Abstract
A radial impacting technique involves using a set of progressively larger radial impactors to pack a medullary canal in a radial direction toward the cortex. For revision cases, graft material, which may be either synthetic or bone graft material, is added into the medullary canal after the previously installed implant has been removed. Packing the medullary canal in the radial direction, as opposed to the conventional approach of packing in a distal direction, provides superior results. The radial impactors are preferably cannulated and may also have holes to assist in the removal of fluids from within the medullary canal. The profile impactors may be either cannulated or non-cannulated and prepare the medullary canal for receipt of the implant.
