Abstract
An insert for receiving a bone screw includes an elongate sleeve having opposed proximal and distal ends and a wall defined by an outer peripheral surface configured for engaging bone and an inner peripheral surface configured for receiving a bone screw extended therethrough. At least one elongate slot is formed in the wall of the sleeve for promoting flexure of the insert. A tool for affixing an orthopedic screw insert within bone tissue includes a socket portion configured and adapted to engage a proximal section of an outer peripheral surface of an orthopedic screw insert. A driver extends distally from the socket portion. The driver is configured and adapted to engage a section of an inner peripheral surface of the orthopedic screw insert distal from the socket portion.
