  • Patent number: 10398450
    Abstract: Methods for resecting a portion of a knee joint are described herein. While the described methods can comprise any suitable step, in some implementations, the methods include cutting a cylindrically-shaped hole in a portion of the knee joint selected from at least one of a distal portion of a femur and a proximal portion of a tibia in the knee joint; and using a depth of the cylindrically-shaped hole as a reference point to resect bone around the cylindrically-shaped hole to a depth substantially matching the depth of the cylindrically-shaped hole. Other implementations are described.

  • Patent number: 10194919
    Abstract: A dynamic trialing method generally allows a surgeon to perform a preliminary bone resection on the distal femur according to a curved or planar resection profile. With the curved resection profile, the distal-posterior femoral condyles may act as a femoral trial component after the preliminary bone resection. This may eliminate the need for a separate femoral trial component, reducing the cost and complexity of surgery. With the planar resection profile, shims or skid-like inserts that correlate to the distal-posterior condyles of the final insert may be attached to the distal femur after the preliminary bone resection to facilitate intraoperative trialing. The method and related components may also provide the ability of a surgeon to perform iterative intraoperative kinematic analysis and gap balancing, providing the surgeon the ability to perform necessary ligament and/or other soft tissue releases and fine tune the final implant positions based on data acquired during the surgery.

  • Patent number: 9833244
    Abstract: Sensing technology methods related thereto for determining cut through of bone and a depth of penetration of a working portion of a surgical instrument (e.g., an oscillating saw blade in a cut). A first sensor outputs a first signal representative of a displacement of the cutting edge of the saw blade in the cut. A second sensor outputs a second signal representative of a force applied to the cutting edge of the saw blade. As such, monitoring the first and/or second sensor may allow for the saw to be stopped upon completion of a cut (e.g., when the saw passes completely through a medium to be cut or upon reaching a predetermined depth for the cut).

  • Patent number: 9826994
    Abstract: A system and method for aligning a guiding pin relative to a glenoid including a guiding pin insertion guide for orienting the guiding pin relative to the anatomic structure and an axis alignment device. The guiding pin insertion guide includes a base plate and a movable pin orientation device coupled to and extending from the base plate. The axis alignment device has a plurality of through holes that each define a different alignment axis. The guiding pin mates with one of the through holes to align the guiding pin at a patient-specific alignment axis, the guiding pin is then received within the guiding pin insertion guide when mated with the one of the through holes to align the guiding pin insertion guide along the patient-specific alignment axis relative to the base plate, and the guiding pin insertion guide is fixed to the base plate along the patient-specific alignment axis.

  • Patent number: 9814499
    Abstract: An intramedullary bone fixation device is provided with an elongate body having a longitudinal axis and an actuator to deploy at least one gripper to engage an inner surface of the intramedullary space to anchor the fixation device to the bone. Methods of repairing a fracture of a bone are also disclosed. One such method comprises inserting a fixation device into an intramedullary space of the bone to place at least a portion of the fixation device on one side of the fracture, providing rigidity across the fracture, and operating an actuator to deploy at least one gripper to engage an inner surface of the intramedullary space to anchor the fixation device to the bone. Various configurations allow a segmented device body to lock in the intramedullary space before and/or after fixation of the bone.

  • Patent number: 9782183
    Abstract: A surgical viewing system including an X-ray source, a screw placing surgical tool, a detector, a fiducial marker, and an image correction system. The X-ray source creates a beam of radiation, and the surgical tool is coupled thereto. The X-ray detector detects an image, the detected image resulting from receiving a portion of the radiation. There is at least one fiducial marker coupled to a part of the surgical tool, the fiducial marker being radiopaque and blocking a portion of the beam of radiation from the detector to produce a profile on the detected image. The surgical tool has an axis of rotation and the fiducial marker is axially symmetric to the axis of rotation. The image correction system takes the detected image and produces a corrected image by using a shape of the profile of the fiducial marker and/or a location of the profile of the fiducial marker.

  • Patent number: 9730708
    Abstract: A method, and devices for facilitating the method, for shoulder replacement surgery. The method entails establishing a mechanical support in a the anatomical neck plane of the proximal humeral head, fixing a jig to the mechanical support, where the jig supports a drill guide with its axis perpendicular to the anatomical neck plane, adjusting the drill guide it coincide with the axis of the humeral head, drilling a hole through the humeral head for insertion of a shaft which will support and rotate a reaming bit. The reaming bits used to resurface the humeral head and the glenoid fossa are inserted through the back of the patient, through a gap created between two easily separated muscles, rather than through a gap cut through the subscapularis muscle on the front of the joint. A suitable jig is provided to facilitate the method.
