## Abstract

Disclosed spinal implants may include a rod extending in a horizontal direction and a first implant receiver having a first passageway extending in the horizontal direction and a first threaded passageway extending in a vertical direction, for example. Additionally, the implant may include a second implant receiver having a second passageway extending in the horizontal direction and a second threaded passageway extending in the vertical direction, for example. The implant may include a first set screw having a size and shape corresponding to a size and shape of the first threaded passageway and a second set screw having a size and shape corresponding to a size and shape of the second threaded passageway, for example. In some embodiments, the rod may extend in the horizontal direction through the first and second passageways and may be constrained from moving in the vertical direction by the first and second passageways, for example.

## Claims

### Claim 1

a first set screw having a first outside thread pattern extending along an outside circumferential surface of the first set screw and having a size and shape corresponding to a size and shape of the first threaded passageway; and
a second set screw having a second outside thread pattern extending along an outside circumferential surface of the second set screw and having a size and shape corresponding to a size and shape of the second threaded passageway,
wherein the rod of the preassembled combination extends in the lateral direction through the first and second rod receiving passageways, includes a first endcap and a second endcap, and is constrained from moving in the longitudinal direction by the first and second rod receiving passageways.

### Claim 2 (depends on 1)

The implant of claim 1, wherein:
the first implant receiver includes a first base portion for coupling to a first bone screw, and
the second implant receiver includes a second base portion for coupling to a second bone screw.

### Claim 3 (depends on 2)

The implant of claim 2, comprising:
a first crown having curved surfaces having a size and shape corresponding to an underside of the rod, the first crown being positioned within the first base portion and above the first bone screw; and
a second crown having curved surfaces having a size and shape corresponding to the underside of the rod, the second crown being positioned within the second base portion and above the first bone screw.

### Claim 4 (depends on 3)

The implant of claim 3, wherein at least one of the first base portion and second base portion is configured for mating with a uni-axial bone screw.

### Claim 5 (depends on 4)

The implant of claim 4, wherein, in a top down view, the rod extends in the lateral direction such that the rod is oriented directly above the first bone screw and second bone screw.

### Claim 6 (depends on 1)

The implant of claim 1, wherein:
a solid first upper surface of the first implant receiver is disposed above the first rod receiving passageway, and
a solid second upper surface of the second implant receiver is disposed above the second rod receiving passageway.

### Claim 7 (depends on 1)

The implant of claim 1, wherein a perimeter of the first rod receiving passageway is enclosed, and a perimeter of the second rod receiving passageway is enclosed.

### Claim 8 (depends on 1)

The implant of claim 1, wherein the preassembled combination comprises at least the first implant receiver, second implant receiver, first set screw, second set screw, and rod such that the first set screw is disposed in the first threaded passageway and the second set screw is disposed in the second threaded passageway.

### Claim 9 (depends on 1)

The implant of claim 1, wherein a size of the first endcap is greater than a size of the first rod receiving passageway and a size of the second endcap is greater than a size of the second rod receiving passageway.

### Claim 10 (depends on 1)

The implant of claim 1, wherein, in a cross section view, the rod comprises an oval shape.

### Claim 11 (depends on 10)

The implant of claim 10, wherein the first and second rod receiving passageways comprise an opening shaped like an oval, respectively.

### Claim 12 (depends on 1)

The implant of claim 1, wherein, in a cross section view, the rod comprises a circular shape.

### Claim 13 (depends on 12)

The implant of claim 12, wherein the first and second rod receiving passageways comprise an opening shaped like a circle, respectively.

### Claim 14 (depends on 1)

The implant of claim 1, wherein the first and second set screws are break off set screws.

### Claim 15

A method for installing a spinal implant, comprising:
providing a pre-assembled implant, comprising:
