Disclosed herein are orthopedic revision systems including a base member having a collar portion and at least one stabilization portion extending outwardly from the collar portion. The systems may further include a stem member having an attachment portion and a shaft portion, the stem member configured to be received at least partially through an opening in the collar portion such that the attachment portion lies adjacent the collar portion and the shaft portion lies adjacent the at least one stabilizing portion. In a method of performing revision surgery with such orthopedic systems includes forming an opening in the collar of the base member for receipt of the stem member by removing an inner portion of the collar portion and inserting the stem member at least partially through the opening in the collar portion such that the attachment portion lies adjacent the collar portion and the shaft member lies adjacent the at least one stabilizing portion.

Reviseable stemless prostheses and methods

An insertion instrument for inserting an orthopedic implant into a bone and guiding an implant attachment element into the bone comprising: a body having a first end and a second end and a bore extending along a central axis; a fixed arm and a deflectable arm coupled to the body second end, the fixed arm spaced from the deflectable arm forming an attachment element receiving passageway therebetween extending along the central axis, the fixed arm having an implant engaging free end spaced a fixed distance from the central axis; and an actuator mounted on the first end of the body for moving the deflectable arm away from the fixed arm while allowing the attachment element to traverse the passageway.
