    Abstract: The present invention provides an improved contourable surgical fixation device that is made from a resorbable material and useful in bone reconstruction. In one embodiment, the fixation device may be made of a polymeric material. The fixation device comprises a plurality of spaced-apart fastening plates, links interconnecting the plates, and openings defined between the fastening plates by the links and fastening plates. In one embodiment, at least some of the fastening plates have fastener holes therethrough for receiving a fastener, such as a screw or tack, to secure the fixation device to the bone. The present invention provides an open-structured fixation device that is capable of being contoured in three dimensions to approximate the anatomical shape of a bone to which the fixation device may be attached.
