There is provided a tibial component (100) comprising a tibial tray (102) having a superior side and an inferior side, and a support member (104) connected to the inferior side of the tibial tray, the support member having a stem portion (120), the stem portion including one or more fins (130) and a first arm (134) angled relative to a second arm (136). In one form, the fins have a curvature that extends away from the stem portion. In another form, the first arm defines an opening sized to receive an anchor wherein the anchor is configured to penetrate a portion of bone and the opening in the first arm. Optionally, the stem portion includes a first portion (1022) having a first cross sectional area and a second portion (1024) having a second cross sectional area wherein the first cross sectional area is larger than the second cross sectional area. The fins and arms can include rail protrusions (1186).

Provided is a composition for a scaffold having a mineral coating similar to bone. Also provided is a method for mineral coating a scaffold so as to promote mineral coating of the scaffold with a plate-like nanostructure and a carbonate-substituted, calcium-deficient hydroxyapatite phase.

An intervertebral implant component of an intervertebral implant includes an outer surface for engaging an adjacent vertebra and an inner surface. A keel extends from the outer surface and is designed to be disposed in a slot provided in the adjacent vertebra. This keel extends in a plane which is non-perpendicular to the outer surface; and preferably there are two of the keels extending from the outer surface which are preferably offset laterally from one another. In another embodiment, an anterior shelf is provided at an anterior end of the outer surface, and this anterior shelf extends vertically away from the inner surface in order to help prevent bone growth from the adjacent vertebra towards the inner surface. Further in accordance with disclosed embodiments, various materials, shapes and forms of construction of the component and/or keel provide various benefits.

In various embodiments, an implant for interfacing with a bone structure includes a web structure including a space truss. The space truss includes two or more planar truss units having a plurality of struts joined at nodes and the web structure is configured to interface with human bone tissue. In some embodiments, a method is provided that includes accessing an intersomatic space and inserting an implant into the intersomatic space. The implant includes a web structure including a space truss. The space truss includes two or more planar truss units having a plurality of struts joined at nodes and the web structure is configured to interface with human bone tissue.

A prosthesis system comprises plates that can be positioned against vertebrae and a selected resilient core that can be positioned between the plates to allow the plates to articulate. The selected resilient core can be chosen from a plurality of cores in response to patient characteristics, such as age and/or intervertebral mobility, such that the prosthesis implanted in the patient is tailored to the needs of the patient. The plurality of cores may comprise cores with different resiliencies, and one of the cores can be selected such that the upper and lower plates articulate with the desired shock absorbing resiliency and/or maximum angle of inclination when the one selected core is positioned between the plates.

Systems, kits and methods for long bone arthroplasty that include arrays of humeral head prosthesis components, each having on a first side a bone articulation surface that has an overall generally hemi elliptical convex shape defined by a major axis and a minor axis, the bone articulation surface having an apex and a base that each has an non-circular elliptical cross sectional shape, the prosthesis components having on an opposite side, adjacent the base, a bone contact surface. The humeral head prosthesis components in the arrays vary from having a base with a more circular cross sectional shape to a more elongated elliptical cross sectional shape with increasing size.

A device for a metatarsophalangeal (MTP) joint includes a body with a stem and a head. The stem may be hollow and include a plurality of perforations about its length to improve osseointegration. The head may include one or more perforations and/or one or more islands. The one or more perforations and one or more islands are configured to promote bonding the body and liquid-crystalline elastomer (LCE) that is applied to the head. The device may be inserted into bone to form an MTP joint replacement.
