  • Patent number: 10736755
    Abstract: A workstation having a pair of posts on either side of a clamping plate where a donor bone may be placed on sequentially cut in three separate cutting paths. Cutting gates are attached to the posts and used to provide cutting paths that can be precisely oriented with respect to the meniscus of the donor bone part using visual alignment without any manual measurements. The graft is affixed to a machining clamp and shaved to appropriately shape the sides and form a radius on the bottom of the graft. A tibia is then prepared by using a drill guide to form a pilot hole and then to drill out a large hole for the graft. The drilled hole is expanded and shaped using a rod guide and chisel and then a rasp. The shaped graft may then be implanted into the shaped hole and sutured in place.

    Abstract: An instrument for establishing orientation of a pelvic prosthesis comprises a tripod having an angularly adjustable guide rod on it. The tips of the legs define a plane, and the guide rod is set by the surgeon to a defined orientation with respect to this plane on the basis of preoperative studies. In use, two of the legs of the instrument are positioned by the surgeon at defined anatomical locations on the pelvis (e.g., a point in the region of the posterior/inferior acetabulum and a point on the anterior superior iliac spine). The third leg then lands on the pelvis at a point determined by the position of the first two points, as well as by the separations between the third leg and the other two legs. The position of the guide rod then defines with respect to the actual pelvis the direction for insertion of a prosthesis.

  • Patent number: 10292717
    Abstract: Systems and methods to provide patient-specific cutting blocks that allow for bone resurfacing procedures, such as milling or burring, with simplified devices. A computer assisted surgical cutting block is produced having a surface region that matches with the surface region of a patient's bone to be altered. A cutting tool may be provided having a contoured bone mating surface and a contoured and patient-specific shaped cutting guide surface located in a plane above the bone mating surface. One or more channels are provided in the cutting block, and as the surgeon moves the cutting tool (a milling or burring, for example) in the channels, the tool cuts the bone both laterally along the surface of the bone and vertically into the bone according to the cutting guide surface and other preselected surface features of the cutting block.

  • Patent number: 10265081
    Abstract: A tibial cutting guide includes upper and lower portions having patient-matched surfaces. The upper portion defines resection slots for forming resections about the tibial eminence. The lower portion defines two pin slots for receiving alignment pins such that in use the position of the resection slots relative to the tibial eminence can be adjusted by sliding the cutting guide along the alignment pins placed in the tibia through the pin slots. The lower portion defines a resection slot for guiding a saw blade to form a horizontal plateau resection, and two pin holes for receiving fixation pins. A method includes positioning a patient-matched cutting guide on the proximal tibia; intra-operatively adjusting the position of the cutting guide in two degrees of freedom by sliding the cutting guide along fixation pins placed in the tibia; and resecting the tibia about the tibial eminence.

  • Patent number: 10242127
    Abstract: A method for making a surgical guide for bone harvesting identifying in a three-dimensional image of a bone one or more sensitive anatomic structures and a volume of bone suitable for being removed. The volume is delimited by a portion of an outer surface of the bone defining a perimeter and by a mantle extending from the perimeter inside of the bone. The method also includes designing the surgical guide which includes defining a guide surface including a work area delimited by guide walls. The method also includes angling at least one of the guide walls so that the guide wall includes a face that constitutes a geometrical extension of a portion of the mantle when the guide is rested on the outer surface of the bone such that the face includes at least one segment forming a predetermined angle with respect to the guide surface.
