    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.

    Abstract: A computer-assisted surgery system comprises a calibrating instrument adapted to be applied to a pelvis in a known manner, and a surgical instrument. A computer-assisted processor unit operating a surgical assistance procedure and comprises at least one portable inertial sensor unit configured to be connected to the at least one calibrating instrument and the at least one surgical instrument, the portable inertial sensor unit outputting readings representative of its orientation. A geometrical relation data module provides a geometrical relation data between the orientation of the portable inertial sensor unit, of the calibrating instrument and of the surgical instrument. A coordinate system module sets a coordinate system of the pelvis in which an anterior-posterior axis of the pelvis is generally in a direction of gravity, and in which a medio-lateral axis of the pelvis is obtained from readings of the at least one portable inertial sensor unit on the calibrating instrument using the geometrical relation data therebetween. A tracking module tracks movements of the at least one surgical instrument relative to the coordinate system using readings from the inertial sensor unit on the surgical instrument using the geometrical relation data therebetween, and calculates navigation data for the movements, the navigation data relating the orientation of the surgical instrument to the orientation of the pelvis. An interface outputs the navigation data.

    Abstract: A system for sizing an implant for a patient pre-operatively comprises a processor unit. A non-transitory computer-readable memory may be communicatively coupled to the processing unit and comprising computer-readable program instructions executable by the processing unit for obtaining at least one radiographic patient image of at least one patient bone with a scale marker relative to the bone, the scale marker having a known geometry, setting a scale of the at least one radiographic patient image using the known geometry of the scale marker, generating a three-dimensional bone model representative of the at least one patient bone using the at least one radiographic patient image and the scale, identifying an implant size and/or an implant model using implant models and dimensions of the three-dimensional bone model based on said scale, and outputting the implant size and/or the implant model for the patient.

    Abstract: Embodiments of a system and method for digitizing locations within a coordinate system are generally described herein. A device may include a sleeve including a sleeve tracking marker and a tracked probe portion including an array of tracking markers and a probe tip. Movement of the probe tip relative to the sleeve between at least a first position and a second position may be monitored by tracking the sleeve tracking marker relative to at least one tracking marker of the array of tracking markers.

    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 reference jig comprises a base adapted to be secured to a distal end of a bone. An adjustment mechanism has a bracket, one or more rotational joints operatively mounting the bracket to the base, whereby the bracket is rotatable in two or more rotational degrees of freedom relative to the base, and one or more translational joints. A landmark alignment unit is operatively connectable to the bracket by the at least one translational joint, the landmark alignment unit having a bone alignment component configured to be aligned with at least one bone landmark.
