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.
