Osteotomy Jig Or Fixture Patents (Class 606/87)
  • Patent number: 11166767
    Abstract: Alignment precision technology, in which a system accesses image data of a bone to which a reference marker array is fixed. The system generates a three-dimensional representation of the bone and the reference markers, defines a coordinate system for the three-dimensional representation, and determines locations of the reference markers relative to the coordinate system. The system accesses intra-operative image data that includes the bone and a mobile marker array that is attached to an instrument used in a surgical procedure. The system co-registers the intra-operative image data with the three-dimensional representation by matching the reference markers included in the intra-operative image data to the locations of the reference markers. The system determines locations of the mobile markers in the co-registered image and determines a three-dimensional spatial position and orientation of the instrument relative to the bone.

    Abstract: Instrumentation sets and methods for preparing and implanting an osteochondral allograft to a bone lesion. Instrumentation sets include a pair of guide blocks, a recipient guide block and an allograft guide block, for preparing a cavity at the bone lesion matched by a similarly sized and shaped allograft. Guide blocks provide simple and direct techniques for preparing a matching cavity, formed at the bone lesion, to a bone implant, to be secured within the cavity. Methods include use of the instrumentation to restore bone surfaces for any number of sites using any allograft source. In some cases, the bone lesion is in a humeral head and the allograft source is a talus.

  • Patent number: 11147626
    Abstract: Systems and methods facilitate the planning and performance of hip and other surgeries. A computer model of a hip may be generated and displayed. A template of a hip component that replaces a native portion of the hip may be superimposed on the model. Changes in leg length, offset, or anterior-posterior (AP) position as well as a virtual distance between a landmark on the model and a location on the template may be determined. During surgery, a physical distance corresponding to the virtual distance may be obtained. The template may be moved relative to the model to match the physical distance, and new change values in leg length, offset, or anterior-posterior (AP) position may be determined. The new change values may be evaluated, and the surgery may proceed, or the process may be repeated using templates corresponding to alternative components.

    Abstract: A method acquires a reconstructed tomographic volume image of anatomy of a patient and constructs a primary axis for a bone of interest in the imaged anatomy. The method forms a sectioned image of the bone in the volume image according to a first plane that is defined to extend along the bone and to extend through two or more articular surfaces. A primary axis for the bone is estimated, wherein the primary axis is midway between outer edges of the bone image that intersect the first sectioning plane. The bone is sectioned in the volume image by a second plane that is orthogonal to the first plane and that extends through the estimated primary axis. The method recalculates the position of the constructed primary axis according to the sectioning of the bone by the second plane. The recalculated constructed primary axis for the bone of interest is displayed.

  • Patent number: 10765534
    Abstract: A method of implanting a humeral component includes accessing a humerus and resecting a head portion of the humerus to form a resected surface. The method further includes selecting a first combination sizer and guide device having an outer surface sized complementary to a desired implant head size, positioning the selected first combination sizer and guide device on the resected surface, guiding placement of a guide pin in the humerus with the first combination sizer and guide device, guiding a reamer with the placed guide pin to form a reamed cavity in the humerus, positioning an anchoring portion of a humeral implant base portion in the reamed cavity, positioning the first combination sizer and guide device on the base portion, removing the first combination sizer and guide device from the base portion, and positioning an implant head on the base portion.

  • 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.

  • Patent number: 10722310
    Abstract: Systems and methods are disclosed herein. According to one example, the method can comprise imaging a target location of an anatomy of a patient to collect image data regarding at least one of a bone size, a bone orientation and a bone shape of the patient, displaying based upon the collected image data one or more patient-specific characteristics of the anatomy of the patient, and determining one or more of a size, a shape and an orientation for at least one bone graft based at least in part upon the one or more patient-specific characteristics of the anatomy of the patient. The method can convert the one or more patient-specific characteristics of the anatomy of the patient to a setting for a cutting instrument.

  • Patent number: 10672124
    Abstract: A system for creating decision support material indicating damage to an anatomical joint of a patient. The system is configured to: i) receive a series of radiology images of at least a part of the anatomical joint; ii) obtain a three-dimensional image representation of the at least part of the anatomical joint; iii) identify tissue parts of the anatomical joint using image analysis; iv) determine damage to the anatomical joint by analyzing said image representation; v) mark damage to the anatomical joint in the obtained three-dimensional image representation; and vi) generate decision support material. The analysis comprises: detecting an irregular shape of a contour of a tissue part; and/or detecting that the intensity in an area within or adjacent to bone and/or cartilage parts differs from a predetermined value; and/or comparing at least one identified tissue part with a template representing a predefined damage pattern for an anatomical joint.
