## Abstract

A screw includes a screw head having a bevel and an elongate shaft attached to the screw head. The shaft has a central longitudinal axis. A tip is attached to the shaft, distal from the head. A method in implanting the screw into a bone or bone fragment is also disclosed.

## Claims

### Claim 1

A screw comprising:
a screw head having a bevel, wherein the bevel forms a dome shape;
an elongate shaft attached to the screw head, the shaft having a central longitudinal axis and a cannula extending along the longitudinal axis; and
a tip attached to the shaft, distal from the head,
wherein the screw head and the shaft are solid around the cannula, and
wherein the screw is fully threaded.

### Claim 2 (depends on 1)

The screw according to claim 1, wherein a top end of the thread terminates at the bevel.

### Claim 3 (depends on 1)

The screw according to claim 1, wherein the thread is continuous around the screw head.

### Claim 4 (depends on 1)

The screw according to claim 1, wherein the screw head arcs with a constant radius of curvature, forming the dome shape.

### Claim 5 (depends on 4)

The screw according to claim 4, wherein the radius is between about 5 mm and about 15 mm.

### Claim 6 (depends on 1)

The screw according to claim 1, wherein the head comprises a trailing end.

### Claim 7 (depends on 6)

The screw according to claim 6, wherein the trailing end spans an arc of about 15 degrees.

### Claim 8 (depends on 1)

The screw according to claim 1, wherein the screw head is elliptical in shape.

### Claim 9 (depends on 1)

The screw according to claim 1, wherein the screw anticipates an insertion angle of 40 degrees.

### Claim 10 (depends on 1)

The screw according to claim 1, further comprising a plurality of flutes formed along an exterior of the shaft.

### Claim 11 (depends on 10)

The screw according to claim 10, wherein the flutes extend the length of the shaft.

### Claim 12 (depends on 10)

The screw according to claim 10, wherein three flutes are evenly spaced 120 degrees apart from each other around the exterior of the shaft.

### Claim 13 (depends on 10)

The screw according to claim 10, wherein the flutes extend helically around the shaft.
