an adaptor / holder is described which attaches to the front of an existing orthopedic inserter / impactor handle via the handle &# 39 ; s existing threaded interface mechanism . the adaptor / holder has an annular housing that snaps onto the front of the existing inserter , and has an internal yoke and pin assembly that attached to the handle &# 39 ; s interface mechanism . the holder adapts the inserter to much more easily and quickly release from a prosthetic component after the component is surgically implanted in a patient , and with less mechanical manipulation than could otherwise be accomplished using the inserter alone . the adaptor / holder utilizes the inserter &# 39 ; s existing mount tensioning mechanism to quickly engage and disengage the prosthetic component . upon activation of the inserter &# 39 ; s tensioning mechanism , the holder receives and fixes a prosthetic component to the end of the inserter . deactivation of the inserter handle &# 39 ; s tensioning mechanism quickly accomplishes release of the prosthetic component with minimal manipulation .
