Abstract
The acetabular cup positioner of this invention provides for a sighting guide which is removable connected to the shaft of the cup positioner by a tapered locking configuration. The taper lock provides for a secure connection of the sighting guide to the shaft of the cup positioner which enhances the accuracy of the device. The taper lock provides such a strong lock that in order to provide for its removal, the cup positioner of the invention includes a slaphammer carrier on the shaft of the guide which may be employed by the surgeon to remove the guide from the positioner without undue effort.
