An impactor for use in securing an orthopaedic implant within a bone surface includes a shaft having a first end adapted to be impacted by a tool. The impactor further includes a head having a first end and a second end, wherein the first end of the head is connected to the second end of the shaft and a second end of the head includes an impaction surface. The head further includes an anti-rotation projection extending from the impaction surface and adapted for insertion within a groove formed by the implant to prevent rotation of the head and shaft when the head is in contact with the implant.
