Abstract
A bone fastener comprises a first member that defines an implant cavity. A part is disposed with the first member. A retainer is connected with the part and the first member, and includes an expandable orientation and a non-expandable orientation. A second member is connectable to the retainer and configured to penetrate tissue. Implants, systems, instruments and methods are disclosed.
Claims20
A bone fastener comprising:
- a first member defining an implant cavity and having a threaded inner surface;
- a part disposed with the first member;
- a retainer connected with the part and the first member, and including a threaded outer surface configured for engagement with the threaded inner surface of the first member to move the retainer between an expandable orientation and a non-expandable orientation;
- and
- a second member connectable to the retainer and configured to penetrate tissue,
- wherein the first member defines a groove configured for disposal of a band, and
- wherein the retainer is engageable with the part and the first member in the expandable orientation such that the retainer engages the band to provisionally connect the retainer with the first member and in the non-expandable orientation such that the retainer is fixed with the first member.

A bone fastener comprising:
- an implant receiver;
- a crown disposed with the implant receiver;
- a collet connected with the crown and including a threaded outer surface configured for engagement with a threaded inner surface of the implant receiver to translate the collet relative to the implant receiver between an open position and a closed position;
- and
- a screw shaft engageable with the collet and configured to penetrate tissue,
- wherein the implant receiver defines a groove configured for disposal of a band, and
- wherein the collet is engageable with the crown and the implant receiver in the open position such that the collet engages the band to provisionally connect the collet with the implant receiver and in the closed position such that the collet is fixed with the implant receiver.
4 more elements
A bone fastener comprising:
- an implant receiver;
- a crown disposed with the implant receiver, the crown including an inner surface that mates with a surgical instrument and outer flanges;
- a collet comprising notches engaged with the flanges to connect the crown and the collet such that the crown drives and rotates the collet between an expandable orientation and a non-expandable orientation, the collet comprising a threaded outer surface configured for engagement with a threaded inner surface of the implant receiver to translate the collet relative to the implant receiver between the expandable orientation and the non-expandable orientation;
- and
- a screw shaft connectable to the collet and configured to penetrate tissue,
- wherein the implant receiver defines a groove configured for disposal of a band, and
- wherein the collet is engageable with the crown and the implant receiver in the expandable orientation such that the collet engages the band to provisionally connect the collet with the first member.
