Bones: Three Layers
Bone surroundings
Muscles:
Sprains
Strains
- Often due to excessive stretching or overexertion
S&S of sprains and strains
Treatment of Sprains/Strains
Coban
Bandage with more stretchiness and sticks to itself- (start at bottom and work your way up)
Fractures (Causes)
Pathophysiology of Fractures
S&S of fractures
-Edema
-Pain
-Muscle spasms
-Deformity
-Ecchymosis
-Loss of function
-Crepitation (feels like bubble wrap)
-Numbness
-Hypovolemic shock
(S&S are mostly the same for sprain, strain, & fracture so you can only tell by an x-ray)
Diagnostic Tests
X-rays
CAT scan- no need unless its in your back
MRI- no need unless its in your back
Bone Scan- nuclear med scan; injected with nuclear stuff and start looking for uptake in x-ray
Stages of Healing
Complications with fractures: Delayed Union
healing does not occur within normal expected time frame
Complications with fractures: Non-union
Fracture never heals; two ends of bone do not fuse together
Complications with fractures: Infection
Can be seen in open fractures or any fracture with surgical intervention; can lead to delayed union or non-union
Complications with fractures: Avascular Necrosis
An interruption in blood supply to bony tissue, which results in death of bone (most common with steroid use
S&S; pain and decreased sensation
Complications with fractures: Compartment syndrome
S&S of compartment syndrome
Treatment of compartment syndrome
Fix cause; stop bleeding or remove tight cast
-Fasiotomy: make incision into fascia to open up compartment space & decrease pressure
(can lead to tissue death and amputation)
-If you have any idea that it’s compartment syndrome, put pt. on NPO to get ready for OR
Complications with fractures: Venous Thrombosis
Complications with fractures: Fat embolism
Fat Embolism (where it occurs)
Fat Embolism: treatment
Fat Embolism: S&S
Confusion, ^RR, crackles (fluid in lungs), Petechia (really small pinpoint rash- not raised, purplish red)
