摘要：A guide assembly for guiding a bone preparation tool in relation to a patient's

bone in an orthopaedic surgical procedure, includes a guide member which has a first face

which can be positioned against a surface of the bone which is to be prepared using a

bone preparation tool, and an opening extending through the guide member through

which the bone preparation tool can be positioned against the bone surface, and which

has one of a spigot and a socket formed on it. A location component comprises a locator

plate which, when attached to the guide member, extends from the guide member in the

direction in which the first face thereof faces, to engage a predetermined feature on the

bone so that the guide member can be located relative to the bone surface, and an

assembly arm which carries the other of the spigot and the socket so that the guide

member and the location component can be connected to one another by engaging the

spigot in the socket, after the guide member has been inserted through the surgical

incision, so that the location arm extends from the guide member in the general direction

in which the first face thereof faces. The locator plate defines a plane where it contacts

the bone and the spigot and socket define an assembly axis along which the spigot is

moved relative to the socket to be received in the socket. The angle between the locator

plate plane and the assembly axis is not more than about 10°.
