The present invention provides a method for stabilizing a fractured bone. The method includes positioning an elongate rod in the medullary canal of the fractured bone and forming a passageway through the cortex of the bone. The passageway extends from the exterior surface of the bone to the medullary canal of the bone. The method also includes creating a bonding region on the elongate rod. The bonding region is generally aligned with the passageway of the cortex. Furthermore, the method includes positioning a fastener in the passageway of the cortex and on the bonding region of the elongate rod and thermally bonding the fastener to the bonding region of the elongate rod while the fastener is positioned in the passageway of the cortex.

A spinal implant comprises a first vertebral engaging surface and a second vertebral engaging surface. A wall extends between the surfaces. The wall includes an inner bone growth resistant layer and an outer layer. Systems and methods of use are disclosed.

For the purpose of firmly fusing a low-cost osteosynthetic implant having high osteoconductivity with a bone in a short period of time after implanting without having to perform treatment to restore surface hydrophilicity, a osteosynthetic implant is provided with a substrate that is formed of magnesium or a magnesium alloy and a porous anodic oxide coating that is formed on a surface of the substrate, wherein the anodic oxide coating has an outer surface that, due to the sizes and distribution of pores that are formed when generating the anodic oxide coating by means of anodic oxidation treatment, structurally prevents water from entering the pores while maintaining the hydrophilicity thereof.

A vertebral body spacer of the present invention is used by being inserted between a vertebral body and a vertebral body (intervertebral space). The vertebral body spacer has a block body constituted of titanium or a titanium alloy as a main component thereof, and provided with a pair of contact surfaces to be made contact with the vertebral body and the vertebral body. The block body includes a frame-shaped dense part and a porous part provided inside the dense part, and a porosity of at least a surface of the porous part is larger than a porosity of the dense part. According to the present invention, it is possible to maintain an appropriate size between the vertebral bodies (intervertebral space).

One aspect of the present disclosure relates to a tissue integration device. The tissue integration device can be produced by forming a polymer mixture into a shape. The polymer mixture can include a polymer resin and a growth-promoting medium. Next, at least one polymer forming the polymer resin can be oriented in at least one direction. The shaped polymeric material can then be formed into the tissue integration device.

A reinforced surgical membrane for supporting bone growth by shielding a bone cavity from soft tissue in-growth comprises are a reinforcing layer (2) between a first membrane layer and a second membrane layer (4). The reinforcing layer (2) has defined therein an array of holes (3) which may connect the first and second membrane layers.

An intervertebral prosthesis for insertion by posterior approach, designed to be inserted in pairs between two vertebral bodies, said prosthesis consisting of a prosthesis body extending in a longitudinal direction of intervertebral insertion, including peripheral faces delimiting, on the inside, an inner space for receiving a bone substitute. The prosthesis includes a prosthesis body of which the lower and upper bearing faces have a convex profile having continuously variable convexity in the longitudinal direction. The invention is intended for the treatment of individuals suffering from disc degeneration in the thoracic or lumbar vertebrae.

Biomaterials, implants made therefrom, methods of making the biomaterial and implants, methods of promoting bone or wound healing in a mammal by administering the biomaterial or implant to the mammal, and kits that include such biomaterials, implants, or components thereof. The biomaterials may be designed to exhibit osteogenic, osteoinductive, osteoconductive, and/or osteostimulative properties.

A modular humeral implant for an inverted shoulder prosthesis includes a humeral stem having, on the one hand, a diaphyseal keel of elongate shape, extending along a diaphyseal axis and shaped to be engaged in a medullary cavity of a humerus, and, on the other hand, a metaphyseal portion. A humeral spacer is mounted on the metaphyseal portion of the humeral stem and has a lower face facing the metaphyseal portion, the lower face having a peripheral portion projecting laterally from the metaphyseal portion and covered at least partially with a porous or rough metal surface coating promoting an osseointegration. A humeral insert is fastened on the humeral spacer and has a hemispherical cup shaped to receive a glenosphere of a glenoid implant.

A tool for use with an orthopaedic implant includes: a tubular assembly including a tubular passage having a first end and a second end, the first end including a means for attachment to an implant body; a plug; and a plunger coupled to the plug. The tubular passage is configured to receive, via the second end, a material agent and the plunger coupled to the plug. The plunger is configured to slide through the tubular passage for expelling the material agent from the tubular passage into a load bearing member via the at least one first opening. The plunger is configured to rotate within the tubular passage for coupling the plug with the first opening to seal the first opening against expulsion of the material agent from the load bearing member via the first opening.
