Abstract

Claims (25)

1. A broach for shaping a bore in bone to receive an implant, the broach comprising:

a pyramid-shaped distal end with a terminal end that comprises first, second and third pyramid-shaped pointed tips each pointed distally, the distal end further comprising three distal end faces that taper distally and three distal end apices, each of the apices formed at a junction between adjacent distal end faces, each of the pointed tips which is disposed at an apex of the distal end; and

an elongate body portion extending proximally from the distal end, the elongate body portion comprising a longitudinal axis, exactly three faces, and exactly three apices each formed at the junction between adjacent faces, the first, second and third pyramid-shaped pointed tips disposed about the longitudinal axis,

the broach sized, configured and arranged to be withdrawn from the bone after shaping the bore.

2. The broach of claim 1 , wherein each of the three distal end faces transitions to one of the three faces of the elongate body portion.

3. The broach of claim 1 , further comprising a central lumen that extends to the pointed tips.

4. The broach of claim 1 , wherein the elongate body portion further comprises a plurality of side channels that extend along the longitudinal axis of the elongate body portion.

5. The broach of claim 4 , wherein each of the plurality of side channels is circumferentially in between elongate body apices.

6. A broach for shaping a bore in bone to receive an implant, the broach comprising:

a pyramid-shaped distal end; and

an elongate body portion extending proximally from the pyramid-shaped distal end, the elongate body portion comprising a longitudinal axis, exactly three faces and exactly three apices formed at the junctions between adjacent faces, the three apices of the elongate body portion having a constant radial dimension along the elongate body portion,

the pyramid-shaped distal end comprising exactly three distal end faces that taper in a distal direction, wherein each of the three distal end faces transitions to one of the three faces of the elongate body portion,

the pyramid-shaped distal end further comprising exactly three distal end apices, each of which is formed at a junction between adjacent distal end faces,

the pyramid-shaped distal end further comprising first, second and third tips, each of the tips each pointed distally to cut into bone, and each of the first, second and third tips disposed at one of the three distal end apices, and distributed about the longitudinal axis, and comprising two of the three distal end faces and a surface that extends proximally inward toward the longitudinal axis,

the broach sized, configured and arranged to be withdrawn from the bone after shaping the bore.

7. The broach of claim 6 , further comprising a central lumen that extends to the pyramid-shaped distal end.

8. The broach of claim 6 , wherein the elongate body portion further comprises a plurality of side channels that extend along the longitudinal axis of the elongate body portion.

9. The broach of claim 8 , wherein each of the plurality of side channels is circumferentially in between elongate body apices.

10. A method of using a broach to create a cavity for receiving a bone implant, the method comprising:

inserting a broach into bone, the broach comprising

a pyramid-shaped distal end with three distal end faces that taper in a distal direction, the distal end further comprising a terminal end that comprises first, second and third a plurality of tips pointed distally to cut into bone, each of which is disposed at an apex of the distal end, and each of the tips comprising two of the three distal end faces and a surface that extends proximally inward toward the longitudinal axis,

an elongate body portion extending proximally from the distal end, the elongate body portion comprising a longitudinal axis, exactly three faces, and exactly three apices each formed at the junction between adjacent faces;

cutting into the bone with the first, second and third plurality of tips pointed distally and forming a bore for an implant with an axially-directed non-rotational force;

removing the broach from the bone; and

positioning an implant within the bore.
