1. An orthopaedic fastening system comprising:
an orthopaedic implant having an inner surface defining a bore; and
an orthopaedic locking screw configured to be secured through the bore of the orthopaedic implant into a bore drilled into bone, the orthopaedic locking screw comprising:
a shaft extending along an axis between a first end a second end;
a casing secured to and rotationally fixed around an outer surface of the shaft to prevent rotational movement of the casing relative to the shaft as the casing is secured through the bore of the orthopaedic implant, wherein the casing has an outer cross-sectional width that is larger than a smallest inside cross-sectional width of the bore of the orthopaedic implant, and wherein the casing is formed of a material that is at least partially plastically deformable such that, during securing of the orthopaedic locking screw through the bore of the orthopaedic implant, the casing is plastically deformed so as to operably engage the casing with the orthopaedic implant and, thereby, allow the orthopaedic locking screw to advance through the bore of the orthopaedic implant;

wherein the first end of the shaft has an outer cross-sectional width that is smaller than a smallest inside cross-sectional width of the bore of the orthopaedic implant.
