Instrument and method for seating a prosthesis

摘要

Instruments and a method are provided for reducing the gap between an implant head and the underlying resected bone surface to produce a more anatomic joint reconstruction. This is accomplished by providing a reamer for counter boring the resected surface to receive the collar so that a portion of the collar is recessed into the resected surface. The present invention permits the flexibility and stability of a collared two-piece implant while maintaining the close fit of a unitary implant.
