Abstract
A bone fastener comprises a first member defining an implant cavity and a plurality of adjacent grooves. A first band is configured for disposal within the grooves. A second band is configured for disposal within the grooves. A second member is configured to penetrate tissue and includes a head engageable with the first band to provisionally connect the members. The second band is moveable for disposal adjacent the first band to fix connection of the members. Implants, systems, instruments and methods are disclosed.
Claims21
1-20. (canceled)
A spinal implant comprising:
- a spherical head;
- and
- a head assembly comprising:
- a first retaining ring;
- a second ring;
- a receiver having spaced apart arms that define an implant cavity, the implant cavity configured to receive a spinal rod, the receiver having a bottom opening in communication with an internal surface, the bottom opening configured to receive the spherical head, the internal surface defining a first groove, a second groove spaced apart from the first groove, and a circumferential channel located in between the first groove and the second groove, wherein the first groove is configured to receive the first ring and the second groove is configured to receive the second ring.

- and
- a head assembly comprising:
- a first retaining ring;
- a second ring;
- a receiver having spaced apart arms that define an implant cavity, the implant cavity configured to receive a spinal rod, the receiver having a bottom opening in communication with an internal surface, the bottom opening configured to receive the spherical head, the internal surface defining a first groove, a second groove spaced apart from the first groove, and a circumferential channel located in between the first groove and the second groove, wherein the first groove is configured to receive the first ring and the second groove is configured to receive the second ring, the second groove including a projection that is disposed in a recess of the second ring when the second ring is positioned in the second groove;
- and
- a crown engageable with the second ring to dispose the second ring adjacent the first ring to fix connection of the spherical head with the receiver,
- wherein the crown portion is configured to fit within the internal surface, the crown having a circumferential wall, a first upper surface, and an upper curved portion configured for engagement with the spinal rod.
