An implantable plate for providing support to a bone of a subject when affixed thereto includes a polymeric body of a biocompatible polymer having a desired amount of polymer molecule orientation in a first direction so that the plate can be bent to conform with a contour of the bone of the subject. The polymeric body includes a top surface, a bottom surface, and at least one fastener portion. The fastener portion includes a recess and a fastener hold that is configured for receiving a fastener when affixed to the bone of the subject. A method of manufacturing the implantable plate includes: (1) injection molding a biocompatible polymeric composition into a polymeric body within an injection mold; (2) removing the polymeric body from the injection mold; and (3) forming at least one fastener hole within polymeric body.
