Bone connector system
First Claim
1. A bone connector system which comprises first and second connector members, at least one of said connector members carrying an external bone screw thread to permit securance within a bone;
- one of said connector members defining a boss having an outer end, longitudinal slots extending through the boss adjacent said outer end, and a plurality of loops of an external helical screw thread adjacent to said boss outer end, the other of said connector members defining a bore having an internal helical screw thread proportioned to engage said external screw thread when the connectors are brought together.

Abstract
A bone connector system comprises first and second connector members. At least one and preferably both of the connector members carries an external bone screw thread to permit securance within a bone. One of the connector members defines a sleeve having an outer end with longitudinal slots extending through the outer end, and a plurality of loops of an external screw thread positioned adjacent to the outer end. The other of the connector members defines a bore having a multiple loop, internal screw thread proportioned to engage the external thread when the connectors are brought together. Either or both of said connector members may define guidewire lumens.

12. A bone connector system which comprises first and second connector members, said connector members each carrying an external bone screw thread to permit securance within a bone;
- one of said connector members defining a boss having an outer end, longitudinal slots extending through the boss adjacent to said outer end, to define between them in said boss a plurality of separate, longitudinally extending sections which are somewhat flexible in the radial dimension, and a plurality of loops of an external, helical screw thread defined on said boss adjacent to said boss outer end, the other of said connector members defining a lumen extending completely therethrough, said lumen having a wall which defines a multiple-loop internal helical screw thread proportioned to engage said external screw thread when the connectors are brought together, to respectively permit securance of said first and second connectors within different bones.

15. The method of connecting together bones, which comprises:
-
inserting first and second connector members respectively into first and second bones;
inserting a portion of said first connector member into a bore of the other of said connector members, said portion of the first connector member having radial resilience and a plurality of loops of an external helical screw thread, and the second connector member having an internal helical screw thread proportioned to engage said external screw thread as the connectors are brought together, the advancement of said first connector member into the second connector member being substantially without relative rotation, whereby the internal and external helical screw threads advance across each other with resilient radial movement of the first connector member thread until the respective internal and external helical screw threads mate together in helical, retaining relationship at a desired position. - View Dependent Claims (16, 17, 18, 22)
