Abstract

Abstract Systems and methods are provided for designing and producing custom-made templates for implantation or for pre-contouring metallic or polymer implantable plates prior to surgery. According to one embodiment, medical image data representing surrounding portions of a patient's anatomy to be repaired by surgical implantation of a bone reconstruction plate is received. Next, three-dimensional surface reconstruction is preformed based on the medical image data. Virtual removal of a bone or portion thereof to be reconstructed is performed with reference to the medical image data by simulating the contemplated surgical implantation procedure. Then, a representation of a template is created that is countered to fit the patient's anatomy to be repaired. Finally, a replica of the template is produced by using Solid Freeform Fabrication manufacturing techniques.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 102 words
A method of producing a template for use in pre-contouring bone reconstruction plates, the method comprising: receiving medical image data representing surrounding portions of a patient's anatomy to be repaired by surgical implantation of a bone reconstruction plate; performing three-dimensional surface reconstruction based on the medical image data; performing virtual removal of a bone or portion thereof to be reconstructed with reference to the medical image data by simulating the surgical implantation procedure; creating a representation of a template contoured to fit the patient's anatomy to be repaired; and outputting a replica of the template by using Solid Freeform Fabrication manufacturing techniques.
