  • Patent number: 11045209
    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: 11033395
    Abstract: An insert is advanced and at least partially secured into a prosthetic device configured for use in a joint. The prosthetic device includes a shell with a cavity defined by an interior surface. The interior surface includes first and second portions that share an edge and that abut an edge of the interior surface. The first portion includes a partially spherical surface while the second portion is a partially cylindrical shape. A maximum radius of the second portion is larger than a radius of the first portion. A center defining the maximum radius of the second portion is offset from a center defining the radius of the first portion. The geometry of the interior surface allows the insert to be advanced into the shell in a single orientation. When advanced sufficiently into the shell, the insert is rotated to constrain the insert within the shell.

  • Patent number: 10912591
    Abstract: An anterior cervical plate system is provided. The cervical plate includes a retention ring with a deflectable flange that is upwardly spaced from the top surface of the ring and configured to prevent an inserted bone fastener from backing out of the plate. The plate includes a locking pin having a camming surface and a blocking surface. When the camming surface is moved into position adjacent to the flange, the flange is free to flex out of the way of a bone screw being inserted into or removed from the plate. When the blocking surface is positioned adjacent to the flange, outward deflection of the flange is prevented to retain the bone screw inside the plate. The locking pin is rotated through a camming surface to bring a blocking surface against the flange deflecting the flange onto the head of the bone screw.

  • Patent number: 10912571
    Abstract: A smooth mating surface model defining a mating surface of a customized arthroplasty jig is generated. For example, sagittal slices of a volumetric image of a patient bone are segmented with segmentation splines. An anatomically accurate model of the patient bone is generated from the segmentation splines. The anatomically accurate model includes anatomically accurate segmentation splines. The anatomically accurate segmentation splines are transformed into mating surface contours. Any inadequate segments of the mating surface contours are modified to obtain modified mating surface contours. A mating surface model of the patient bone is generated based on the mating surface contours and the modified mating surface contours. Three-dimensional cross-sections of the mating surface model are smoothed to generate the smooth mating surface model.
