articulation, or a place where the ends of 2 bones are in proximity and move in realation to each other |
Joint
|
|
|
synovial membrane does what?
|
secretes thick synovial fluid which lubs the joint an allows for opposing surfaces to slide against one another
|
|
|
OA is what?
|
-disorder of the diarthrodial (synovial) joints shoulder, knee
-most common form of joint (articular cartilage) disease in US -slowly progressive -non-inflammatory |
|
|
OA was also called what?
|
Degenerative joint disease
|
|
|
What are the 2 types of OA?
|
-idiopathic (use to be primary)
-secondary (caused by another event) |
|
|
non-mod RF for OA?
|
-age
-sex -genetics -joint instability -inflammation -skeletal deformities |
|
|
mod RF for OA?
|
-obesity
-trauma -mechanical stress -drugs (steroids) |
|
|
OA occurs how?
|
-cartiliage becomes dull, yellowed & granular (softer and less abe to resist wear)
-body attempts to repair, but can't keep up with destruction -central cannal becomes thinner & bony growth occurs at the margins -uneven growth occurs which means the bones aren't flush with each other -bone on bone contact |
|
|
The bony growth in the bone is what?
|
osteophytes
|
|
|
a summary of OA is what?
|
-progressive degeneration of joints
-which causes the formation of bony buildup -and the loss of articular cartilage |
|
|
OA occurs mainly in what bones?
|
-hands
-knees -hips -spine -wt bearing joints |
|
|
What is the predominant symptom?
|
Joint pain
|
|
|
T/F
There is an increase of function due to bone loss? |
False, decrease of function
|
|
|
Stiffness occurs when, and lasts how long?
|
after rest period for about 30 min.
|
|
|
Crepitus is what?
|
grating sensation caused by irregular & loose particles of cartilage in joint
|
|
|
OA occurs in symmetrical joints? (both hands, both knees)
|
- False (RA is symetrical)
- OA is asymmetrical |
|
|
Is there deformity with OA?
|
Yes
|
|
|
Pain associated with OA is what?
|
-INCREASED with joint use
-in advanced disease, pain is @ rest -WEATHER CHANGE pain -localized pain |
|
|
deformities with OA are what?
|
-Heberden's (distalinterphalangeal joint) tips of fingers
- Bouchards ( proximal interphalangeal joint) middle, and base knuckles -knee malalignment (uneven knee due to cartilage loss) |
|
|
Diagnostics of OA include
|
-bone scan
-CT scan -MRI -X-rays (used to confirm disease and monitor progression) -ESR (will be normal unless acute synovitis then min. elevation) -WBC <2000 |
|
|
Care of OA focuses on what?
|
-Pain management
-Maintain/ improve joint function -Prevent disability |
|
|
What is the 5th V/S?
|
Pain
|
|
|
RN interventions
|
-assess
-meds -rest periods (they can't rest to long) -exercise -nut. support (obese) -assistive devices "DME" -heat thearpy -safe environment (no rugs) -saftey (shower bars) -education to disease |
|
|
Non Drug care
|
-rest- joint shoujld be rested during acute episodes
-joint protection (knee guard) -heat/cold therapy -acupuncture, yoga, massage |
|
|
Other than weather change and asymmetrical what other big difference is there between OA and RA?
|
OA is non inflammatory, non joint swelling
|
|
|
So drugs to treat OA are aimed at what?
|
prevention and pain
|
|
|
OA drugs are what?
|
-Acetaminophen (1000 mg Q6hr) not to exceed 4 g
-Capsaicin (topical) -ASA -NSAIDS -COX 2 inhibitor (Celebrex) problem's though -intra-articular injections of cort. steroids -and injection of Hyaluronic acid |
|
|
rules for Hyalgan/Synvisc
intra-articular injections |
-weekly injections
-repeat courses of viscosupplimentation can be preformed after 6 months -pain relief can last for a year |
|
|
What is Viscosupplimentation?
|
it replaces natural lub in the joint (Hyaluronic acid)
|
|
|
What type of exercise should be done for OA?
|
non Wt bearing (puts more stress on those joints)
aerobics, walking, climbing, NOT running, sports |
|
|
Why is the FLACC scaled used?
|
to asscess people in pain who can't speak
|
|
|
Our RNing goals are what?
|
-pain management through pharmacologic and non-pharm.
-maintenance/improvement of joint function -use of joint protection to improve activity -independence in self-care activities |
|
|
Some examples of assistive devices are what?
|
-button hook
-sock arms -high toilet seat |
