A system for customizing an implant is provided. The system includes a processor configured to: i) obtain one or more medical image stacks of a joint; ii) obtain a three-dimensional image representation of the joint based on at least one of said medical image stacks; iii) determine damage to the joint by analyzing said medical image stacks; iv) select an implant template from a predefined set of implant templates having predetermined types and sizes; v) generate a 3D model, in which the marked damage is visualized together with the selected implant template in a proposed position; vi) display the 3D model; vii) receive an approval for said selected implant template in said proposed position; and viii) determine the final shape and dimensions of a customized implant based on said selected implant template and said proposed position.

A system for determining and visualizing damage to an anatomical joint of a patient. The system is to: obtain a three dimensional image representation of an anatomical joint which is based on a medical image stack; determine damage to an anatomical structure in the anatomical joint by analyzing the medical image stack; mark damage to the anatomical structures in the obtained three dimensional image representation; obtain a 3D model based on the three dimensional image representation; and create a graphical user interface (GUI). The GUI may comprise: functionality to visualize and enable manipulation of the at least one 3D model; functionality to enable removal of the visualization of the anatomical structure from the 3D model; functionality to visualize and enable browsing of the medical image stack; and functionality to visualize the position of the medical image that is currently visualized.

Determination and visualization of damage to an anatomical joint

In accordance with one or more embodiments herein, a systemfor customizing an implant is provided. The systemcomprises a processor configured to: i) obtain one or more medical image stacks of a joint; ii) obtain a three-dimensional image representation of the joint based on at least one of said medical image stacks; iii) determine damage to the joint by analyzing said medical image stacks; iv) select an implant template from a predefined set of implant templates having predetermined types and sizes; v) generate a 3D model, in which the marked damage is visualized together with the selected implant template in a proposed position; vi) display the 3D model; vii) receive an approval for said selected implant template in said proposed position; and viii) determine the final shape and dimensions of a customized implant based on said selected implant template and said proposed position.

The present invention relates to a medical implant for cartilage and/or bone repair at an articulating surface of a joint. The implant comprises a contoured implant body and at least one extending post. The implant body has an articulating surface configured to face the articulating part of the joint and a bone contact surface configured to face the bone structure of a joint, where the said articulating and bone contact surfaces face mutually opposite directions and said bone contact surface is provided with the extending post. A cartilage contact surface connects the articulating and the bone contact surfaces and is configured to contact the cartilage surrounding the implant body in a joint. The articulating surface has a layer that consists of titanium nitride (TiN) as the wear-resistant material. The cartilage contact surface has a coating that substantially consists of a material having chondrointegration properties.

In accordance with one or more embodiments herein, a system for creating a decision support material indicating damage to at least a part of an anatomical joint of a patient, wherein the created decision support material comprises one or more damage images, is provided. The system comprises a storage media and at least one processor, wherein the at least one processor is configured to i) receive a series of radiology images of the at least part of the anatomical joint from the storage media; ii) obtain a three-dimensional image representation of the at least part of the anatomical joint which is based on at least a part of said series of radiology images, by generating said three-dimensional image representation in an image segmentation process based on said series of radiology images, or receiving said three-dimensional image representation from a storage media; iii) identify tissue parts of the anatomical joint in at least one of at least a part of said series of radiology images and/or the three-dimensional image representation using image analysis; iv) determine damage to the identified tissue parts in the anatomical joint by analyzing at least one of at least a part of said series of radiology images and/or the three-dimensional image representation of the at least part of the anatomical joint; v) determine suitable sizes and suitable implanting positions for one or more graft plugs based on the determined damage; vi) mark damage to the anatomical joint and suitable sizes and implanting positions for the one or more graft plugs in the obtained three-dimensional image representation of the anatomical joint; and vii) generate a decision support material, where the determined damage to the at least part of the anatomical joint and the suitable sizes and implanting positions for the one or more graft plugs are marked in at least one of the one or more damage images of the decision support material, and at least one of the one or more damage images is generated based on the obtained three-dimensional image representation of the at least part of the anatomical joint.

System and method for creating a decision support material indicating damage to an anatomical joint

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.

Embodiments of the present disclosure relate to design methods for designing a mandrel for hammering, pressing and/or pushing an implant into position in a recess made in a joint and firmly attach the implant to the bone of a patient, the mandrel comprising a contacting surface adapted to be in contact with an articulate surface of the implant to be inserted, the method comprising designing the contacting surface of the mandrel to fit the articulate surface of the implant in that the contacting surface of the mandrel has a cross-sectional profile corresponding to the cross-sectional profile of the implant.
