IMPLANT DEVICES CONSTRUCTED WITH METALLIC AND POLYMERIC COMPONENTS

摘要

An intramedullary nail includes a longitudinal core (102) extending along a longitudinal axis from a proximal portion of the nail to a distal portion thereof, the core including a plurality of interlocking features (116) around a circumference thereof and a polymeric casing (104) extending about at least a portion of the circumference of the core in¬ cluding the interlocking features to mechanically interlock the casing and the core, at least a portion of a length of the core being embed¬ ded within the casing offset from a longitudinal axis of the nail so that a thickness of casing varies about a circumference of the nail, a max¬ imum thickness of the casing being located at a site at which a poly¬ meric locking element is to be bonded to the nail.
