20130158607Apparatus and Methods for Repairing Craniomaxillofacial Bones Using Customized Bone Plates - Bone plates and methods of using the bone plates for adjoining bone fragments are disclosed herein. A device for adjoining at least two bone fragments includes a delivery catheter having an elongated shaft with a proximal end, a distal end, and a longitudinal axis therebetween, wherein the delivery catheter has an inner void for passage of at least one filling material and an inner lumen for passage of a light source; a conformable bone plate releasably engaging the distal end of the delivery catheter, wherein the conformable bone plate has a first surface, a second surface, a proximal end, and a distal end and at least one aperture extending from the first surface to the second surface for receiving a fastener; and an adapter releasably engaging the proximal end of the delivery catheter for receiving the light source and a delivery system housing the at least one filling material.06-20-2013
20130184764PATIENT-SPECIFIC HIGH TIBIA OSTEOTOMY - A surgical method for tibia osteotomy includes attaching a patient-specific alignment guide to a corresponding surface of a tibia of a patient for whom the alignment guide is customized during a pre-operative planning stage and making a partial bone cut in the tibia through a planar slot of the alignment guide. The planar slot is oriented at a patient-specific angle relative to an anatomic axis of the patient and the angle is customized during the pre-operative planning stage. The method includes opening the bone cut to form an opening wedge, and inserting a patient-specific implantable wedge into the opening wedge.07-18-2013
20120029574ORTHOGNATHIC IMPLANT AND METHODS OF USE - An implant for use in orthognathic surgery of a mandible may include a longitudinal plate member and a plurality of pre-configured guides coupled to the plate member. The longitudinal plate member is pre-bent to correspond to the post-operative shape of the mandible; and the guides are pre-configured to align the plate member with the mandible when the implant is positioned against the mandible after the mandible has been separated.02-02-2012
