Abstract

A biocompatible and pliable metallic surgical implant plate for use in the repair and rigid fixation of internal fractures of the floor and walls of the orbit. The implant plate includes an elongated base portion which is compliant for shaping to interface with the rim structure of the orbit. Three perforated leaf portions, spaced from one-another, project rearwardly from the elongated base portion. The central leaf portion is compliant for shaping to conform to the configuration of the orbit floor, one of the outboard leaf portions is compliant for shaping to conform to the medial wall of the orbit and the other outboard leaf portion is compliant for shaping to conform to the lateral wall of the orbit. Attachment legs, including screw holes, project forwardly from the elongated base portion of the implant plate and are compliant for shaping and fitment to the anterior face of the rim structure of the orbit with the implant plate being affixed to the rim structure of the orbit by bone screws applied through the screw holes of the attachment legs. Alternatively, an orbital rim reinforcing bar, including screw holes, may be attached to the elongated base portion of the implant plate by a series of legs. The leaf portions of the implant plate may be provided with a thin coating of biocompatible synthetic sheathing material to inhibit the ingrowth of hard and soft tissue into the perforation of the leaf portions.
