A revision-implant receiver (18) is provided for supporting an implant (20) of a revision joint replacement (10). The revision-implant receiver (18) comprises a first receiver element (22) and a second receiver element (24). The first receiver element (22) and the second receiver element (24) are engaged with each other via a hinge element (26).

Systems and methods here include a meniscal allograft with a bone block and a technique for making a desired shape in the bone block to be used to implant in a patient. A clamp and/or jig arrangement are disclosed that are able to secure the tissue and allow three corresponding cuts to the tissue using the clamp as a guide to a saw to obtain the desired shape.

An expandable spinal fusion implant including a housing, upper and lower endplates, a wedge positioned within the housing and between the upper and lower endplates and a drive mechanism to urge the wedge distally between the upper and lower endplates to increase the separation between the endplates and expand the overall height of the distal end of the implant.

A surgical component, a kit including the surgical component, and a surgical method. The surgical component includes a body portion. The surgical component also includes an elongate stem for inserting into an intramedullary canal of a patient. The elongate stem extends distally from the body portion. The elongate stem has a longitudinal axis; a proximal end; a distal end; and a plurality of splines located on an outer surface of the stem. The splines are circumferentially arranged around the stem. At least some of the splines are tapered such that each tapered spline is narrower at a distal part of that spline than at a part of that spline that is proximal with respect to the distal part. The surgical component further includes an elongate neck portion extending from the body portion at a non-zero angle with respect to the longitudinal axis of the stem.

A pedicle insulator implant is designed to protect the nerves and surrounding tissue from injury by pedicle screws or other surgical devices and instruments. The implant is configured to shield a fixture, reduce nerve root irritation, and diminish loosening of the fixture, when the fixture is implanted into the void of a target site. The implant includes features for stabilizing and securing the implant within the void at the target site. For example, in one embodiment, the implant includes one or more ridges and one or more teeth sections that stabilize the implant against rotational and extractive forces that could disturb the implant.

An orthopaedic prosthetic component is provided. The orthopaedic prosthetic component comprises a porous three-dimensional structure shaped to be implanted in a patient's body. The porous three-dimensional structure comprises a plurality of unit cells. At least one unit cell comprises a first geometric structure having a first geometry and comprising a plurality of first struts, and a second geometric structure having a second geometry and comprising a plurality of second struts connected to a number of the plurality of first struts to form the second geometric structure.

The present invention relates generally to medical devices, systems, and methods for use in surgery. In particular, the disclosed system and methods relate to an intervertebral spinal implant sized and dimensioned for the lumbar spine implantable via a posterior approach. The system includes an implant, instruments for delivering the implant.

A bone implant holding and shaping tray is provided. The tray includes a first segment having a distal end and a first surface sized to hold and shape at least a portion of the bone implant with bone material. The tray includes a second segment having a second surface sized to hold and shape at least a portion of the bone implant with bone material, the second segment having a proximal end configured to be coupled to the distal end of the first segment so as to extend the first surface to hold and shape the bone implant. Methods of making and using the bone implant holding and shaping tray are also provided.

A spinal implant configured for positioning within a space between adjacent vertebral bodies includes an upper end plate including an outer surface extending between first and second end surfaces and opposed side surfaces. The outer surface includes a first convex profile extending between the first and second end surfaces and a second convex profile extending between the opposed side surfaces. The first convex profile and the second convex profile have different curvatures. The spinal implant further includes a lower end plate and a core disposed between the upper and lower end plates and coupled thereto. A method of assembling a spinal implant and a method of performing spinal surgery are also disclosed.
