Patent number: 9895230Abstract: A method for generating a patient-specific prosthetic implant is disclosed which includes generating, using one or more processors from a medical image of a human anatomical feature, a three dimensional electronic representation of the human anatomical feature including size and surface curvature features matching the human anatomical feature, the surface curvature features including one or more radii of curvature on an outer camming surface of the human anatomical feature. A prosthetic implant template is selected, using the one or more processors, from a database of prosthetic implant templates, and the custom implant is virtually designed to imitate the size and surface curvature features of the three dimensional electronic representation based on the selected prosthetic implant template. Fit of the custom implant is tested, virtually using the one or more processors, using the three dimensional electronic representation of the human anatomical feature.Type: GrantFiled: September 13, 2016Date of Patent: February 20, 2018Assignee: ZIMMER, INC.Inventor: Mohamed Rashwan Mahfouz

Patent number: 9675461Abstract: A method of designing a prosthetic implant. Exemplary methods may include developing a three-dimensional model of an anatomic feature from one or more two-dimensional images. The three-dimensional model may include a plurality of radii of curvature representing the shape of respective portions of a contact surface. In some exemplary embodiments, three-dimensional models associated with a large number members of a population may be utilized to create templates for prosthetic implants. A three-dimensional model of an anatomic feature of a patient may be compared to the available templates, and a suitable template may be tested by virtually implanting the template on the three-dimensional model of the patient's anatomical feature. In some embodiments, a patient's three-dimensional model for which a suitable pre-made template is not available may be used to customize a pre-made template to design a suitable implant.Type: GrantFiled: March 6, 2015Date of Patent: June 13, 2017Assignee: ZIMMER INC.Inventor: Mohamed Rashwan Mahfouz
