A device for containing bone graft material comprises a body including an inner sleeve extending longitudinally from a proximal end to a distal end and an outer sleeve surrounding the inner sleeve and extending longitudinally from a proximal end to a distal end such that a bone graft collecting space is formed therebetween.

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 medical implant porous scaffold structure having low modulus, wherein said structure is formed by multiple basic units superposed sequentially along the three-dimensional directions in three-dimensional space, each of the basic units is composed of a quadrangular prism or hexagonal prism having central interconnected pores encircled by four or six side walls, each of the side walls is composed by a “X-type” frame structure formed by two crossed ribs, and the central interconnected pores of the adjacent basic units arranged along the axis direction of the quadrangular prism or the hexagonal prism are interconnected to each other. The structure could not only reduce the modulus of the implant, make the modulus of the implant and strength achieve an ideal match, improve the configuration of traditional metal implants to optimize the distribution of mechanical and weaken the stress shielding effect; but also has a regular interconnected pores structure which is conducive to bone tissue in-growth, and can increase mutual locking of bone tissue and implant and shorten the recovery time of patients.

An article (e.g., an interbody device) contains a polymer (e.g., polyetheretherketone (PEEK)) and transition metal-doped amorphous magnesium phosphate.

An intervertebral implant for insertion into an intervertebral disc space between adjacent vertebral bodies or between two bone portions. The implant includes a spacer portion, a plate portion operatively coupled to the spacer portion and one or more blades for securing the implant to the adjacent vertebral bodies. The blades preferably include superior and inferior cylindrical pins for engaging the adjacent vertebral bodies. The implant may be configured to be inserted via a direct lateral trans-psoas approach. Alternatively, the implant may be configured for insertion via an anterior approach.

An orthopedic prosthesis includes a head which internally accommodates the major motion of a patient, e.g., during walking, thereby reducing wear against a cup or liner. A neck may be utilized which rotates within the distal member about an axis aligned with the major motion of the patient. The orthopedic prosthesis may also include a sacrificial anode, a seal made of natural fibers, and utilize lubricant made of honey.

Disclosed is an expandable interbody fusion implant that is configured to have an initial configuration having a first footprint width suitable for being inserted into an intervertebral space and an expanded configuration having a second footprint width that is greater than the first footprint width. The implant may include a first body member and a second body member that is pivotally coupled to the first body member. The implant may be expanded using an inflatable balloon. The implant may be expanded bilaterally such that both body members rotate relative to the other or the implant may be expanded unilaterally such that one of the body members rotates relative to the other.

An implant having a unitary body includes an intramedullary portion and an extramedullary portion. The intramedullary portion is sized and structured to be received within an intramedullary canal of a first bone and defines a longitudinal axis. The extramedullary portion includes a surface defining an axis that is disposed at an angle with respect to the longitudinal axis. An aperture defined along the extramedullary portion is sized and configured to receive a fastener therein for coupling the extramedullary portion of the implant to a second bone.
