27
How does skeletal traction work?
applied direclty to the skeletal structure, pin, wire, or tongs inserted into or through the diameter of the bone distal to the fracture
28

bone realignment, lower portion of leg is supported in cast boot or sling
29
How does 90-90 traction work?
Steinmann pin or Kirschner wire in distal fragment of femur, results in 90 degree angle at both the hip and knee
30
What is halo traction useful for?
allows for greater mobility of the body while avoiding cervical spinal motion in displaced or fractured vertebrae
31
How does halo traction work?
steel halo is attached by four screws inserted into outer skull, rigid bars connect halo to a vest
*scheduled neuro assessments
32
What should you assess for with all forms of traction?
