  • Publication number: 20250082413
    Abstract: In another embodiment, a hip joint navigation jig is provided that includes an anatomical interface comprising a bone engagement portion. A registration jig is also provided that is coupled, e.g., removeably, with the anatomical interface. A rotatable member is provided for rotation about an axis that is not vertical when the jig is mounted to the bone adjacent to a hip joint and the registration jig is coupled with the anatomical interface. An anatomy engaging probe is coupled with the rotatable member for rotation about the axis and is translatable to enable the probe to be brought into contact with a plurality of anatomical landmarks during a procedure. An inertial sensor is coupled with the probe to indicate orientation related to the landmarks, the sensor being disposed in a different orientation relative to horizontal when the probe is in contact with the landmarks.

  • Publication number: 20250057658
    Abstract: The present disclosure includes examples of an implant system configured for targeted joint resurfacing in which only an area including the osteochondral defect is resected, wherein the area resected occupies an area smaller than an entire joint surface. The implant system can include a monolithic first implant with 3D printed metal and a second implant including a plastic portion overmolded onto a metal portion. The metal portion of the second implant also includes 3D printed metal. The first and/or second implants include solid metal portion(s) and porous metal portion(s). In an example, the first implant can be a femoral implant and the second implant can be a tibial implant. The first and second implants can be used on their own or in tandem.

  • Publication number: 20250017745
    Abstract: A hip joint navigation system is provided that includes a base having at least one channel disposed therethrough for receiving a pin for mounting the base to the pelvis. A mount feature is disposed on a top surface. A registration jig is configured to couple with the base and to engage anatomical landmarks. In some aspects, a patient specific jig system for hip replacement is provided including an engagement surface formed to closely mate to acetabular bone contours of a specific patient and a registration feature configured to be in a pre-determined orientation relative to an acetabulum the patient when the jig is coupled with acetabular bone contours of the specific patient. In other aspects, methods of using the systems are provided.

  • Publication number: 20240099731
    Abstract: Systems and methods for joint replacement are provided. The systems and methods can include a surgical orientation device and/or a reference sensor device. 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, to measure an angle, to orient a cutting guide, to orient a resection guide, to resect the femur, or to otherwise assist in an orthopedic procedure or procedures.

  • Publication number: 20230149185
    Abstract: 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.
