An implant customization platform may receive image data associated with a bone of a patient. The implant customization platform may convert the image data to a structural representation of the bone. The implant customization platform may identify, based on the structural representation, a placement for an orthopaedic implant relative to the bone. The implant customization platform may determine a performance characteristic for a combination of the bone and the orthopaedic implant. The implant customization platform may determine, using an implant customization model, a data representation of the orthopaedic implant based on the structural representation, the placement, and the performance characteristic. The implant customization platform may perform an action associated with the data representation to permit the orthopaedic implant to be formed.

A method of forming a patient-specific-bone-graft cage based on a patient-specific bone graft cage computer model that is based on a contour of a surface of the bone defining a void, and/or a patient-specific-bone-graft cage that includes a plurality of apertures, that terminate at a location between a front surface and a back surface of the patient-specific-bone-graft cage, for receipt of bone graft material. The patient-specific-bone-graft cage can construct an essential portion (including complex thin anatomical structures) of or substantially the entirety of the mid-face region (e.g., to fill a void in a damaged orbital region), which enables an improved structure reproduction and simplification for the surgeon. For example, the patient-specific-bone-graft cage may be formed based on the contour of the periphery defining the void in the damaged region, and require less modification by a surgeon compared to graft cages formed only by mirroring techniques or normalized models.

An article (e.g., an interbody device) contains a polymer (e.g., polyetheretherketone (PEEK)) and transition metal-doped amorphous magnesium phosphate.

Graft for a bone defect, in particular a tibial head graft for a knee-joint endoprosthesis. It comprises a sleeve-like inner body (2) for implantation at one end of a long bone (99). An outer face of the inner body (2) is designed as a bone contact face (20) for bearing on the surrounding bone margin (97). According to the invention, an outer shell piece (3) is provided which, as a bone replacement piece, is doubled onto the outside of the inner body (2) for filling a defect at the cortical bone margin (97) and is not dimensioned peripherally, such that, in the circumferential direction, it covers only a part of the outer circumference of the inner body (2). The doubled outer shell piece (3) forms a filler piece for a bone defect (bone window 96) at the bone end. Closure of the bone window (96) is achieved, and unwanted contact between the graft and surrounding soft-tissue parts is avoided. Moreover, the graft is thus also supported in the region of the bone window (96). Parts of the bone margin (97) that are still present can thus remain intact, allowing the greatest possible preservation of naturally present bone substance.

A method of joint arthroplasty includes obtaining an image of at least a portion of the tibial plateau. An outer periphery of at least a portion of the tibial plateau is derived based, at least in part, on the image. An implant is provided for the tibial plateau, the implant having a periphery that includes an outer edge that substantially matches the derived outer periphery of the tibial plateau.

Methods and devices are disclosed for the optimization of shoulder arthroplasty component design through the use of computed tomography scan data from arthritic shoulders.

Method for manufacturing a bone pin for connection to a bone, particularly for fixing an implant to a bone, the bone pin having an implant contacting part arranged to contact the implant in connected situation and a bone contacting part arranged to engage the bone in connected situation, wherein the method comprises the steps of:—providing bone information which is indicative for the bone which the bone contacting part is arranged to engage;—providing a bone contacting part which is customized on the basis of the bone information for engaging said bone;—providing an implant contacting part; and—assembling the bone contacting part and the implant contacting part for manufacturing the pin.

Various embodiments of selecting and/or designing one or more aspects of patient-adapted surgical repair systems based, at least in part, on implementation of patient-adapted biomotion simulation models are disclosed herein.

A wrist endoprosthesis (2) for functional replacement of the human wrist, containing a radius component (4) that has a shaft (10) for anchoring in the radius, a head (12), and a first joint surface (16), which is implemented on a distal head face (14), and a carpal component (6) that has a proximal carpal face (22), a distal carpal face (20) and a second joint surface (24) which is formed on the proximal carpal face (22) and interacts with the first joint surface (169) of the radius component (4), characterized in that the carpal component (6) is substantially trough-shaped, in order to at least partially surround the carpal bones. Also, a wrist endoprosthesis (2) that has anti-luxation protection (8), a method for producing wrist endoprostheses (2) and a computer program product.

A femoral orthopaedic prosthesis includes a metallic core extending from a proximal end to a distal tip. The metallic core includes a neck that is positioned at the proximal end and is configured to receive a prosthetic femoral ball. An elongated stem extends distally from the neck to the distal tip. The stem includes a proximal section extending distally from the neck, and a distal section that extends proximally from the distal tip. The elongated stem also includes a pair of spaced-apart beams that connect the proximal section to the distal section. An aperture is defined in the stem between the pair of spaced apart beams.
