Abstract: A method of forming a patient-specific-bone-graft cage based on a patient-specific bone graft cage computer model that is based on a contour of a surface of the bone defining a void, and/or a patient-specific-bone-graft cage that includes a plurality of apertures, that terminate at a location between a front surface and a back surface of the patient-specific-bone-graft cage, for receipt of bone graft material. The patient-specific-bone-graft cage can construct an essential portion (including complex thin anatomical structures) of or substantially the entirety of the mid-face region (e.g., to fill a void in a damaged orbital region), which enables an improved structure reproduction and simplification for the surgeon. For example, the patient-specific-bone-graft cage may be formed based on the contour of the periphery defining the void in the damaged region, and require less modification by a surgeon compared to graft cages formed only by mirroring techniques or normalized models.
