Week 7 - Bone Fractures Flashcards
what is a fracture
- disruption or break in the continuity of the structure of bone
what 4 ways can fractures be classified and what do they mean
- open = skin is broken, bone exposed, soft tissue injury
- closed = skin not ruptures, skin intact
- complete = break completely thru the bone
- incomplete = occurs partly across the bone, bone still in one piece
what are symptoms of fractures (8)
- immediate localized pain
- decreased function
- inability to bear weight
- obvious bone deformity may be present
- extremity immobilized in position it was found
- swelling
- bruising
- crepitation
what is used to diagnose a fracture (3)
- xray
- ct
- MRI
what are the overall goals of fracture treatment (3)
- anatomical realignment of bone fragments = reduction
- immobilization to maintain realignment
- restoration of normal or near normal function of the injured extremity
what are the 2 types of fracture reduction
- open
- closed
what is a closed reduction
- nonsurgical, manual realignment of bone fragments to their previous anatomical position
- often involves traction & countertraction
- usually performed under local or general anasthesia
what is traction
- process of slowly and gently pulling on a fractured or dislocated body part
- application of a pulling force on a fractured extremitity to attain realignment
after closed reduction, what is done
- traction, casting, external fixation, splints, or braces are used to immbolize the injury to maintain alignment until healing occurs
what are 2 types of traction
- skin
- skeletal
what is skin traction
- traction used for short term treatment (48-72 hr) until skeletal traction or surgery is possible
- includes tape, boots, or splints directly applied to the skin
what is skeletal traction
- traction generally in place for longer periods of time
- provides a long term pull that keeps the injured bone and joints aligned
- involves insertion of a pin or wire into the bone
what is a disadvantage associated w skeletal traction (2)
- risk of infection
- prolonged immobility
what is open reduction
- correction of bone alignment thru a surgical incision
- often includes internal fixation of the bone using wires, screws, plates, pins, rods, or nails
what are the disadvantages of open reduction
- risk of infection
- use of anasthesia
what must be done after open reduction (2)
- early initiation of ROM
- use of machines that provide continuous passive motion to joints
what is the benefit of open reduction with internal fixation
- facilitates early ambulation
= decreased r/o complications r/t prolonged immobility
what is countertraction
- pulls in the opposite direction of traction
for traction to be effective, what is required
- countertraction
how is countertraction supplied
- either by pt’s body weight
- pr weights pulling in the opposite direction and may be augmented by elevated the bed
what is imp r/t traction (3)
- must be maintained continuously
- keep weight off the floor
- keep weight moving freely thru pulleys
what is the benefit of casts
- allows the pt to perform many normal ADLs while still providing sufficient immobilization
what are the 2 types of casts
- plaster
- fiberglass
describe how a plaster cast is applied (4)
- pad bony prominences
- plaster immersed in water then wrapped around affected joint
- plaster sets within 15 min
- 24 hr dry period
