A device and method of loading a bone anchor into a bone-anchor inserter does not apply force on the leading point, the distal cutting edges or threads of the bone anchor. The bone-anchor loading device may, for example, include a main body including a gripping portion and, projecting therefrom, an elongated bone-anchor receiving member having a receiver fitting at a distal end thereof; an elongated sleeve coaxially disposed over the anchor-receiving member and configured for slidable translation thereover; and an interference fitting causing engagement between the sleeve and the anchor-receiving member when the sleeve is translated to an interference position with respect to the main body, the engagement further causing the receiver fitting to deform to releasably secure a bone anchor.
A method of loading a bone anchor into a bone-anchor inserter, the bone anchor having a shank with a distal end, the method comprising the steps of:
The method of claim 2 wherein the operating step further comprises forcing the distal end of the sleeve proximally toward the gripping portion of the main body to thereby relieve the interference fit and release the bone anchor from the bone-anchor loading device.
