Abstract
A bone connector system includes first and second connector members, at least one and preferably both, of which carries an external bone screw thread to permit securance within a bone. One of the connector members defines a boss having an outer end with at least one slot therein to form flexible fingers, the boss having flanges which may be formed by an external screw thread adjacent to the outer end, and an external hexagonal engagement surface spaced from the outer end. The other of the connector members defines a bore having grooves which may formed by an internal screw thread proportioned to engage the flanges on the boss, and a hexagonal engagement portion proportioned to mateably receive and engage the hexagonal engagement surface when the connectors are brought together. Each of the flanges and grooves may have first and second flanks respectively disposed at relatively small and relatively large acute angles to the longitudinal axis of the system. Either or both of the connector members may define guidewire lumens.
