## Abstract

A bone fastener includes a receiver defining an implant cavity and having an inner surface defining a slot. A band is disposable within the slot. A spacer disposable within the slot. A crown is rotatable relative to the receiver to translate the spacer relative to the inner surface such that the spacer orients the band in a capture orientation with the shaft. A screw shaft connectable with the receiver by the band and configured to penetrate tissue. Implants, systems, instruments and methods are disclosed.

## Claims

### Claim 1

A bone fastener comprising:
a receiver defining an implant cavity and including an inner surface defining a slot;
a band disposable within the slot;
a spacer disposable within the slot;
a crown being rotatable relative to the receiver to translate the spacer distally relative to the inner surface such that the spacer orients the band in a capture orientation; and
a screw shaft connectable with the receiver by the band and configured to penetrate tissue,
wherein the spacer is disposable in a distalmost position with the slot and engageable with the band in the capture orientation to permanently lock the receiver with the shaft.

### Claim 2 (depends on 1)

A bone fastener as recited in claim 1, wherein the spacer is engageable with the band to dispose the band in a contracted, capture orientation to fix the receiver with the shaft.

### Claim 3 (depends on 1)

A bone fastener as recited in claim 1, wherein the spacer is disposable in the distalmost position to provide tactile feedback.

### Claim 4 (depends on 1)

A bone fastener as recited in claim 1, wherein the band is disposable between an expanded orientation and a contracted, capture orientation.

### Claim 5 (depends on 1)

A bone fastener as recited in claim 1, wherein the band includes a circumferential ring defining a gap.

### Claim 6 (depends on 1)

A bone fastener as recited in claim 1, wherein the spacer is fixedly connected to or formed integrally with the crown.

### Claim 7 (depends on 1)

A bone fastener as recited in claim 1, wherein the spacer includes an outer surface being slidably engageable with the inner surface to facilitate axial translation of the spacer relative to the slot.

### Claim 8 (depends on 1)

A bone fastener as recited in claim 1, wherein the spacer includes an inner circumferential flange engageable with a distal end surface of the crown.

### Claim 9 (depends on 1)

A bone fastener as recited in claim 1, wherein the spacer includes a ramp surface engageable with the band.

### Claim 10 (depends on 1)

A bone fastener as recited in claim 1, wherein the spacer includes an inner circumferential ramp surface engageable with an outer surface of the band to dispose the band in a contracted, capture orientation.

### Claim 11 (depends on 1)

A bone fastener as recited in claim 1, wherein the rotatable crown includes a cam surface engageable with the receiver to axially translate the crown relative to the receiver.

### Claim 12 (depends on 11)

A bone fastener as recited in claim 11, wherein the cam surface includes a circumferential ridge disposed about at least a portion of the crown.

### Claim 13 (depends on 1)

A bone fastener as recited in claim 1, wherein the shaft is manually engageable with the receiver for non-instrumented assembly.

### Claim 14

A bone fastener comprising:
a receiver defining an implant cavity and including an inner surface defining a slot;
a band disposable within the slot;
a spacer disposable within the slot, the spacer including a ramp surface engageable with the band;
a crown being rotatable relative to the receiver to translate the spacer distally relative to the inner surface such that the spacer orients the band in a capture orientation; and
a screw shaft connectable with the receiver by the band and configured to penetrate tissue.

### Claim 15 (depends on 14)

A bone fastener as recited in claim 14, wherein the ramp surface is engageable with an outer surface of the band to dispose the band in a contracted, capture orientation.

### Claim 16 (depends on 14)

A bone fastener as recited in claim 14, wherein the spacer is engageable with the band to dispose the band in a contracted, capture orientation to fix the receiver with the shaft.

### Claim 17 (depends on 14)

A bone fastener as recited in claim 14, wherein the band is disposable between an expanded orientation and a contracted, capture orientation.

### Claim 18

A bone fastener comprising:
a receiver defining an implant cavity and including an inner surface defining a slot;
a band disposable within the slot;
a spacer disposable within the slot;
a crown being rotatable relative to the receiver to translate the spacer distally relative to the inner surface such that the spacer orients the band in a capture orientation, the crown including a cam surface engageable with the receiver to axially translate the crown relative to the receiver; and
a screw shaft connectable with the receiver by the band and configured to penetrate tissue.

### Claim 19 (depends on 18)

A bone fastener as recited in claim 18, wherein the cam surface includes a circumferential ridge disposed about at least a portion of the crown.

### Claim 20 (depends on 18)

A bone fastener as recited in claim 18, wherein the spacer is engageable with the band to dispose the band in a contracted, capture orientation to fix the receiver with the shaft.

### Claim 21 (depends on 18)

A bone fastener as recited in claim 18, wherein the band is disposable between an expanded orientation and a contracted, capture orientation.
