4 steps to bone healing with Fx's
- Bone injury: hematoma
- Fibrocartilaginous Callus Formation
- Bony Callus formation
- Remoldeling
-
Fibrocartilaginous Callus Formation
- starts w/n 48 hours
- granulation replaces hematoma
- osteoblasts build web of collagen
-
Bony Callus formation
- starts in 3-4 weeks
- new bone
- osteoclasts invade: reabsorb excess callus as it is replaced by mature bone
-
remodeling stage
- 2-4 months for full repair
- plates/bars are laid down
- repaired along lines of stress
-
factors in bone healing
- Ca
- Vit D
- Alkaline Phosphatase= bld work for bone disease shows Inc Alk Phosph
- Decrease circulation (diabetes)
- No osteoporosis or infections
-
myelogram
nrsing focus pre- and post-test
Dx test done to look at problems with spinal cord/column
pre= drug allergies to shelfish (dye)
- post=bedrest, HOB elevated
- =fluids
- =site checks Q1hr of the lumbar puncture
-
hallmark sign of CSF leak?
halo on bandage
-
Dislocation
Subluxation
D= loss of articulation of the bone ends in the joint cap
S= partial dislocation where bone ends still partially touch
-
Nursing care (Dx) for joint trauma
1-3
- Risk for injury - Neurovascular compromise
- Acute pain - ice/heat, splint, NSAIDS
- Impaired Physical Mobility
-
Bursitis
Epicondylitis
CTS
repetition injurys
B= inflammation of the bursa
- Epi= inflamm of tendon at point of origin to bone
- = tennis elbow
- CTS= carpal tunnel
- = compression of median nerve and inflamm of synovial sheath
- = Phalen test used to Dx
-
types of fractures:
complete vs incomplete
with vs w/o displacement
simple vs compound
- c= total segment vs partial
- w= unstable vs stable
- s= closed vs open
-
goal of reduction (fx)
- approxiate segments
- restore to nl position
-
goal of immobiliazation
fixation/alignment of segments
-
internal fixation
adv. and disadv.
pins, rods, etc.
- a=fast ambulation
- d=surgery required
ORIF
-
external fix
adv and disadv.
cast, splint
- a= may not need surgery, may allow for more movement
- = external fix (think Penny) may allow for more movement
- d= casts means slow ambulation
- = ext. fix require surgery
-
cast care
1-7
- elevation
- rotation while drying
- pad skin edges
- pain control
- window or bivalve to relieve pressure
- nuerovasc changes (monito 5 p's)
- hotspots and draignage
- cool air to relieve itching
-
skin traction
- short term
- low weight
- immoblize and align
- prevent ms spasms
do not use if they have a fracture
-
Buck Traction
used for a hip fracture prior to surgery to prevent ms spasms
-
skeletal traction
- long term
- infection risk
- more weight
- never remove weights
- provide surgery site care
-
auotgraft
allograft
sites used for donation
auto= from pt
allo= from donor
sites= illiac crest or tibia
These are bone grafting terms
-
delayed union
non-union
malunion
healing complications
d= abnl time but still <6 months
n= no heal w/n 6-9 months
m= growth of frag. of bone in a faulty position
-
Sx and care of osteomyelitis
Sx= high fever and chills, redness to ulceration and drainage
Tx= hygeine and aseptic practices, antibiotics
-
fat embolism occurs when?
w/n a few hours or up to one week
-
fat released
fat breaks into f. acids, attracting platelets
sm vessel occlusion
ischemia
- fat released
- fat breaks into f. acids, attracting platelets
- sm vessel occlusion
- ischemia
-
S & Sx of fat embolism
1-3
- Resp failure: hypoxia
- = tachycardia, tachypnea, fever
LOC changes, seizures
- Petechiae; chest, upper arms, axilla
- **Hallmark sign***
-
care of fat embolism
- recognize s & sx
- O2, ABG's
- corticosteroids for anti-inflamm
-
what and when can cause compartment syndrome?
- poor fitting casts
- edema
- hemorrhage
w/n 1st 48 hours
-
comp. synd
inc. pressure traps nerves and vessels
causes hypoxia, capilarry dilitation, edema, and necrosis
- comp. synd
- inc. pressure traps nerves and vessels
- causes hypoxia, capilarry dilitation, edema, and necrosis
-
Sx of comp. synd.
- severe pain
- cyanosis
- weakness
- parestesia (numbing)
-
Tx of comp synd
- decompress fasciotomy
- antibiotics
- pain management
-
hip fracture location
- proximal 1/3 of femur
- -head, neck, trochanter region
- intercapsular
- vs
- extracapsular
-
intracapsular
- w/n joint
- head or neck of femur
Tx= Arthroplasty
-
extracapsular
- outside the joint
- trochanter region
Tx= ORIF
-
nursing care of hip fracture
- No ADDUCTION
- Turn to UNAFFECTED side
- ambulate w/n 1st 24 hours
- no flexion >90 degrees (raised toilet seat)
-
size and placement of TKR incision
what is cut through?
- 8-12 inches on front of joint
- cut thru quadriceps and tendons
-
What is some priorities for a spinal fracture?
- Cord Decompression - 1
- and Airway stability
-
spinal injuries:
@ or above C-8
@ of below T-1
C-1 - C-3
C3 - C5
- C8= tetraplegia (quad)
- T1= paraplegia
- C1-3= cardio and resp. collapse
- C3-5= resp paralysis
-
Spinal shock: cervical or high thoracic injuries
- cause: massive vasodilation
- flaccid paralysis below injury
- Body temp at room temp
- BP-HypoTN, Pulse-Bradycardia
-
Autonomic dysflexia
- SCI's at or above C-6
- triggered by stimulant that causes abd. discomfort, like a full bladder
- Neurologic Emergency
- BP- Sever HTN, Pulse- Bradycardia
