What is multiplane external fixation?
The concept is simple, yet effective. Metal pins and wires are attached to certain areas of the bone away from the actual fracture. The other ends of pins are then attached to a metal rod that prevents the bones from moving in any direction. Once the fracture has sufficiently healed, the pins and rods can be removed.
What is radial preloading?
Preloading the implant-bone interface is believed to retard this process. Radial preload, in particular, may be useful, as it allows loading in more than one direction. High degrees of radial preload, exceeding the elastic limit of cortical bone, may be produced around pin holes by a small misfit.
How do I install a Steinmann pin?
A Steinmann pin or K-wire, mounted in the T-handle or wire driver, is inserted manually at a point about 2-3 fingers above the superior pole of the patella. As the pin is felt to penetrate the far cortex, check that the exit will coincide with the area of local anesthetic infiltration.
