    Abstract: There is provided a tracing platform configured to rigidly attach to an anatomy of a patient that has at least one surface configured to provide a defined path (represented by path definition data) for tracing by a surgical instrument. An intra-operative computing unit receives pose data for the instrument when tracing the path and calculates a location of the defined path using the pose data and the path definition data. A change in location may be determined from pose data of different traces. Tracing the defined path generates a plurality of pose data which may increase accuracy of the location calculations. Redundant trace data may be received to eliminate bias. A geometric feature (e.g. V-groove), shape and/or magnetic properties of the platform may assist with tracing. The platform may rigidly attach to a bone using at least one of spikes, a bone screw, a cerclage wire, and a bone clamp.

  • Patent number: 11229485
    Abstract: Aspects of the disclosure may involve a method of generating resection plane data for use in planning an arthroplasty procedure on a patient bone. The method may include: obtaining patient data associated with at least a portion of the patient bone, the patient data captured using a medical imaging machine; generating a three-dimensional patient bone model from the patient data, the patient bone model including a polygonal surface mesh; identifying a location of a posterior point on the polygonal surface mesh; creating a three-dimensional shape centered at or near the location; identifying a most posterior vertex of all vertices of the polygonal surface mesh that may be enclosed by the three-dimensional shape; using the most posterior vertex as a factor for determining a posterior resection depth; and generating resection data using the posterior resection depth, the resection data configured to be utilized by a navigation system during the arthroplasty procedure.

  • Patent number: 11224448
    Abstract: A method and system for performing corrective surgery for pediatric or adult acquired flatfoot deformity (“AAFD”), namely, minimally invasive bone extra-articular reconstruction. The method and system comprises attaching a cutting guide to the bone to be operated wherein the cutting guide comprises two or more diverging K-wire channels and a slit configured to guide a burr used by a surgeon to perform osteotomy through the slit. Through the use of the cutting guide, the surgical procedure is simpler and reproducible. Patients will experience a quicker recovery, less pain, less operating room time, less narcotic use, and a better cosmetic result from smaller incisions. The present invention may also be applicable to intra-articular applications.

  • Patent number: 11207134
    Abstract: The surgery of revision knee arthroplasty is complex one for both of one and two stages for constraint and hinged implants. The inventor create a method and device to overcome the difficulties of this surgery as determining the size of the revision prosthesis and position of it on the bone after cut and replacement of the failed primary prosthesis. This method enable the surgeons to overcome the abnormalities, distortions and artifacts on bone surface which resulted from the CT scan due to the primary implant. It enables the surgeons to detect the size and position of the implant, also uses land marks on bone surface to design and product the device which use to perform the bone cutting. The device enables the surgeon to determine and guiding the bone cuts below the cement plane in case of cemented implants. Also guiding to the bone cuts below the implant surface in case of cement-less implants.

  • Patent number: 11166663
    Abstract: A device for preparing a femur of a patient for receipt of a knee implant in both extension and flexion relative to a resected tibia plateau based on applying tension to medial and lateral collateral ligaments of said patient, comprising a tibial baseplate, a tensioner, the tensioner comprising a tensioner body having a tensioner portion, the tensioner portion affixed to the tibial baseplate, and an expander arm comprising an elongated body portion, a superior side of the elongated body portion having a spiked tip adjacent a posterior end thereof. The spiked tip interacts with an intracondylar notch under tension. The expander arm is operatively connected to the tensioner body via the tensioner portion, the tensioner portion configured for use in selectively raising and lowering the expander arm relative to the tibial baseplate to apply tension to the medial and lateral collateral ligaments in extension or flexion.

  • Patent number: 11166767
    Abstract: Alignment precision technology, in which a system accesses image data of a bone to which a reference marker array is fixed. The system generates a three-dimensional representation of the bone and the reference markers, defines a coordinate system for the three-dimensional representation, and determines locations of the reference markers relative to the coordinate system. The system accesses intra-operative image data that includes the bone and a mobile marker array that is attached to an instrument used in a surgical procedure. The system co-registers the intra-operative image data with the three-dimensional representation by matching the reference markers included in the intra-operative image data to the locations of the reference markers. The system determines locations of the mobile markers in the co-registered image and determines a three-dimensional spatial position and orientation of the instrument relative to the bone.

  • Patent number: 11147567
    Abstract: Instrumentation sets and methods for preparing and implanting an osteochondral allograft to a bone lesion. Instrumentation sets include a pair of guide blocks, a recipient guide block and an allograft guide block, for preparing a cavity at the bone lesion matched by a similarly sized and shaped allograft. Guide blocks provide simple and direct techniques for preparing a matching cavity, formed at the bone lesion, to a bone implant, to be secured within the cavity. Methods include use of the instrumentation to restore bone surfaces for any number of sites using any allograft source. In some cases, the bone lesion is in a humeral head and the allograft source is a talus.

  • Patent number: 11147626
    Abstract: Systems and methods facilitate the planning and performance of hip and other surgeries. A computer model of a hip may be generated and displayed. A template of a hip component that replaces a native portion of the hip may be superimposed on the model. Changes in leg length, offset, or anterior-posterior (AP) position as well as a virtual distance between a landmark on the model and a location on the template may be determined. During surgery, a physical distance corresponding to the virtual distance may be obtained. The template may be moved relative to the model to match the physical distance, and new change values in leg length, offset, or anterior-posterior (AP) position may be determined. The new change values may be evaluated, and the surgery may proceed, or the process may be repeated using templates corresponding to alternative components.
