Implants for the fusion or fixation of two bone segments are described. For example, the implants can be used for the fusion or fixation of the sacroiliac joint. The implants can include fenestrations, have a rectilinear overall cross-sectional area, and have a curvature. Some implants can also be used to rescue failed implants.

A medical product (100), preferably for use in treating, in particular filling and/or closing a bone cavity, wherein the product (100) comprises a plurality of interconnected members (110), wherein each member (110) has a peripheral boundary (120) and the boundaries (120) of adjacent members (110) engage with one another. Also, a method for producing the medical product (100) and a medical kit that comprises the medical product (100) and a securing element for securing the product (100) in a bone cavity and to a method for filling a bone cavity.

An optical tracker and a surgical device. The surgical device includes a shaft defining a longitudinal axis. The shaft has a first shaft portion configured to be inserted into a patient, and a second shaft portion configured to be located outside the patient when the first shaft portion is inserted in the patient. The surgical device further includes an actuation member actuatable relative to the first shaft portion, and an operation member operable relative to the second shaft portion. The operation member is configured to actuate the actuation member when being operated. Further, the surgical device includes a tracker coupled with the operation member so that operation of the operation member causes the tracker to move relative to the shaft, such as to rotate around the longitudinal axis.

The present invention includes markers for use in implants that have a variable lucency or radiolucency. The use of a variably lucent marker can provide a surgeon a quick indication of the implant's alignment during implantation. A variably lucent marker can also provide a doctor or technician a quick indicator of an implant's position during post-operation imaging.

The variably lucent markers can be used in any implant that has some level of lucency when viewed through an imaging device. The variably lucent markers can be used in the lattice with increased or optimized lucency disclosed herein or in other structure known in the art.

The biocompatible lattice structures disclosed herein have an increased or optimized lucency, even when constructed from a metallic material. The lattice structures can also provide an increased or optimized lucency in a material that is not generally considered to be radiolucent.

The biocompatible lattice structures disclosed herein with an increased or optimized lucency are prepared according to multiple methods of design disclosed herein. The methods allow for the design of a metallic material with sufficient strength for use in an implant and that remains radiolucent for x-ray imaging.

A shoulder implant system includes a humeral stem implant, a humeral neck implant component, a humeral head implant component, and a glenoid implant. The humeral stem implant has a fin coupled to an exterior surface thereof that is inwardly tapered at an angle relative to vertical. At least a portion of the fin forms a wedge that directly engages and compacts cancellous bone during installation of the humeral stem implant. The humeral neck implant component is configured to be coupled with the humeral stem implant. The humeral head implant component is configured to be coupled to the humeral stem implant via the humeral neck implant component. The glenoid implant has a plurality of peripheral pegs. Each of the peripheral pegs has a plurality of sets of resilient lobes.

The biocompatible lattice structures and implants disclosed herein have an increased or optimized lucency, even when constructed from a metallic material. The lattice structures can also provide an increased or optimized lucency in a material that is not generally considered to be radiolucent. Lucency can include disparity, maximum variation in lucency properties across a structure, or dispersion, minimum variation in lucency properties across a structure. The implants and lattice structures disclosed herein may be optimized for disparity or dispersion in any desired direction. A desired direction with respect to lucency can include the anticipated x-ray viewing direction of an implant in the expected implantation orientation.
