An interbody implant system for use in the spine includes a base comprising two or more bone contacting surfaces, at least one recess in at least one of the two or more bone contacting surfaces, the recess configured for containing a tooth, a deployable tooth to provide fixation between the base and the anatomy of a subject, a break-away bridge between the tooth and the base for providing a first relative position between the tooth and the base, and a locking mechanism for providing a second relative position between the tooth and the base.

There is provided an osteon template for tissue engineering, including a first plurality of vasculogenic filaments including a first hydrogel and vessel-forming cells, and a second plurality of osteogenic filaments including a second hydrogel and bone-forming cells, wherein the first plurality of vasculogenic filaments is arranged alternately with the second plurality of osteogenic filaments in a concentric arrangement.

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 (“SAI”) trajectory. The implants may be coupled to one or more bone stabilizing constructs, such as rod elements thereof.

A placeholder for vertebrae or vertebral discs includes a tubular body, which along its jacket surface has a plurality of breakthroughs or openings for over-growth with adjacent tissue. The placeholder includes at least a second tubular body provided with a plurality of breakthroughs and openings at least partially inside the first tubular body. The first and second tubular bodies can have different cross-sectional shapes, can be are arranged inside one another by press fit or force fit or can be connected to each other via connecting pins and arranged side by side to one another in the first body.

A medical product, preferably for use in treating, in particular filling and/or closing a bone cavity, wherein the product comprises a plurality of interconnected members, wherein each member has a peripheral boundary and the boundaries of adjacent members engage with one another. And a method for producing a medical product, preferably for use in treating, in particular filling and/or closing a bone cavity, wherein the product comprises a plurality of interconnected members, wherein each member has a peripheral boundary and the boundaries of adjacent members engage with one another.

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 bone implant includes at least one bone-engaging surface designed to mate with an implant-engaging surface of a bone. In the preferred embodiment, the bone-engaging surface of the implant includes a wave pattern comprising at least one peak extending in a proximal direction or at least one valley extending in a distal direction. The implant-engaging surface of the bone also includes a matching wave pattern having at least one peak and valley. Upon mating the engaging surfaces, a bone-implant interface may be created wherein the peaks and valleys of the wave patterns are aligned. As a result, there is good surface contact area at the bone-implant interface which helps prevent loosening or rotating of the implant.

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.

The device for maintaining an intervertebral space is capable of being accommodated inside the disc, in place of the core. Natural anchoring is ensured by promoting the regrowth of fibre around at least part of the device. The possibility of ejection of the residual core is limited in order to avoid a renewed hernia, and mobility of the vertebral column is ensured. To this end, a subject of the invention is a device having at least two non-expansible concentric rings which between them form a free space and which are connected to each other via two junction summits.

Described herein is a bone implant including at least one bone-engaging surface designed to mate with an implant-engaging surface of a bone. In the preferred embodiment, the bone-engaging surface of the implant includes a wave pattern comprising at least one peak extending in a proximal direction or at least one valley extending in a distal direction. The implant-engaging surface of the bone also includes a matching wave pattern having at least one peak and valley. Upon mating the engaging surfaces, a bone-implant interface may be created wherein the peaks and valleys of the wave patterns are aligned. As a result, there is good surface contact area at the bone-implant interface which helps prevent loosening or rotating of the implant.
