Abstract
The present invention provides a method of forming pilot apertures for surgical screws. The method provides at least three points of contact to the screw shank to provide reliable positioning and retention of the bone screw. The method also provides slots or areas for insertion and retention of bone growth promoting materials which further secure the bone screw over time. The method is useful for patients of all ages, and may be particularly useful for patients that have osteoporosis or patients that are very active by providing additional securement of the bone screw to the underlying bone.
