Abstract
An orthopedic locking screw is be configured to be retained inside the bore of an orthopedic implant provided as part of an orthopedic fastening system. The orthopedic locking screw includes a shaft extending axially, a drive member, and a casing secured around an outer surface of the shaft. The casing is formed of a plastically deformable material. The casing has an outer cross-sectional width that is larger than a cross-sectional width of the shaft adjacent the casing. When operably disposed in the bore, an axial and/or radial press-fit pressure is formed between the casing and the bore. A method of securing an orthopedic screw in a bore of an orthopedic implant is provided, in which the shaft is rotated to operably engage the casing to the bore to achieving a deformable press-fit of the casing against the bore.
