Systems and methods for creation of anatomically correct physical models for an individual patient are provided. More specifically, the embodiments of the present invention relate to systems and methods for design and manufacture of a modified bone model including an accurate soft tissue model. Medical image acquisition processes are used to capture data representative of an anatomy and a scan prosthesis. A modified bone model with supports is designed and fabricated. The modified bone model and scan prosthesis (or copy thereof) is then used to generate the soft tissue model.

Systems and methods are provided for designing and producing a custom-fit prosthesis. According to one embodiment, a mold is produced from which a custom-fit implant may be directly or indirectly manufactured. Medical image data representing surrounding portions of a patient's anatomy to be repaired by surgical implantation of the custom-fit implant are received. Then, three-dimensional surface reconstruction is performed based on the medical image data. Next, the custom-fit implant is designed based on the three-dimensional surface reconstruction and a positive or negative representation of a two-part mold is created with a void in the shape of the custom-fit implant by subtracting a representation of the custom-fit implant from a representation of a mold. Finally, the two-part mold is output from which the custom-fit implant may be directly manufactured; or an implant is directly output. Alternatively, an intermediate mold is created from which a two-part mold may be directly manufactured.

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.
