A wooden smartphone case for a portable rectangular electronic device includes a compartment configured to receive and hold the electronic device. The wooden smartphone case includes a main body member, opposite side walls, and a first end wall member and a second end wall member attached to the main body member. Each of the first and second end wall members has a height corresponding to the height of the side walls. At least one of the side walls is structured to apply a force in a perpendicular direction with regard to a longitudinal extension of the at least one side wall, such that an electronic device being arranged in the compartment is held in the compartment, wherein the at least one side wall is structured to apply the force against the electronic device arranged in the compartment along a predetermined length section of the at least one side wall.

Wooden smartphone case for an electronic device

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 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

The present invention relates to a surgical kit, a saw guide and other related tools used in the osteotomy for temporary removal of a piece of a first bone structure to gain temporary access for treatment of defects of a second bone structure, as well as methods for designing and manufacturing said tools.

Tools for assisting in osteotomy procedures, and methods for designing and manufacturing osteotomy tools

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.

Implant for cartilage repair

Osteotomy guide talus

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.

In accordance with one or more embodiments herein, a system for optimizing a position of an implant having an individually customized implant hat and at least one implant protrusion extending from the implant hat in the direction of an implant axis 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; define an implant area that covers at least a major part of the identified damage; position a virtual implant template having an implant hat corresponding to said implant area in the three dimensional virtual model of the joint; and generate a customized top surface of the implant hat to correspond to a simulated healthy cartilage surface. The processor is configured to position the virtual implant template by: placing the virtual implant template so that the cross section area of the implant hat in a direction perpendicular to the implant axis covers at least a major part of the damage; and optimizing the tilt of the implant axis, while maintaining the position of the cross section area of the implant hat in the joint, by minimizing at least one of the maximum penetration depth into the bone along the circumference of the implant hat; the total volume of bone and/or cartilage to be removed for implanting the implant; and/or the surface area of the implant penetration into the bone.
