A system and related methods for performing nerve detection during surgical access using ultrasound testing during surgery.

A method for the fluoroscopic registration in real time for placement of pedicle screws or the like during spinal surgery, comprising creating a lateral image in which a pedicle has appropriate anatomic contour and superior endplate, advancing a pin into the pedicle starting in the posterior cortex and moved far enough into the pedicle to anchor the pin, rotating the fluoroscopy to obtain an AP image of the pedicle which is moved to render the pin to be neutral in a cephalad to candad direction, and positioning a pedicle screw in the pedicle following 2D contour mapping generated by manual or automated templating.

An augmented reality guidance system for guiding surgical operations on an articulating portion of a bone includes a tracking element to be attached to the articulating portion and-having a surface bearing against the portion that is custom-designed from a virtual model , and a three-dimensional reference mark ; a probe with a three-dimensional reference mark for probing at least three regions of a portion apart from the cartilage area; a camera for displaying and tracking the reference marks ; and a processing system for processing virtual bone model data and real-time image data from the camera to determine the position and relative direction of the tracking element and probe, to display on a display device , a three-dimensional virtual representation of a geometric datum relating to the bone model having position and direction determined by the position and direction of the tracking device and corrected after probing.

A system includes a cartridge having an elongate body extending from a first end to a second end and having a top side and a bottom side. The cartridge defines a first hole adjacent to the first end that extends through the cartridge from the bottom side to the top side. The top side of the cartridge defines a pair of parallel slots that extend perpendicular with respect to a longitudinal axis of the cartridge. Each slot of the pair of parallel slots is equidistant from a central axis defined by the first hole.

A number of improvements are provided relating to computer aided surgery utilizing an on tool tracking system. The various improvements relate generally to both the methods used during computer aided surgery and the devices used during such procedures. Other improvements relate to the structure of the tools used during a procedure and how the tools can be controlled using the OTT device. Still other improvements relate to methods of providing feedback during a procedure to improve either the efficiency or quality, or both, for a procedure including the rate of and type of data processed depending upon a CAS mode.

Systems and methods are disclosed in which changes in the position and/or orientation of an anatomical structure or of a surgical tool can be measured quantitatively during surgery. In some embodiments, the systems and methods disclosed herein can make use of inertial motion sensors to determine a position or orientation of an instrument or anatomy at different times and to calculate changes between different positions or orientations. In other embodiments, such sensors can be utilized in conjunction with imaging devices to correlate sensor position with anatomical landmarks, thereby permitting determination of absolute angular orientation of a landmark. Such systems and methods can facilitate real-time tracking of progress during a variety of procedures, including, e.g., spinal deformity correction, etc.

Various embodiments of an emitter-aligned surgical guide and methods of use are disclosed. The emitter-aligned surgical guide includes a body extending between a first surface and a second surface. The body defines at least one hole extending from the first surface to the second surface. At least one alignment jig is coupled to the second surface. The at least one alignment jig includes a jig arm extending from a first end coupled to the second surface of the body to a second end and an emitter support configured to couple an emitter device to the at least one alignment jig in a predetermined position relative to the body.

A surgical guide and methods of using the surgical guide are disclosed. The surgical guide includes a body having a first side and a second side. An adhesive material is disposed over at least a portion of the first side. A radiopaque guide element coupled to a second side of the body and an incision guard defines an opening extending from the first side to the second side of the body. The incision guard is sized and configured to receive a surgical instrument therethrough such that the incision guard prevents contact between the surgical instrument and a portion of a surgical site adjacent to the opening.

A system and related methods for performing nerve detection during surgical access using ultrasound testing during surgery.

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.
