  • Publication number: 20180253847
    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.

  • Publication number: 20180177553
    Abstract: In accordance with one or more embodiments herein, a system for optimizing an implant position in an anatomical joint of a patient is provided. The system comprises a storage media and a processor which is configured to: receive medical image data representing a three dimensional image of the joint from the storage media; obtain a three dimensional virtual model of the joint which is based on the received medical image data; identify damage in the joint based on the received medical image data and/or the three dimensional virtual model of the joint; select a suitable implant template based on the identified damage; and position the selected implant template in the three dimensional virtual model of the joint. The processor is configured to position the implant template by: placing the implant template so that at least a major part of the damage is covered; and optimizing the tilt of the implant axis in order to minimize the total penetration into the bone.

  • Publication number: 20170172744
    Abstract: A surgical joint implant has a cap in the form of at least two intersecting circles of the same diameter having an articular outer surface and an inner surface for bone adhesion. At the center of each circle a peg, for bone insertion into a hole of a nominal diameter, extends. One peg is slightly larger than said nominal diameter, to achieve an interference fit and the other peg is slightly thinner, to achieve a slide fit. A tubular drill rig open at both ends and having an interior circumference corresponding to the outer shape of the implant, can be mounted over the bone surface to be repaired. It accommodates a double drill for drilling, at the same time, a shallow hole of the diameter of the intersecting circle and a deeper narrow hole at the center of the circle of said nominal diameter.

  • Publication number: 20170156890
    Abstract: A design method for design of a rig is presented. The rig comprises a hollow tubular shell, and the interior of said shell defines at least first and second intersecting cylinders. The design method comprises identifying a damage area, presenting a 3D view of identified damage area and generating a 3D model of a virtual rig. The generating comprises virtually placing in 3D view a shape covering or partly covering damage area, and creating, based on the position of the virtually placed shape, a position of hollow tubular rig shell of the virtual rig. The method further comprises selecting the at least first and second intersecting cylinders of the virtual rig, based on the size and form of the virtually placed shape, and creating a positioning surface of the virtual rig which is a bone and/or cartilage-engaging end of hollow tubular shell. The positioning surface is adapted to follow the surface surrounding the virtually placed shape when the virtual rig is placed in a virtual model of the joint.
