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

    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

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.

 Decreased sensation

 Skin breakdown

Casting materials- plaster or fiberglass.
Casts-Indications
   Provide protection and healing of fractures
   Maintain therapeutic alignment- body parts
   Protect soft tissue injuries

   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

     muscle structure, indirect traction.
2.   Skeletal traction – pins or wires inserted in
     bone and attached to traction, may be used
     to treat fractures of humerus, tibia, fibula
3.   Continuous- for fractures
