摘要：
Reciprocating rasps for the surgical preparation of the bone prior to the implantation of a glenoid or acetabular component with complex geometry are disclosed. Surgical methods for the use of such reciprocating rasps are also disclosed. A reciprocating rasp for use in the surgical preparation of a glenoid includes a shaft having a first end configured to be secured in a chuck of a reciprocating tool, and a cutting head secured to a second end of the shaft. The cutting head includes a cutting surface having a plurality of cutting teeth arranged in a geometry that corresponds with a geometry of the glenoid prosthesis, and an inwardly curved concave guide surface that is devoid of cutting teeth and configured to receive a guide pin inserted in the glenoid of the patient when the cutting head is secured to the second end of the shaft.
