Abstract: Disclosed are systems and methods for a computerized framework that provides novel mechanisms for arthroscopic applications using real-time blood flow information. The disclosed framework operates by determining a real-time (or near real-time or substantially simultaneous) visualization of blood vessels or perfusion within anatomical structures during intraoperative procedures, and leveraging this determined information for the performance of an arthroscopic procedure. The disclosed framework can enable an arthroscopic camera to see blood flow and perfusion in tissues in real-time, which allows for differentiation of various parts of the anatomy that may otherwise be undetectable.

Abstract: A targeting system is disclosed. In use, the targeting system is configured to target (e.g., aim, locate, etc.) a fastener opening in a bone plate, more particularly, a variable angled fastener opening formed in a periphery of a periprosthetic bone plate. In one embodiment, the targeting system includes an alignment guide including a plurality of combo-slots for targeting a plurality of openings formed in the periprosthetic bone plate. In addition, the targeting system includes a plug configured to be positioned within the combo-slots formed in the alignment guide. In use, positioning the plug into the combo-slot formed in the alignment guide transforms the combo-slot into a substantially circular hole or opening with a predefined trajectory aligned with one of the variable angled openings formed in the periphery of the periprosthetic bone plate thereby defining a trajectory from the alignment guide to the variable angled opening.

Abstract: Embodiments of negative pressure wound therapy systems and methods for operating the systems are disclosed. In one embodiment, a negative pressure source can provide negative pressure via a fluid flow path to a wound dressing comprising a stabilizing structure. The stabilizing structure can be inserted into a wound and collapse upon application of negative pressure to the wound when the stabilizing structure is positioned in the wound. A controller can in turn determine a measure of collapse of the stabilizing structure from a pressure in the fluid flow path while the negative pressure source maintains a magnitude of the pressure in the fluid flow path within a negative pressure range. The controller can output an indication responsive to the measure of collapse.

Abstract: Provided are methods for repairing a wound or inducing the proliferative phase of a wound comprising administering a composition comprising a protease mixture comprising collagenases and a neutral protease to the wound in an amount effective for repair of wound tissue or for inducing the proliferative phase in the wound.

Abstract: Various embodiments disclosed herein relate to improved systems and methods for performing computer-aided surgical navigation using augmented reality. A tracking device having one or more optically detectable points is mounted to a patient via surgical hardware. The detectable points are identified by a sensor. One or more augmented reality marker assemblies that each have an augmented reality fiducial marker or symbol are also attached to the tracking device. A computer system generates augmented reality information and transmits it to a display screen, such as a near-eye augmented reality device, for display thereon. The near-eye augmented reality device also has an image capture device capable of capturing the augmented reality symbols, and thereby determining a three-dimensional orientation associated with the tracking device, augmented reality markers, and a user wearing the near-eye reality device.

Abstract: Systems and methods for power conservation of embedded sensors are provided. In some embodiments, at least one sensor positioned within an orthopedic implant operably senses a triggering event of a patient. A sensor signal representative of the triggering event may be sent from a controller to a processor, wherein the controller is operatively connected to the at least one sensor. A command signal may then be sent from the processor to control operation of the at least one sensor.

Abstract: Certain embodiments of the invention provide plates for treating periarticular fractures or other non-full body weight bearing applications that combine polyaxial fixation with a low profile and enhanced contouring that more closely conforms to bone. Such plates can be designed to achieve buttressing effect and/or to be used in a reinforcement mode. Other features can be combined with these. Such plates can be created for use on bone sites such as on a tibia, fibula, metatarsal, calcaneous, other foot bone, humerus, radius, ulna, spinal, maxillofacial, as well as sites on other bones.

Abstract: A collinear reduction clamp including a compression rod, an arm, and an advancing mechanism for moving the compression rod relative to the arm. In some examples, the rod may include a cannulated bore to enable a bone screw to be inserted therein. The rod may also include a cap. The cap including a bone screw washer. In use, a bone screw can be inserted through the cannulated bore of the rod, the bone screw passing through the washer thereby coupling the washer to the bone screw thereby enabling both the bone screw and the washer to be inserted into the patient's bone directly at the compression site. In some examples, the cannulated bore may be used in combination with first and second tubes and a guidewire to enable a cannulated bone screw to be inserted therein. In some examples, the arm may be configured as a length adjusting arm.

Abstract: Methods, non-transitory computer readable media, and surgical computing devices are disclosed herein for creating a three-dimensional (3D) model based on a plurality of received two-dimensional (2D) medical images containing patient anatomy and a tracking fiducial. Once the 2D images are received, a determination is made regarding any potential processing steps required to put the images into a standard view. Once the images are processed, a user may modify or adjust various factors. Using the size and orientation of the tracking fiducial a 3D virtual model is created based on a repository of known patient data, such as a bone atlas. The 3D virtual model can then be output to a display device and optionally used to facilitate a surgical procedure. The 3D virtual model of patient anatomy can advantageously be generated more quickly and using fewer resources with this technology.
