## Abstract

The present invention is an implant for bone. The current implant is particularly useful in spinal surgical procedures.

## Claims

### Claim 1

An implant for bone adapted for interconnection with a device distinct from the implant; the implant comprising:
a) a shaft comprising a first end and a second end opposite the first end; and
b) a surgical cutting wedge connected to the first end of the shaft; the surgical cutting wedge comprising:
i) a first planar surface and a second planar surface;
ii) a first side connected with and perpendicular to the shaft, wherein the first side comprises a first end of greater height than an opposed second end of first side;
iii) a second side parallel to the first side, wherein a first end is of greater height than an opposed second end of second side;
iv) a planar third side extending between the first and second planar surfaces and first and second sides, wherein connection angles of first and second sides with opposed ends of the planar third side are identical; and
v) a cutting edge opposed from and parallel to the planar third side; the cutting edge connected to the first planar surface, the second planar surface and the second ends of the first and second sides.

### Claim 2 (depends on 1)

The implant of claim 1, wherein the cutting edge comprises a bevel.

### Claim 3 (depends on 2)

The implant of claim 2, wherein the first and second planar surfaces are parallelograms.

### Claim 4 (depends on 3)

The implant of claim 3, wherein elevations of the cutting edge are graduated from a greater height to a lesser height as the cutting edge traverses from an outward margin of the second end of the second side toward outward margin of the second end of the first side.

### Claim 5 (depends on 3)

The implant of claim 3 further comprising a polyaxial head connected to the second end of the shaft.

### Claim 6 (depends on 3)

The implant of claim 3, wherein the second end of shaft comprises a thread.

### Claim 7

An implant for bone adapted for interconnection with a device distinct from the implant; the implant comprising:
a) a surgical cutting wedge comprising:
i) a first planar surface and a second planar surface;
ii) an interconnected combination of a first side, a second side and a third side; the interconnected combination of the first, second and third sides extending between and connected to the first and second planar surfaces, wherein: the first side comprises a first end of greater height than an opposed second end of first side; and the second side comprises a first end of greater height than an opposed second end of second side; and
iii) a cutting edge connected to the first and second planar surfaces and the second ends of the first and second sides such that the cutting edge is adapted to cut in perpendicular, clockwise and counterclockwise directions relative to a shaft; and
b) a first end of the shaft connected to the first side at a position between the opposed cutting edge and third side of the surgical cutting wedge.

### Claim 8 (depends on 7)

The implant of claim 7, wherein the cutting edge comprises a bevel.

### Claim 9 (depends on 8)

The implant of claim 8, wherein the first and second planar surfaces are parallelograms.

### Claim 10 (depends on 9)

The implant of claim 9, wherein elevations of the cutting edge are graduated from a greater height to a lesser height as the cutting edge traverses from an outward margin of the second end of the second side toward outward margin of the second end of the first side.

### Claim 11 (depends on 9)

The implant of claim 9 further comprising a polyaxial head connected to the second end of the shaft.

### Claim 12 (depends on 9)

The implant of claim 9, wherein the second end of shaft comprises a thread.
