A humeral implant component connectable to another humeral implant component, the humeral implant component comprising: a longitudinal axis, a first end and a second end, the first end and the second end opposing each other along the longitudinal axis of the humeral implant component, and an interface part for connecting the humeral implant component to the other humeral implant component, wherein the interface part is tapered along the longitudinal axis in a direction from the second end to the first end, the interface part being engageable with a tapered interface part of the other humeral implant component to form a tapered connection between the humeral implant component and the other humeral implant component, wherein the humeral implant component further comprises a through hole extending along the longitudinal axis for locking the tapered connection by a longitudinal fastener.

Shoulder arthroplasty systems and configurations for components thereof are described. For example, implant systems for a total should arthroplasty (TSA), hemi shoulder arthroplasty, and reverse should arthroplasty (RSA) are described. In addition, exemplary configurations for baseplates, glenoid components, glenosphere components, humeral components, humeral head components, humerosocket components, connectors, and adaptors, are described.

A method for producing bone grafts using 3-D printing is employed using a 3-D image of a graft location to produce a 3-D model of the graft. This is printed using a 3-D printer and a printing medium that produces a porous, biocompatible, biodegradable material that is conducive to osteoinduction. For example, the printing medium may be PCL, PLLA, PGLA, or another approved biocompatible polymer. In addition such a method may be useful for cosmetic surgeries, reconstructive surgeries, and various techniques required by such procedures. Once the graft is placed, natural bone gradually replaces the graft.

Provided herein are biomimetic osteochondral implants that are generally useful for the at least partial resurfacing of damaged cartilage within a joint. The implants are constructed to have a modular, layered structure in which the physical properties (e.g., stiffness and lubricity) or dimensions of each layer can be adjusted (e.g., by using the appropriate material and controlling the thickness thereof) based on the anatomy to be replaced. For example, the material and or thicknesses of the layers can be selected to approximate the physical properties and/or dimensions of cartilage (and, optionally, chondral and subchondral bone). Also provided herein are methods of treatment involving the use of said biomimetic osteochondral implants to repair an osteochondral defect in a joint.

The present invention relates to a stem for or of an implant having a longitudinal axis and at least one recess adapted for cemented implantation into the medullary cavity and/or a cavity created by surgery of a long bone, characterized in that the recess is interrupted by a barrier. Further the present invention relates to a method for preparing a stem of an implant according to any one of the preceding claims for implantation, comprising the step of placing cement into the recess (12) on both sides of the barrier.

The present disclosure provides an implant component assembly for a joint replacement. The assembly comprises an implant component, the implant component including an interface part for attaching another implant component and an assembly channel. The assembly further comprises an assembly screw for securing the other implant component to the implant component, the assembly screw having a longitudinal axis, a screw head, and a screw shank and being insertable into the assembly channel. A screw retention unit of the assembly is configured for keeping the assembly screw within the assembly channel and allowing rotation of the assembly screw about the longitudinal axis.

A medical honeycomb structure lacking at least a portion of an outer peripheral side wall of a honeycomb structure that includes a plurality of through-holes extending in one direction, wherein sites lacking the outer peripheral side wall have a plurality of grooves, and have a plurality of planes including distant surfaces of groove side walls flanked by the grooves.

The present invention relates to bone-implants for treating a lesion on a bone, comprising: a bone anchor, a container in communication with the bone anchor and an osteoconductive bone-filler material inside the container, and methods thereof.

Shoulder arthroplasty systems and configurations for components thereof are described. For example, implant systems for a total should arthroplasty (TSA), hemi shoulder arthroplasty, and reverse should arthroplasty (RSA) are described. In addition, exemplary configurations for baseplates, glenoid components, glenosphere components, humeral components, humeral head components, humerosocket components, connectors, and adaptors, are described.

Systems and methods are provided for implant design and manufacturing to optimize the bone-implant interface. The implant design and methodology may include accounting for the anatomy of a bone of a subject to address optimize the bone-implant interface considerations for the subject. Implants or components may be asymmetrically designed to better match the associated anatomy as well as optimize the bone-implant interface, such as by quantifying bone density and matching material properties of the implant or coatings of the implant. Information derived from the methodology can be used to guide the design of the implant resulting in an asymmetric design that optimizes the bone-implant interface.
