Comparative application of traction
Application of traction breaks the spasm and eliminates much of the pain. It also causes
alignment of the bone fragments and subsequent increased tissue pressure. This reduces and
controls bleeding and shock, and prevents further nerve, vascular and tissue damage. It is clear
that properly applied traction and immobilization of a fractured Femur helps control shock
and reduces mortality.
The traction needed to break the spasm of muscles associated with a fractured Femur is a product
of the traction force and the length of time it is applied. A very large traction force only needs
to be applied a short while for muscle fatigue and relaxation of the spasm to occur. Large traction
forces, generally in excess of 30 to 50 pounds can in some cases control spasm in a few
seconds. However, there is a risk with this mode of traction. It may result in nerve, vascular, muscle
and soft tissue injury, as well as over-extension of bone fragments. Gentle traction, “… the amount
of pull required to accomplish this (traction) will vary but rarely exceed 15 pounds. This is gentle
traction, and the least amount of force necessary is the amount that should be employed”
