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.
A surgical screw comprising a head portion and a body portion, said body portion including a textured surface other than screw threads that facilitates bone in-growth to the screw so that the screw is more rigidly mounted to bone.
A pedicle screw for spinal fusion surgery, said screw comprising a head portion and a body portion, said body portion including a plurality of openings that facilitate bone growth to the screw so that the screw is more rigidly mounted to the vertebra.
A surgical screw comprising a head portion and a body portion, said body portion including an outer layer of hydroxyapetite that facilitates bone in-growth to the screw so that the screw is more rigidly mounted to bone.
