Abstract
A method of assembly for a bone fastener is provided. The method includes the steps of: engaging a retainer with an implant receiver in a relatively fixed position; translating the retainer relative to the implant receiver to an expandable orientation; and manually engaging a screw shaft with the retainer to connect the implant receiver with the screw shaft. Implants, systems and instruments are disclosed.
Claims20
A method of assembly for a bone fastener, the method comprising the steps of:
- connecting a collet with a crown and disposing the collet with an inner surface of an implant receiver such that the collet is threaded with the inner surface;
- disposing the collet in a relatively fixed position with the implant receiver and a non-expandable orientation;
- translating the collet relative to the implant receiver to an expandable orientation;
- and
- manually engaging a screw shaft with the collet to connect the implant receiver with the screw shaft.
A method of assembly for a bone fastener, the method comprising the steps of:
- releasably locking a collet with an inner surface of an implant receiver in a closed position, the collet being threaded with the inner surface;
- translating the collet relative to the implant receiver to an open position;
- and
- manually engaging a screw shaft with the collet to connect the implant receiver with the screw shaft.
A method of assembly for a bone fastener, the method comprising the steps of:
- connecting a collet with a crown and disposing the collet with an inner surface of an implant receiver such that the collet is threaded with the inner surface, the collet comprising a circumferential sleeve, the sleeve defining spaced apart slots, the slots each extending through a wall of the sleeve;
- disposing the collet in a relatively fixed position with the implant receiver and a non-expandable orientation;
- translating the collet relative to the implant receiver to an expandable orientation, the crown including spaced apart circumferential outer flanges, the outer flanges engaging the collet as the collet translates relative to the implant receiver;
- and
- manually engaging a screw shaft with the collet to connect the implant receiver with the screw shaft.
