closed reduction vs open reduction for fracture
closed- nonsurgical
open-surgical. infection risk. early amputation encourages
29
traction
pulling force to attain alignment- counter-traction pulls in opposite direction
these weights need to dangle- not touch ground
patient will always be laying supine when doing this
30
bucks traction (skin)
short term use (48-72hr)

not surgical- applied to skin by boot
make sure to assess the skin under the cover
