Perforated metallic panels and strips for internal fixation of bone fractures and for reconstructive surgery

摘要

A pliable metallic mesh implant plate structure for the internal fixation of bone fractures and for use in orthognathic and reconstructive surgery. The plate structure includes a multiplicity of substantially square perforations (12) extending from the outer face side of the plate structure to the bone interface side thereof and arranged uniformly in parallel rows and parallel lines. Each perforation (12) includes an arcuate chamfer of substantially uniform configuration extending inwardly from the outer face side of the plate structure to the bone interface side about the entire periphery thereof. Thus, when bone screws (18) having a screw head configuration (22) including a hemispherical underside portion and low profile upper head portion, are applied through the perforations (12) of the mesh plate structure from the outer face side and screwed into the bone proximate the bone interface side thereof, with the screw head (22) seated in congruent fitment in the perforation (12), there is presented a relatively non-obtrusive surface at the face side of the plate structure.
