Abstract
An instrument for hip arthroplasty having an impaction body attached to an end of a main body. The impaction body is positionable inside a patient's hip and has an axis coaxial with an impaction axis. A leading end of the impaction body is configured to selectively engage an acetabular shell for use during impaction of the shell into an acetabulum. An arm extends from the main body and has a guide ring at an end thereof. The guide ring has an axis coaxial with the impaction axis. A trocar is inserted through the guide ring and along the impaction axis to make a path through underlying soft tissue for insertion of an impacting instrument. A rotatable handle on the main body indicates whether the main body is in a proper position in either a right or left hip.
