An orthopaedic surgical instrument assembly for use in the surgical preparation of a glenoid of a patient prior to implantation of an augmented glenoid prosthesis includes an oscillating surgical rasp having an attachment head configured to be secured in a chuck of an oscillating tool, and a cutting head secured to attachment head. The cutting head has a cutting surface extending posteriorly from the longitudinal axis of the oscillating surgical rasp, with a plurality of cutting teeth arranged in a geometry that, when oscillated along a predetermined path in contact with the glenoid of the patient, corresponds with the geometry of the augmented glenoid prosthesis. A rasp guide has a guide surface configured to guide the oscillating surgical rasp along the predetermined path in contact with the glenoid of the patient, and an anchor surface that is opposite the guide surface and configured to be secured to the glenoid of the patient. |
