1. A pin plate assembly comprising: a pin plate adapted for being secured to a bone, said pin plate having at least a first pin hole extending therethrough, a pin member comprising a pin, said pin being insertable in said at least first pin hole to extend therethrough to an operative position in which a first portion of the pin engages a fragment of the bone, said pin comprising a plurality of portions, including the first portion and a second portion, arranged to enter said pin hole in succession as the pin is longitudinally advanced in the pin hole from a first position, wherein the first portion has not yet advanced through the pin plate, to the operative position, wherein the first portion has advanced through the pin plate and engaged the bone fragment, said first portion having a shape and dimension with respect to said pin hole, including a diameter that is smaller than a diameter of the pin hole, so as to travel substantially freely through the pin hole from the first position to the operative position as the pin is longitudinally advanced in the pin hole, said second portion being shaped and dimensioned with respect to said pin hole such that the second portion enters but does not exit the pin hole when the pin is longitudinally advanced into the pin hole from the first position to the operative position, respective dimensions of said pin and pin plate being such that the pin, the pin plate or both elastically deform when the second portion is longitudinally advanced into the pin hole so that the second portion of the pin engages the pin plate in an interference fit when the second portion is positioned in the pin hole.
