, moderate to severe elevation
Arthocentesis- synovial fluid aspirated by
needle
RA – Signs and Symptoms







Joints- bilateral and symmetric stiffness, tenderness,
swelling and temp. changes in joint.
Pain at rest and with movement
Pulses- check peripheral pulses, use doppler if
necessary, check capillary refill.
Edema- observe, report and record amt. and location
of edema.
ROM, muscle strength, mobility, atrophy
Anorexia, weight loss
Fever- generally low grade
RA- Sign and Symptoms
1. Fatigue- unusual fatigue, generalized weakness
2. Morning stiffness lasting longer than 30 minutes
after rising, subsides with activity.
3. Red, warm, swollen, painful joints
4. Systemic S&S
5. Pain- at rest and with movement
What should we monitor?
Rheumatoid Arthritis- Tx






Rest, during day- decrease wt. bearing stress.
ROM- maintain joint function, exercise –water.
Medication- analgesic and anti-inflammatory
(NSAIDS), steroids,Gold therapy, topical meds.
Immunosuppressive drugs- Imuran, Cytoxan,
methotrexate. Monitor for toxic effects
Biological response modifiers (BRM):Inhibit action of
tumor necrosis factor (Humira, Enbrel, Remicade)
Ultrasound, diathermy, hot and cold applications
Surgical- Synovectomy, Arthroplasty, Total hip
replacement.
Nursing Interventions





Assist with/encourage physical activity
Provide a safe environment
Utilize progressive muscle relaxation
Refer to support groups
Emotional support
Complications




Sjogrens’s syndrome
Joint deformity
Vasculitis
Cervical subluxation
Gouty Arthritis









Very painful joint inflammation, swollen and reddened
Primary-Inborn error of uric acid metabolism- increases production
and interferes with excretion of uric acid
Secondary- Hyperuricemia caused by another disease
Excess uric acid – converted to sodium urate crystals and
precipitate from blood and become deposited in joints- tophi or in
kidneys, renal calculi
Treatment:
Meds- colchicine, NSAIDS, Indocin (indomethacin), glucocorticoid
drugs,
Allopurinol, Probenecid-reduce uric acid levels
Diet- excludes purine rich foods, such as organ meats, anchovies,
sardines, lentils, sweetbreads,red wine
Avoid ASA and diuretics- may precipitate attacks

Erythematosus






SLE- Chronic Inflammatory disease affecting many
systems.
Women between 18-40, black>white, child bearing
years
Autoimmune process- antibodies react with DNA,
immune complexes form- damage organs and blood
vessels.
Includes: vasculitis; renal involvement; lesions of skin
and nervous system.
Initial manifestation- arthritis, butterfly rash,
weakness, fatigue, wt. loss
Symptoms and tx. depend on systems involved.
Systemic Lupus
Erythematosus
Pathologic changes-Autoimmune process
1. Vasculitis in arterioles and small arteries
2. Granulomatous growths on heart valves- non
bacterial endocarditis.
3. Fibrosis of the spleen, lymph node adenopathy
4. Thickening of the basement membrane of
glomerular capillaries.
5. 90% swelling and inflammatory infiltrates of synovial
membrane.
SLE
6. Renal- Lupus nephritis
7. Pleural effusion or PN
8. Raynaud’s phenomenon- about 15% cases
9. Neuro- psychosis, paresis, migraines, and
seizures
SLE Dx

elevation.
Orthopedic Injuries


Joint dislocation- out of joint. If not treated
promptly, avascular necrosis can occur.
Reduced- put back in place = closed
reduction. Neurovascular status- check.

Incomplete (Greenstick)-break occurs through only
part of the cross-section of the bone.
Closed Fracture (simple)- doesn’t break through the
skin.
Open fracture (compound) - extends through the skin
Comminuted- splintered into fragments
Depressed- fragment(s) is(are) indriven
Pathologic- through an area of diseased bone

Casts
Used to immobilize a body part so that a
fracture of a bone or dislocation can heal.
Pressure from hard casting materials can
produce complications such as:
 Pain
 Decreased sensation
 Skin breakdown
Casting materials- plaster or fiberglass.
Casts-Indications

Correct skeletal malformations.
Casts





While cast is drying, check C/M/S or NV status
hourly and then q4-8h
Circulation/ vascular checks- Warmth, color, pulses,
capillary refill, swelling.
Motion checks- ask pt. to wiggle fingers or toes.
Sensation checks- can pt. feel pressure, ask about
pain, this may detects if cast is too tight.
Check for odor and drainage
Electrical Bone Stimulation





Application of electrical current at fracture
site, invasive or non-invasive.
Stimulates osteogenesis to fracture site.
Invasive- inserts cathode to site.
Non-invasive- Coil encircles cast or skin,
attached to external generator, used 3-10
hrs. per day.
Contraindicated in presence of infection.
Factors inhibit fracture healing

2. Used to reduce, align, and immobilize fractures
3. Used to correct/prevent deformity
4. Tx of dislocated, degenerated, rutured
intravetebral discs and sc compression
Nursing goals:

Types of traction
1.
2.
3.
4.
Skin traction (straight) - Buck’s, Bryant’s,
pelvic girdle. The pull is transmitted to
muscle structure, indirect traction.
Skeletal traction – pins or wires inserted in
bone and attached to traction, may be used
to treat fractures of humerus, tibia, fibula
Continuous- for fractures
Intermittent- for back muscle sprains
Traction

Respiratory- pneumonia, exercise, ROM.
GI- high fiber diet, increased fluids.
Renal- to prevent stones- increase fluids.
MS- isometric exercises
Pain management
Diversion activities
5P’s Assessment for
Orthopedic Patients
Symmetric comparison:
 Pain- location, severity
 Pulse- distal to injury, check bilaterally.
 Parasthesias- numbness, tingling, compare
bilaterally. Sensaton check
 Pallor- check skin color and temp.
 Paralysis- Assess mobility, watch for foot
drop, compartment syndrome.
Documentation

High incidence in elderly due to risk for falls,
osteoporosis.
Intracapsular- fx. Neck of femur, may
damage blood supply, aseptic necrosis.
