A number of orthopaedic surgical instruments are disclosed. A method, apparatus, and system for fabricating such instruments are also disclosed.

Apparatus and method for fabricating a customized patient-specific orthopaedic instrument

A model production device generates one or more contact bodies of a patient-specific surgical instrument model based on a parameterized model of a patient's bone. The parameterized model includes a predetermined number of polygons each having a predetermined position relative to the patient's anatomy. The parameterized model may be generated based on a three-dimensional model that was generated based on multiple images of the patient's bone. The model production device adds parametric fixed geometry to the patient-specific surgical instrument model based on the parameterized model and subtracts the three-dimensional model of the patient's bone from the patient-specific surgical instrument model. Each contacting body may be positioned at a high-confidence part of the parametric model, and the parametric fixed geometry may be positioned at a low-confidence part. A patient-specific surgical instrument may be manufactured based on the patient-specific surgical instrument model.

Customized patient-specific orthopaedic surgical instrument using patient-specific contacting bodies and parametric fixed geometry

A system and method for validating an orthopaedic surgical plan includes a data tag associated with a patient-specific orthopaedic surgical instrument and a data reader to read the data tag to obtain surgical procedure parameters from the data tag. A display module may display the surgical procedure parameters and/or identification data to validate the patient-specific orthopaedic surgical instrument. Additionally, the system may include a sensor module to generate joint force data indicative of a joint force of a patient's joint. The display module may be configured to display the joint force data in association with the surgical procedure parameters.

System and method for validating an orthopaedic surgical plan

A number of orthopaedic surgical instruments are also disclosed. A method, apparatus, and system for fabricating such instruments are also disclosed.

A surgical instrument including a customized patient-specific guide block is disclosed. The customized patient-specific guide block includes a first surface, a bone-facing surface, a second surface positioned opposite the first surface and the bone-facing surface, and a guide pin hole extending between the second surface and the bone-facing surface. The first surface has a customized prosthesis-specific negative contour shaped to match a corresponding contour of a prosthetic component, and the customized prosthesis-specific negative contour includes a concave surface shaped to match a convex surface of the corresponding contour of the prosthetic component. A method of performing an orthopedic surgical procedure is also disclosed.

Customized patient-specific revision surgical instruments and method

A number of orthopedic surgical instruments are also disclosed. A method, apparatus, and system for fabricating such instruments are also disclosed.

Method of fabricating customized patient-specific bone cutting blocks

A system and method includes a data tag associated with a patient-specific orthopedic surgical instrument and a data reader to read the data tag to obtain surgical procedure parameters from the data tag. A display module may display the surgical procedure parameters and/or identification data to validate the patient-specific orthopedic surgical instrument. Additionally, the system may include a sensor module to generate joint force data indicative of a joint force of a patient's joint. The display module may be configured to display the joint force data in association with the surgical procedure parameters.

An x-ray calibration apparatus includes a radiolucent knee alignment jig configured to receive a knee of a patient and a radiolucent cushion configured to hold a patient's knee at a fixed angle of flexion. The x-ray calibration apparatus also includes a number of radio-opaque fiducial markers positioned within the radiolucent knee alignment jig.

Apparatus and method for calibrating an x-ray image of a knee of a patient

A method of fabricating a customized patient-specific guide block is disclosed. The method includes generating a image of a patient's bony anatomy and an implanted prosthetic component secured to the patient's bony anatomy, identifying landmarks on the patient's bony anatomy and the prosthetic component, selecting a revision surgical instrument based the image and the landmarks, and manufacturing the customized patient-specific guide block including a customized prosthesis-specific negative contour shaped to match a corresponding contour of the implanted prosthetic component.

Customized patient-specific bone cutting blocks

Customized patient-specific orthopedic surgical instruments are disclosed. Methods for fabricating and using such instruments are also disclosed.

Customized patient-specific orthopaedic pin guides

A surgical instrument including a customized patient-specific guide block is disclosed. The customized patient-specific guide block includes a first surface, a bone-facing surface, a second surface positioned opposite the first surface and the bone-facing surface, and a guide pin hole extending between the second surface and the bone-facing surface. The first surface has a customized prosthesis-specific negative contour shaped to match a corresponding contour of a prosthetic component, and the customized prosthesis-specific negative contour includes a concave surface shaped to match a convex surface of the corresponding contour of the prosthetic component. A method of performing an orthopaedic surgical procedure is also disclosed.
