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.

Bone implants, including methods of use and assembly. The bone implants, which are optionally composite implants, generally include a distal anchoring region and a growth region that is proximal to the distal anchoring region. The distal anchoring region can have one or more distal surface features that adapt the distal anchoring region for anchoring into iliac bone. The growth region can have one or more growth features that adapt the growth region to facilitate at least one of bony on-growth, in-growth, or through-growth. The implants may be positioned along a posterior sacral alar-iliac (“SAT”) trajectory. The implants may be coupled to one or more bone stabilizing constructs, such as rod elements thereof.

The intervertebral fusion device (200) comprises a superior component (220), an inferior component (240) and a core component (260). The superior and inferior components (220, 240) are received in an intervertebral space between first and second vertebrae whereby the superior component top side abuts against the first vertebra, the inferior component bottom side abuts against the second vertebra, and the superior component bottom side and the inferior component top side oppose each other. A height of the intervertebral fusion device is determined upon insertion of the core component (260) between the superior and inferior components (220, 240). Each of the superior component top side and the inferior component bottom side is one of: oblong having a major axis; and square, being bounded by four edges. During insertion of the core component (260) a first core profile of the core component cooperates with a superior component profile at the superior component bottom side and a second core profile of the core component cooperates with an inferior component profile at the inferior component top side whereby the core component moves in a direction oblique to the major axis where the superior component top side or the inferior component bottom side is oblong or to an edge of the superior component top side or the inferior component bottom side where the superior component top side or the inferior component bottom side is square.

A joint replacement system for repairing an articular surface of a first bone of a joint includes an anchor portion and an implant portion. The anchor portion includes an anchor to be secured to the bone, and an anchor fixation head including a bone-facing surface (BFS) extending radially outward from the anchor and an implant facing surface (IFS) extending from a periphery of the BFS. The implant portion is formed from a material (e.g., CoCr) more dense than the material of the anchor portion (e.g., Ti) and includes a fixation cavity to receive at least a portion of the anchor fixation head (AFH), the fixation cavity includes an anchor facing surface (AFS) configured to form a frictional connection with the IFS, and a load bearing surface having a contour for articulating against a cooperating articulating surface of a second bone of the joint.

A flexible bone implant includes a proximal stem having a proximal end, a distal end, and a proximal conduit extending from the proximal end to the distal end of the proximal stem, whereby the proximal conduit is open at both the proximal and distal ends of the proximal stem. The implant includes a distal stem having a proximal end, a distal end, and a distal conduit extending from the proximal end to the distal end of the distal stem, whereby the distal conduit is open at both the proximal and distal ends of the distal stem. The implant includes a flexible hinge interconnecting the distal end of the proximal stem with the proximal end of the distal stem for allowing the proximal and distal stems to flex relative to one another. A proximal stem protective tube is disposed within the proximal conduit of the proximal stem and has a length that matches the length of the proximal conduit, and a distal stem protective tube is disposed within the distal conduit of the distal stem and has a length that matches the length of the distal conduit. The proximal stem, the distal stem and the flexible hinge comprise a unitary structure made of a polymer material.

A method of treating a hip joint of a human patient using a pelvic drill comprising a driving member, a bone contacting and an operating device for operating said driving member. The method comprise the steps of creating a hole passing through the pelvic bone and into the hip joint of the human patient, and providing at least one hip joint surface to the hip joint, through said hole in the pelvic bone of the human patient. In one embodiment the method includes inserting a needle or tube like instrument into the patient's body for filling a part of the patient's body with gas and thereby expanding a cavity within the body.

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 have a matrix structure, have a rectilinear cross-sectional area, and have a curvature.

A kit includes a distractor, a plurality of trial elements, and at least one sensor. The distractor is configured to separate a first bone from a second bone by adjusting the distance between a first member and a second member, and is configured to receive at least one sensor in the first portion. Each of the trial elements corresponds to one of a plurality of surgical implants, is configured to be temporarily coupled to the second bone so as to evaluate suitability of the corresponding one of the plurality of surgical implants for implantation, and is configured to receive at least one sensor. The at least one sensor is configured to be received in the distractor or one of the trial elements, and is configured to record a magnitude of a force, a direction of application of a force, a pressure mapping, or a location of application of a force.

An artificial knee joint comprises a femoral condyle prosthesis and a tibial plateau prosthesis; wherein the tibial plateau prosthesis includes a medial tibial plateau prosthesis and a lateral tibial plateau prosthesis disposed at both sides of the tibial plateau intercondylar eminence, respectively. The artificial knee joint further comprises a locating pin for fixing the tibial plateau prosthesis. The bottom surface of the tibial plateau prosthesis is provided with a prosthetic notch, and the tibia below the tibial plateau prosthesis is provided with a tibial notch. The prosthetic notch corresponds to the tibial notch, together forming a limiting hole for accommodating the locating pin. The cooperation between the locating pin and the limiting hole can ensure relative position stability and balance between the medial tibial plateau prosthesis and the lateral tibial plateau prosthesis.

Compositions comprising a cartilage sheet comprising a plurality of interconnected cartilage tiles and a biocompatible carrier are provided. Methods of manufacturing cartilage compositions comprising a cartilage sheet comprising a plurality of interconnected cartilage tiles are also provided.
