Abstract
A surgical screw that includes a body portion that facilitates bone in-growth from a bone in which the screw is mounted so as to stabilize the screw in the bone. The body portion can have various configurations for facilitating bone in-growth, such as indentations, a roughened surface, such as by acid etching or abrasive media blasting, specialized coatings, such as hydroxyapetite, sintered beads, machined channels, etc. Because the body portion of the screw facilitates bone growth, the screw will be more firmly mounted to the bone so as to have a greater integrity in response to movement of the bone. The type of surgical screw can be any surgical screw that will benefit from being better anchored in bone, such as pedicle screws, long bone screws, cervical fusion screws, tendon anchoring screws, etc.
