Ortho Flashcards
MAIN FUNCTION: (VM is BSS)
Support
Protection of vital organs
Movement
Blood cell production
Mineral storage
bones
Provide supporting framework to body and protect underlying organs and tissues
bones participate in
red and white blood cell production
Serve as a site for storage of inorganic minerals (Ca++,
PO4-) and contain organic
material (collagen)
bones are dynamic or not dynamic?
Dynamic tissue (osteoblasts, osteoclasts)
ligaments (bone gets a lig up from bone)
Connect bones to bones
More elastic than tendons
tendons
Attach muscles to bones
both ligaments and tendons have (blood won’t touch ligs and tendons)
poor blood supply which delays healing
fascia
Layers of connective tissue with intermeshed fibers
bursae (what type of tissue and fluid?)
Small sacs of connective tissue lined with connective tissue containing viscous synovial fluid
age related - loss of bone density due to
increase resorption and decreased formation leading to osteopenia (loss of bone mineral density) and osteoporosis, kyphosis
age related - loss of water from vertebral discs =
loss height
age related - falls
increase likelihood of fractures d/t to loss of bone mass
age related - Increase risk for cartilage
erosion-direct contact between bone ends-osteoarthritis
age related - Decreased muscle mass and strength…how much loss?
almost 30% lost by age 70-leads to decreased ability to release glycogen during stress and decreased BMR
inspection - start with what? (start with the general)
Always start with your initial contact with the patient
Look for symmetry, general body built
palpation
If injury is the presenting problem, proceed with caution
Palpation of soft tissue and joints allows for assessment of skin temperature, swelling, tenderness and crepitation
movement
Observe/ Evaluate ROM
5/5
Normal strength (moves against full resistance)
4/5 (4 is a moderate number)
Moderate strength (moves against some resistance)
3/5
Person can raise hand off table without any resistance applied
2/5
Eg. Person able to slide hand across table but not lift it
1/5
Flicker
0/5
paralysis
sprains and strains
Usually associated with abnormal stretching or twisting
sprain (I sprained my lig)
injury to the ligaments surrounding a joint
Sprains classified according to the amount of ligament fibers torn: 1st, 2nd and 3rd degree (sprains on 1st, 2nd and 3rd base)
First degree: tears of only few fibers
Second degree: partial disruption of the involved tissue with more swelling and tenderness
Third degree: complete tearing of the ligament
STRAIN (I’m straining my muscles)
STRAIN: stretching of a muscle and its fascial sheath
strain clinical manifestation (straining my muscle w/ pain and edema)
Clinical Manifestation include:
Pain, edema, decreased function and bruising
strains and sprains what to do - rice me (and how high to elevate?)
RICE
Rest
Ice
Compression
Elevation above heart level
Analgesia
NSAIDS=decrease prostaglandins that contribute to inflammation and pain; increase risk for GI bleeding in older adults or if in excessive quantity
Opioids if severe
dislocation - what can happen? Worst case
Dislocation:
Needs to be attended promptly
The longer the timeframe before Reduction, the greater the possibility of developing Avascular Necrosis
dislocation nursing care
NURSING CARE:
Pain management
Support/protect the injured part
fractures
Disruption or break in continuity of structure of bone
Majority of fractures from traumatic injuries
Some fractures secondary to disease process
Cancer or osteoporosis
fractures clinical manifestations
Edema and swelling
Localized pain and point tenderness
Decreased function
Muscle spasms
Inability to bear weight or use
Guarding against movement
May or may not have deformity
Ecchymosis and crepitation
Immobilize affected limb if you suspect fracture!!!!
fractures - edema and swelling result from..and can cause what?
disruption of soft tissue or bleeding into the surrounding tissue.
If it occurs in a closed space, it can occlude circulation and damage nerves - May lead to COMPARTMENT SYNDROME
fracture - Compartment Syndrome
Compartment Syndrome:
An elevation of pressure within a closed fascial compartment
Can be caused by hemorrhage and or edema within a closed space or by external compression or arterial occlusion
fracture clinical manifestation (fracture door)
- Pain and tenderness
- Deformity
- Ecchymosis
- Crepitation
fracture objective behavior
Objective Data
Apprehension
Guarding
Point tenderness
Skin lacerations, color changes
Hematoma, edema
Restricted or lost function
Deformities; abnormal angulation
Shortening, rotation, or crepitation (crackling noise)
Imaging findings
fracture neurovascular assessment - (temp, cap refill, pulse, blood)
Peripheral vascular
Color and temperature-⬇temp?
Capillary refill-?prolonged
Pulses- ↓ or absent pulse
Edema, hematoma ( pool of mostly clotted blood)
factors influencing healing (site) and which takes longest to heal?
Displacement and site of fracture (fx)
Type of fx: Open and comminuted fractures take longest
Blood supply to area
Immobilization
Internal fixation devices
Infection or poor nutrition
Age
Smoking
fracture - Closed reduction (you can reduce it yourself) and ex of what type of fractures
Closed reduction
Correction or Setting of a fractured bone without surgery
Ex: hip or shoulder
fracture - open reduction
Open reduction: ORIF (Open reduction and internal fixation)
Surgical incision
Internal fixation-plates, pins and screws, intramedullary nail
Risk for infection
