A61B 17/16
A61B 17/17

Abstract:

A method of performing joint arthroplasty includes accessing a surface on a bone and supporting a stop with the accessed surface. The method includes positioning an instrument at least partially within the stop, the instrument having a body and a punch, the punch including a portion thereof having a shape similar to a shape of a stem of an implant, and rotating the stop with respect to the accessed surface based upon an indicia on one of the body and the stop so as to position the punch rotationally with respect to the accessed surface at a first orientation. The method further includes moving the body axially with respect to the stop to form a cavity in the bone with the punch at the first rotational orientation, the formed cavity having a shape similar to the stem of the implant, and implanting the stem of the implant into the cavity.

Abstract:

A method of performing joint arthroplasty includes preparing a flat surface on a long bone, providing an instrument having a body and a punch extending from the body, the punch including a portion thereof having a shape similar to a stem of an implant, positioning a stop on the flat surface, rotating the stop with respect to the surface of the long bone based upon an indicia on one of the body and the stop so as to position the punch rotationally with respect to the surface to a desired orientation when the instrument is at least partially inserted into the stop, using the instrument to form a cavity in the long bone with the punch at the desired rotational orientation with the instrument inserted at least partially within the stop, the cavity having a shape similar to the stem of the implant, and implanting the stem into the cavity.
