    Abstract: A method for assisting subchondral injection comprising creating a model of bone and soft tissue of a patient. At least one void is modeled in the bone from the model of bone and soft tissue. An injection site is identified from the model of bone and soft tissue and modeling of the at least one void. Data is output for guiding at least in the locating of the injection site and drilling of the bone to reach the void. A patient-specific jig for subchondral injection may be created based on the injection site location.

    Abstract: A patient specific instrument (PSI) surgical guide and method for producing same is described. The method includes: obtaining imagery of at least a portion of a patient, and determining one or more surgical targets in the tissue; planning at least a trajectory of the surgical procedure based on a determined surgical target within the tissue; performing segmentation of the imagery; creating a three-dimensional model of the PSI surgical guide, the PSI surgical guide being customized in size and shape and configured to fit on the specific patient. The PSI surgical guide is then produced to correspond to the modeled PSI surgical guide. The PSI surgical guide has a guide element positioned and oriented to guide a surgical implement along the planned trajectory toward the determined surgical target in the tissue.

    Abstract: Examples of robotically controlled planar cutting systems and methods for controlling cutting systems to prepare bone tissue in surgical procedures, are generally described herein. Applicable surgical procedures for the robotically controlled cutting systems and methods include procedures involving the preparation (e.g., removal, surfacing) of bone tissue, such as is performed in knee arthroplasties.In an example, a robotically controlled planar cutting system can include a housing, a cutting element disposed in the housing, and a cutting control mechanism in communication with a robotic controller to control operation of the cutting element to machine a planar surface. The cutting element can be exposed and retracted relative to the housing and can include a plurality of cutting implements arranged to machine the planar surface.

    Abstract: A method for determining a mechanical axis of a tibia using a tibial digitizer is disclosed. The method includes: determining an upper reference point on a tibial plateau corresponding to an entry point of the mechanical axis; fastening an upper mounting end of the tibial digitizer to the tibial plateau at the upper reference point; and fastening a lower mounting end of the tibial digitizer to medial and lateral malleoli of the ankle, by inwardly displacing opposed caliper arms of a self-centering malleoli engaging mechanism toward each other in a common plane until the caliper arms abut the malleoli. A lower reference point located at a midpoint between the medial and lateral malleoli is then determined by identifying a corresponding midpoint between the caliper arms when they are clamped onto the medial and lateral malleoli.

    Abstract: The disclosed device for verifying a hip-knee-ankle angle includes a mounting base having a planar abutting surface adapted for direct abutting against a resected surface on a distal femur, and a first inertial sensor in communication with a computer assisted surgery (CAS) system to determine an orientation of the mounting base and to digitize a mechanical axis of the femur. A visual alignment guide element is pivotably mounted to the mounting base such that the angular position of the visual alignment guide element is adjustable so as to be visually aligned with a mechanical axis of a tibia. A difference between orientations of the mounting base and the visual alignment guide is calculated by the computer assisted surgery system to determine the hip-knee-ankle angle. The visual alignment guide may include a second inertial sensor and/or a laser emitting element.

    Abstract: A system for determining a position and an orientation of a bone of an anatomical feature includes a trackable reference device having a surgical pin at a first position being attachable to the bone. A wearable attachment attached to the trackable reference device is configured to be mounted about the outer-skin surface of the anatomical feature. A distance sensor mounted to the trackable reference device at a second position is operable to determine a distance measurement of the second position of the trackable reference device from the bone. Reference markers are fixedly mounted to the trackable reference device. A position sensing device registers position and orientation readings of the reference markers in a reference coordinate system. A processing unit determines the position and the orientation of the bone in the reference coordinate system using the position and orientation readings and the distance measurement.

    Abstract: Systems and methods for determining position and orientation of a bone of an anatomical feature are described. These include the use of a wearable holder configured to be mounted about an outer-skin surface of the anatomical feature, such that the anatomical feature and the bone are positioned in fixed relation with respect to the wearable holder when the wearable holder is mounted about the anatomical feature. Reference marker arrays are fixedly mounted to the wearable holder, each being positioned on the wearable holder to identify a landmark of the bone within the wearable holder when the wearable holder is mounted to the anatomical feature. The position and orientation of the reference markers are trackable to determine position and orientation of the wearable holder in a reference coordinate system, thereby enabling position and orientation of the landmarks on the bone to be determined.
