Abstract
A bone fastener includes a first member having an inner surface defining an implant cavity and at least one mating element. A second member is disposed with the first member and is configured to penetrate tissue. A part is moveable relative to the second member and configured for disposal of an implant. The at least one mating element is engageable such that the first member is moveable relative to the second member to dispose the implant at a desired orientation relative to the second member. Implants, systems, constructs, instruments and methods are disclosed.
Claims20
A bone fastener comprising:
- a first member including an inner surface defining an implant cavity and a cavity, the first member including at least one mating element, the first member comprising a pair of spaced apart arms, wherein the at least one mating element is a groove that extends through one of the arms, the other arm being free of any grooves;
- a second member disposed with the first member and configured to penetrate tissue;
- a ring positioned in the cavity, the second member extending through the ring such that the second member is prevented from translating axially relative to the first member in one direction;
- and
- a part moveable relative to the second member and configured for disposal of an implant,
- wherein the groove is engageable such that the first member is moveable relative to the second member to dispose the implant at a desired orientation relative to the second member.
A spinal implant system comprising:
- a receiver including an inner surface defining an implant cavity and a cavity, the receiver including a pair of spaced apart arms and a groove extending through one of the arms, the other arm being free of any grooves;
- a bone anchor disposed with the receiver;
- a ring positioned in the cavity, the bone anchor extending through the ring such that the bone anchor is prevented from translating axially relative to the receiver in one direction;
- a crown moveable relative to the bone anchor and configured for disposal of an implant;
- and
- a tool disposable within the groove, the tool being configured to pivot the receiver relative to the bone anchor to dispose the implant at a desired orientation relative to the bone anchor.
A spinal implant system comprising:
- a plurality of alternate implant receivers including at least one implant receiver comprising an inner surface defining an implant cavity and a cavity, the at least one implant receiver comprising at least one mating element, the at least one implant receiver comprising a pair of spaced apart arms, wherein the at least one mating element is a groove that extends through one of the arms, the other arm being free of any grooves;
- a bone anchor including a head engageable with an implant receiver such that the bone anchor is compatible with each of the plurality of implant receivers, the head including a pair of flats that are positioned opposite one another, the flats directly engaging planar portions of the inner surface such that the bone anchor is rotatable relative to the at least one implant receive in only one plane;
- a snap ring positioned in the cavity, the bone anchor extending through the snap ring such that the bone anchor is prevented from translating axially relative to the at least one implant receiver in one direction;
- a crown moveable relative to the bone anchor and configured for disposal of an implant;
- and
- a tool disposable within the groove,
- wherein the at least one implant receiver is selected for connection with the bone anchor to comprise a bone fastener and the tool is configured for disposal in the groove to pivot the at least one implant receiver relative to the bone anchor to dispose the implant at a desired orientation relative to the bone anchor.
