Orthopedic screw insert

An insert for receiving a bone screw comprising:

• a) 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;
• and
• b) a plurality of elongate slots formed in the wall of the sleeve for promoting flexure of the insert and including:
• i) at least one pair of diametrically opposed distal slots extending from the distal end of the sleeve;
• and
• ii) at least one pair of diametrically opposed proximal slots extending from the proximal end of the sleeve, wherein the inner peripheral surface of the sleeve includes internal threads configured for threaded engagement with threads of an orthopedic screw, wherein a distal portion of the inner peripheral surface is free of internal threads to provide an expansion profile wherein the distal end of the sleeve is expanded more than a portion of the sleeve between the proximal and distal ends when a bone screw is received in the sleeve for engaging a distal section of the outer peripheral surface with cancellous bone.
