Abstract

A system and method are for bone fixation. A radially expandable sleeve is inserted over an elongated shaft of a bone screw. The bone screw and radially expandable sleeve are inserted into a transverse opening extending through a bone fixation device positioned in a bone until the radially expandable sleeve is fully housed within the transverse opening. The bone screw is further screwed into the bone relative to the radially expandable sleeve to cause expansion of the radially expandable sleeve within the bone fixation device, thereby locking the sleeve to the bone fixation device.
