An example method includes obtaining, a virtual model of a portion of an anatomy of a patient obtained from a virtual surgical plan for an orthopedic joint repair surgical procedure to attach a prosthetic to the anatomy; identifying, based on data obtained by one or more sensors, positions of one or more physical markers positioned relative to the anatomy of the patient; and registering, based on the identified positions, the virtual model of the portion of the anatomy with a corresponding observed portion of the anatomy.

Devices and methods for use in a hip replacement surgical procedure. One aspect includes methods and devices for reaming selective regions of the femoral canal. This may include reaming distal and proximal sections of the femoral canal prior to reaming a middle region of the canal. Another aspect includes a dummy implant and methods of use. The dummy implant is inserted into the femoral canal and may be used for one or more of retraction of the femur, gauging a space with the acetabulum, and further revising the femoral cut. The aspects may be used together in a single surgical procedure or separately in different surgical procedures.

A system is disclosed herein for providing a kinetic assessment and preparation of a prosthetic joint comprising one or more prosthetic components. The system comprises a prosthetic component including sensors and circuitry configured to measure load, position of load, and joint alignment. The system further includes a remote system for receiving, processing, and displaying quantitative measurements from the sensors. The kinetic assessment measures joint alignment under loading that will be similar to that of a final joint installation. The kinetic assessment can use trial or permanent prosthetic components. Furthermore, adjustments can be made to the applied load magnitude, position of load, and joint alignment by various means to fine-tune an installation. The kinetic assessment increases both performance and reliability of the installed joint by reducing error that is introduced by elements that load or modify the joint dynamics not taken into account by prior assessment methods.

Embodiments of the invention include devices and methods for implanting arthroplasty devices. Some embodiments include designs that allow for use of x-ray images as the only images used to fully and accurately preoperatively and intraoperatively size and align arthroplasty device components and prepare all necessary tissue.

Patient-specific systems and methods are provided for assisting in medical procedures, and can include producing patient-specific devices from computer models of a patient's anatomy, including a first patient-specific device configured to identify and allow access to a resection area in an operation location for a medical procedure; a second patient-specific device configured to refine the procedure, following use of the first patient-specific device and in some embodiments, to identify and allow access to installation locations for an implant and/or surgical hardware; and/or a third patient specific device configured to assist in confirming placement of the implant and/or surgical hardware and refining the procedure, following use of the first and second patient-specific devices. Each of these devices may be developed from patient-specific computer model data via patient-specific image data and may enhance a variety of procedures.

Methods, systems and devices for pre-operatively planned shoulder surgery guides and implants. Pre-operative planning methods for designing glenoid placement guides and depth-control pins based on considerations of multiple factors affecting the outcome of shoulder surgery. Methods of using surgery guides and implants, including glenoid placement guides and depth-control pins, in patients undergoing shoulder surgery.

Systems and methods are described to determine joint center of rotation during a procedure. Joint center measurements may be useful to determine other clinically relevant measurements and/or to assist with replacement surgery.

Hip joint navigation systems and methods are provided. In some embodiments, the systems and methods described herein determine a table reference plane that approximates the Anterior Pelvic Plane. In some embodiments, the systems and methods described herein measure a pre-operative and post-operative point. In some embodiments, the comparison of the pre-operative and post-operative point corresponds to changes in leg length and joint offset. In some embodiments, the systems and methods described herein determine an Adjusted Plane. In some embodiments, the Adjusted Plane adjusts for tilt by rotating the Anterior Pelvic Plane about the inter-ASIS line. In some embodiments, the Adjusted Plane improves correlation between navigated cup angles and post-operative images.

The present disclosure includes systems, methods, kits, and individual tools (e.g., trial sizers and delivery devices) for medical procedures involving a soft-tissue allograft for the correction of skeletal impairments (e.g., misalignments, arthritis, etc.).

A prosthetic device can include a neck defining an upper surface and a sidewall extending from the upper surface, an opening defined by the sidewall and extending into the neck, one or more interior surfaces extending into the neck from the opening to define a female receiving cavity, and a radial head including a male protrusion received within the female receiving cavity through the opening.
