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.

A medical guidance apparatus (100) includes a base assembly (110) configured to be attached to a subject and a guide (150) configured to be removably mated with the base assembly (110). The base assembly (110) has an opening (160), and the guide (150) includes a rotatable ring (152) and an arc member (154). The arc member (154) includes a first end (162) and a second end (164), the first end of the arc member is connected to the rotatable ring (152) and the second end extends diametrically opposite to the first end across the rotatable ring. A probe holder (600) is mounted on the arc member (154) so as to hold a needle-like instrument (2161) at a desired angle relative to an axis (Ax) of the rotatable ring (152). In some embodiments, the arc member is monolithically integrated with the rotatable ring. In other embodiments, the arc member is pivotable and/or completely removable from the rotating ring.

Orthopedic systems and methods are provided for use in preparing joints for implants. Specifically, hip preparation systems and methods are disclosed which can include a surgical orientation device. The hip preparation systems and methods can be used, for example, to orient the hip during the procedure, determine the orientation of an anatomical plane or planes, and orient a prosthetic component or components.

An IM tibial nail aiming guide for providing proximal and distal screw fixation in an intramedullary nailing (IMN) of a tibia includes an attachment that connects and disconnects easily from a jig's proximal handle. Specifically, the IM tibial nail aiming guide functions as an aiming guide for accurate fixation of all the respective proximal and distal screw holes in a tibial nail. The IM tibial nail aiming guide has a length and angle that are adjustable, affording the ability to use this IM tibial nail aiming guide with any tibial nail. This IM tibial nail aiming guide is made of radiolucent material that allows for a confirmatory fluoroscopic imaging to verify that both the proximal and distal screws are fixated appropriately. The IM tibial nail aiming guide permits a more accurate, safe, versatile, and efficient approach to tibial IMN.

The application is directed to devices and methods where one or more magnetic or magnetizable implants provides therapeutic benefits to a patient. The implant may be useful for expanding the range of motion of joints or dynamically providing different responses to changing conditions in the body where the implant is placed. An electromagnet is placed on or in a bone on one side of a joint, and another electromagnet or magnetically active material is placed on or in a bone on the opposing side of the joint. The electromagnet may be continuously energized to relieve pressure in the joint space, or may, be energized in response to forces applied to the joint.

Systems and methods for joint replacement are provided. The systems and methods include a surgical orientation device and at least one orthopedic fixture. The surgical orientation device and orthopedic fixtures can be used to locate the orientation of an axis in the body, to adjust an orientation of a cutting plane or planes along a bony surface, to distract a joint, or to otherwise assist in an orthopedic procedure or procedures.

A three-dimensional (3-D) orthopedic drill guide device for accommodating a bone drill during an orthopedic surgery is disclosed. By establishing two specific angles in relation to the bone fascia, the device acts as a guide for bone drilling locations. In one specific instance, it is an optimal 3-D drill guide for the direction and Gamma angle (resulting from the devices Alpha and Beta angles of the device) of a drill hole in a femoral bone when used to replace an injured anterior cruciate ligament (ACL).

An assembly includes a catheter that has an insemination lumen for injecting sperm into a uterus. The insemination lumen includes two branches (sub-lumens), one directed toward a left ostium and the other directed to a right ostium of fallopian tubes.

The subject matter includes systems, methods, and prosthetic devices for joint reconstruction surgery. A computer-assisted intraoperating planning method can include accessing a first medical image providing a first view of a joint within a surgical site as well as receiving selection of a first component of a modular prosthetic device implanted in the first bone of the joint. The method continues by displaying a graphical representation of the first component of the modular prosthetic device overlaid on the first medical image, and updating a graphical representation of the first component based on receiving positioning inputs representative of an implant location of the first component relative to landmarks on the first bone visible within the first medical image. The method concludes by presenting a selection interface enabling visualization of additional components of the modular prosthetic device virtually connected to the first component and overlaid on the first medical image.

Systems and methods may be used to perform robot-aided surgery. A system may include a robotic controller to monitor a position and orientation of an end effector coupled to an end of a robotic arm. The robotic controller may apply a force to a bone using the end effector, such as via a soft tissue balancing component. The robotic controller may determine soft tissue balance using information from a tracking system, such as a position of a first tracker affixed to the bone. The soft tissue balance may be output, such as to a display device.
