  • Patent number: 11819280
    Abstract: A model production device generates one or more contact bodies of a patient-specific surgical instrument model based on a parameterized model of a patient's bone. The parameterized model includes a predetermined number of polygons each having a predetermined position relative to the patient's anatomy. The parameterized model may be generated based on a three-dimensional model that was generated based on multiple images of the patient's bone. The model production device adds parametric fixed geometry to the patient-specific surgical instrument model based on the parameterized model and subtracts the three-dimensional model of the patient's bone from the patient-specific surgical instrument model. Each contacting body may be positioned at a high-confidence part of the parametric model, and the parametric fixed geometry may be positioned at a low-confidence part. A patient-specific surgical instrument may be manufactured based on the patient-specific surgical instrument model.

    Abstract: Disclosed herein are systems and methods for bone preparation with designed areas having accurate tolerance profiles to enable improved initial fixation and stability for cementless implants and to improve long-term bone ingrowth/ongrowth to an implant. A method of preparing a bone surface to receive a prosthetic implant thereon having an articular surface and a bone contacting surface includes resecting the bone surface at a first location to create a first resected region having a first tolerance profile with a first cross-section, resecting the bone surface at a second location to create a second resected region having a second tolerance profile with a second cross-section less dense than the first cross-section, and contacting the bone contacting surface of the prosthetic implant with the first resected region.

    Abstract: The disclosure includes methods and systems for making orthopedic connections where there is unique adjustability to the connection. Illustratively, one embodiment provides a connecting assembly for connecting a plurality of orthopedic components. Such connecting assemblies can include a first orthopedic component that provides a female bore. Additionally the assembly can include a second orthopedic component that can be or include a male-type connecting member that is positionable in the bore of the first orthopedic component. In one preferred form, the male-type connecting member will be a quasi-spherical member. The quasi-spherical member can include a textured outer surface, e.g., for contacting one or more walls or surfaces in the bore in a fashion that removeably locks or helps to removeably lock or fix the quasi-spherical member in the bore.

  • Patent number: 10327848
    Abstract: A data processing method, performed by a computer, for determining implant positions of two implant components relative to two bones, wherein each of the implant components is to be attached to one of the bones such that the implant components form a joint between the bones, and wherein an implant position is a relative position between the implant component and the corresponding bone, said method comprising the steps of: a) acquiring a set of target poses, wherein a target pose represents a relative position to be achieved between the two bones; b) calculating a set of virtual poses for a pair of virtual test implant positions, wherein the set of virtual poses comprises one virtual pose for each of the target poses and wherein a virtual pose represents a relative position between the two bones if the virtual test implant positions were applied as the implant positions; c) calculating a pose deviation value for each of the target poses, wherein a pose deviation value represents the difference between a target

  • Patent number: 10052209
    Abstract: A polyaxial ankle joint replacement implant has a dual bearing component situated between a tibia attachment component and a talus attachment component. The dual bearing component includes a plate, a superior bearing bonded to the plate and providing translation with the tibia attachment component, and an inferior bearing providing translation with the talus attachment component. The tibia attachment component has peripheral transversely extending flanges that limit movement relative to the superior bearing and vice versa. The plate has a flange on its inferior surface that receives an opening in the inferior bearing, the size of the opening determining an amount of lateral translation. The plate also has unobstructed posterior and/or anterior ends that permit removal and replacement of the inferior bearing post-operative. This allows change from a mobile to fixed bearing (and vice versa), as well as a change in amount of degrees of translation.
