A surgical instrument includes a finishing rasp having a longitudinal axis, an elongated shaft, a handle, and a cutting head. The elongated shaft has an outer circumference and a bore formed therein, and the bore has an open end defined in a distal end of the elongated shaft and a blind end positioned proximally of the open end within the elongated shaft. The handle is secured to an opposite, proximal end of the elongated shaft. The cutting head is secured to, and extends away from, the distal end of the shaft. The cutting head has a length that extends along the longitudinal axis and is arcuate in shape so as to extend around less than the outer circumference of the elongated shaft at the open end of the bore. The cutting head includes a plurality of linear cutting teeth that extend along the length of the cutting head.

1. A surgical instrument for use during a surgical procedure to implant an orthopaedic hip prosthesis, comprising: a finishing rasp comprising (i) an elongated shaft that extends along a longitudinal axis and has an outer circumference and a bore formed therein, the bore having a center line that lies on the same line as the longitudinal axis, an open end that is on the center line and defined in a distal end of the elongated shaft, and a blind end positioned proximally of the open end within the elongated shaft, (ii) a handle secured to an opposite, proximal end of the elongated shaft, and (iii) a cutting head secured to, and extending away from, the distal end of the shaft,wherein the cutting head has a length that extends parallel to the longitudinal axis, a concave first side that faces the longitudinal axis, and a second side that faces away from the longitudinal axis,wherein the cutting head is arcuate in shape so as to extend around less than the outer circumference of the elongated shaft at the open end of the bore,wherein the cutting head comprises a plurality of linear cutting teeth that are positioned on the second side and that face away from the longitudinal axis, andwherein each tooth has an elongated body that extends along the length of the cutting head. 2. The surgical instrument of claim 1, wherein the handle is irremovably secured to the elongated shaft. 3. The surgical instrument of claim 1, wherein: the handle is positioned on the elongated shaft such that a first end of the handle is positioned on a first side of the shaft and is spaced apart from the shaft by a distance that is less than the distance a second end of the handle is spaced apart from the shaft, andthe cutting head is positioned on the first side of the elongated shaft. 4. The surgical instrument of claim 1, wherein the finishing rasp further comprises a depth stop positioned in the blind end of the bore. 5. The surgical instrument of claim 1, wherein the cutting teeth of the cutting head are configured to cut bone tissue when the cutting head is advanced with oscillating motion in two directions. 6. A finishing rasp for use during a surgical procedure to implant an orthopaedic hip prosthesis, comprising: an elongated shaft that extends along a longitudinal axis and has an outer circumference and a bore formed therein, the bore having (i) a center line that lies on the same line as the longitudinal axis, (ii) an open end that is on the center line and is defined in a distal end of the elongated shaft, and (iii) a blind end positioned proximally of the open end within the elongated shaft,a handle secured to an opposite, proximal end of the elongated shaft, anda cutting head secured to, and extending away from, the distal end of the shaft, the cutting head having a length that extends parallel to the longitudinal axis, a concave first side that faces the longitudinal axis, and a second side that faces away from the longitudinal axis, wherein the cutting head is arcuate in shape so as to extend around less than the outer circumference of the elongated shaft at the open end of the bore, the cutting head comprising a plurality of linear cutting teeth that face away from the longitudinal axis, wherein each tooth has an elongated body that extends along the length of the cutting head and is configured to cut bone tissue when the cutting head is advanced with oscillating motion in two directions along the longitudinal axis. 7. The finishing rasp of claim 6, wherein: the handle is positioned on the elongated shaft such that a first end of the handle is positioned on a first side of the elongated shaft and is spaced apart from the shaft by a distance that is less than the distance a second end of the handle is spaced apart from the shaft, andthe cutting head is positioned on the first side of the elongated shaft. 8. The finishing rasp of claim 6, wherein the handle is irremovably secured to the elongated shaft. 9. The finishing rasp of claim 6, further comprises a depth stop positioned in the blind end of the bore.
