An adaptor/holder ( 40 ) is described which attaches to the front ( 18 ) of an existing orthopedic inserter/impactor handle ( 10 ) via the handle's existing threaded interface mechanism ( 22 ). The adaptor/holder ( 40 ) has an annular housing ( 42 ) that snaps onto the front ( 18 ) of the existing inserter ( 10 ), and has an internal yoke and pin assembly ( 70 ) that attached to the handle's interface mechanism ( 22 ). The holder ( 40 ) adapts the inserter ( 10 ) to much more easily and quickly release from a prosthetic component ( 12 ) after the component ( 12 ) is surgically implanted in a patient, and with less mechanical manipulation than could otherwise be accomplished using the inserter ( 10 ) alone. The adaptor/holder utilizes the inserter's existing mount tensioning (draw piston) mechanism ( 30 ) to quickly engage and disengage the prosthetic component ( 12 ). Upon activation of the inserter's tensioning mechanism ( 30 ), the holder ( 10 ) receives and fixes a prosthetic component ( 12 ) to the end ( 18 ) of the inserter ( 10 ). Deactivation of the inserter handle's tensioning mechanism ( 30 ) quickly accomplishes release of the prosthetic component ( 12 ) with minimal manipulation.
