Chapter 65: Med Surg Flashcards
osteoarthritis
slowly progressive noninflammatory disorder of synovial joints r/t age, genetics, obsesity, frequent kneeling, lack of exercise
Men with OA
men after more often affected than women before age 50, hip OA more common after 55, knee OA more common in men before age 45
women with OA
affected more after age 50 thought to be caused by estrogen reduction at menopause
OA results from
cartliage damage leading to cartilage and bony growth increasing at joint margins causing uneven distribution of stress across joint and reducing motion
s/s of OA
no systemic (unlike RA!), joint pain and may be referred to groin, butt, thigh or knee, early morning stiffness but resolves within 30 min
heberden’s nodes
occur in distal interphalangeal joints as an indication of osteophyte formation and loss of joint space, red, swollen, tender
bouchard’s nodes
affects proximal interphalangeal joints, red, swollen, tender
diagnostics of OA
bone scan, CT, MRI detect early joint changes and x rays confirm disease and stage progression such as joint space narrowing and osteophyte formation, synovial fluid clear yellow and not inflammed (unlike RA!)
tx of OA
managing pain, preventing disability, and maintaining and improving joint fx, rest should not exceed 1 week, heat used more than ice, arthroscopy to repair cartilage or remove bone bits
alternative therapy of OA
glucosamine and chondroitin sulfate helpful in resolving moderate to severe arthritis pain and improving joint mobility
drug therapy for OA
tylenol 1000 mg q6h do not exceed 4 g/day, Zostrix topical cream, no NSAIDs with Coumadin or anticoagulants or Aspirin
hyaluronic acid
viscosupplementation contributes to viscosity and elasticity of synovial joints
spondyloarthropathies
inflammatory disorder that affects the spin, peripheral joints, negative for rheumatoid factor, HLA-B27 gene associated, difficult to distinguish types early in disease
ankylosing spondylitis
chronic inflammatory disorder affecting axial skeleton, highest incidence 25-34 yeras of age, men more likely to develop
s/s of ankylosing spondylitis
low back pain, stiffness, limitation of motion, pain in other areas such as hands, extraarticular inflammation in eyes, lungs, heart, etc
diagnostics for ankylosing spondylitis
pelvic x ray is essential for characteristic changes of sacroiliitis, may see “bamboo spine” which is the result of calcifications that bridge from one vertebra to another
tx of ankylosing spondylitis
maintain maximum mobility while decreasing pain and inflammation, local corticosteroid injections, once pain and stiffness are gone exercising is essential, spinal osteotomy and total joint replacement are most frequent procedures
nursing management of ankylosing spondylitis
ROM should include chest expansion (breathing exercises), no smoking, firm mattress and sleep on back with flat pillow avoiding flexion, swimming, racquet games
psoriatic arthritis
progressive inflammatory disease that can involve primary small joints of hands and feet, can involve asymmetric extremities resembling OA, can involve symmetric extremities resembling RA, can involve sacroiliac joints and spine
diagnostics of psoriatic arthritis
x ray looks similiar to erosion in RA, widened joint spaces, elevated ESR, mild anemia, elevated blood uric acid (gout must be excluded)
tx of psoriatic arthritis
splinting, joint protection, physical therapy, DMARDS such as methotrexate
reactive arthritis
occurs more commonly in young men, urethritis, conjuncitvitis, and mucocutaneous lesions included, etiology unknown but associated with GI infections
tx for reactive arthritis
prognonsis is favorable, pt recovers in 2-16 weeks, Vibramycin 100 mg BID
diagnostic for reactive arthritis
up to 50% of people have a recurring disease, x ray in chronic conditions resemble ankylosing spondylitis
septic arthritis
invasion of joint cavity with microorganisms resulting in hematogenous seeding of joint, can be caused by gonorrhea, large joints frequently involved
