Abstract
A hand-held surgical rotary impact tool and instrument extension for removing artificial hip, or acetabular, cups of a hip joint by rotating the cup a predetermined number of degrees. This rotational limitation is provided by a pin and arcuate groove connection between a fixed housing and rotatable shaft. While instrument extensions are sized to allow for different acetabular, or hip, cups, the cup engaging end can have radially adjustable pins for permitting a variable diameter for connection to a cup.
