A second member includes a head and a shaft configured to penetrate tissue. The head includes at least one mating element engageable with the at least one mating element of the first member and a part. A third member includes an inner surface engageable with the part such that the members comprise a bone fastener having a selected movement. Systems, instruments and methods are disclosed. ## Claims ### Claim 1 A spinal implant comprising: a first member including an inner surface defining an implant cavity and at least one mating element; a second member including a head and a shaft configured to penetrate tissue, the head including at least one mating element engageable with the at least one mating element of the first member and a part; and a third member including an inner surface engageable with the part such that the members comprise a bone fastener having a selected movement. ### Claim 2 (depends on 1) A spinal implant as recited in claim 1, wherein the inner surface of the third member defines an opening that defines the selected movement. ### Claim 3 (depends on 1) A spinal implant as recited in claim 1, wherein the inner surface of the third member defines an elongated slot that defines the selected movement. ### Claim 4 (depends on 1) A spinal implant as recited in claim 1, wherein the part includes a protrusion extending from an outer surface of the head. ### Claim 5 (depends on 1) A spinal implant as recited in claim 1, wherein the part includes an even, spherical outer surface disposed with an upper portion of the head. ### Claim 6 (depends on 1) A spinal implant as recited in claim 1, wherein the selected movement includes the second member being moveable about a plurality of axes relative to the first member. ### Claim 7 (depends on 1) A spinal implant as recited in claim 1, wherein the selected movement includes the second member being moveable about a single axis relative to the first member. ### Claim 8 (depends on 1) A spinal implant as recited in claim 1, wherein the selected movement includes the second member being fixed relative to the first member. ### Claim 9 (depends on 1) A spinal implant as recited in claim 1, wherein the at least one mating element of the first member includes a lateral protrusion. ### Claim 10 (depends on 1) A spinal implant as recited in claim 1, wherein the at least one mating element of the first member includes a pair of lateral protrusions aligned with a transverse axis of the first member. ### Claim 11 (depends on 1) A spinal implant as recited in claim 1, wherein the at least one mating element of the second member includes a pair of longitudinal grooves spaced about an outer surface of the second member. ### Claim 12 (depends on 1) A spinal implant as recited in claim 1, further comprising an insert disposable with the third member and engageable with the part to define an alternate selected movement of the bone fastener. ### Claim 13 (depends on 1) A spinal implant as recited in claim 1, wherein the insert includes a flange engageable with the third member for fixation therebetween. ### Claim 14 (depends on 1) A spinal implant as recited in claim 1, wherein the third member defines a groove configured for capture of a spinal rod in a selected plane of a body. ### Claim 15 (depends on 1) A spinal implant as recited in claim 1, wherein the inner surface of the first member defines a groove configured for disposal of a circumferential ring that defines a gap. ### Claim 16 A spinal implant comprising: a receiver including an inner surface having at least one lateral protrusion; a screw including a head and a threaded shaft, the head including at least one longitudinal groove engageable with the at least one lateral protrusion and a part; and a crown including an inner surface engageable with the part such that the receiver and the screw comprise a bone fastener having a selected movement. ### Claim 17 A spinal implant system comprising: a first member including an inner surface defining an implant cavity and at least one mating element; a second member including a head and a shaft configured to penetrate tissue, the head including at least one mating element engageable with the at least one mating element of the first member and a part; and a plurality of alternate third members, each third member including an inner surface engageable with the part such that the third member is interchangeable with the members to comprise a bone fastener having a selected movement. ### Claim 18 (depends on 17) A spinal implant system as recited in claim 17, wherein the selected movement includes the second member being moveable about a plurality of axes relative to the first member. ### Claim 19 (depends on 17) A spinal implant system as recited in claim 17, wherein the selected movement includes the second member being moveable about a single axis relative to the first member. ### Claim 20 (depends on 17) A spinal implant system as recited in claim 17, wherein the selected movement includes the second member being fixed relative to the first member.
