An implant for therapeutically separating bones of a joint has two endplates each having an opening through the endplate, and at least one ramped surface on a side opposite a bone engaging side. A frame is slideably connected to the endplates to enable the endplates to move relative to each other at an angle with respect to the longitudinal axis of the implant, in sliding connection with the frame. An actuator screw is rotatably connected to the frame. A carriage forms an open area aligned with the openings in the endplates. The openings in the endplates pass through the carriage to form an unimpeded passage from bone to bone of the joint. The carriage has ramps which mate with the ramped surfaces of the endplates, wherein when the carriage is moved by rotation of the actuator screw, the endplates move closer or farther apart.

A spinal prosthesis is provided, more particularly a spinal prosthesis having component parts capable of assembly during surgery in a spinal environment for providing stability and flexibility to the spine. The component parts include a ball-and-socket combination, a compressible pad, and anchors at each end of the prosthesis to secure the prosthesis in the spine.

A soft tissue repair system is provided for covering or filling openings in the annulus of an intervertebral disc. The soft tissue repair system uses a single plug or a combination of a first plug and a second plug. The second plug is a flowable plug such as an adhesive material or a material that hardens to a flexible plug material. Each plug is configured to close the opening in the annulus and can be positioned within the opening, over the opening at the exterior surface or over the opening at the interior surface. The plug can also be combined with a clamping mechanism that engages the annulus to secure the plug in the opening.

The present disclosure relates to a knee joint augment having an anatomical shape. More specifically, the present disclosure relates to a knee joint augment that is used for artificial joint replacement to replace lost bone, wherein the augment is used in artificial knee replacement surgery to be coupled to a knee implant. The augment includes a top surface configured to be brought into contact with a distal surface of a base plate that forms the body of a tibia element and a bottom surface configured to be brought into contact with a cut surface of a tibia. The bottom surface has an area smaller than that of the top surface, and has a tapered shape that narrows from the top to the bottom. An intermediate line at which one end surface cut to be perpendicular to the top surface and an outer surface meet each other has a shape that is outwardly convex to the outside of the augment with respect to a straight line connecting a top point where the intermediate line and the top surface meet and a bottom point where the intermediate line meets the bottom surface, whereby the intermediate line has a shape corresponding to the anatomical shape of a cut bone.

A bone implant for enclosing bone material is provided. The bone implant comprises a covering, which can be a biodegradable mesh. The covering is configured to be rolled into a diameter to at least partially enclose the bone material within the covering. In some embodiments, the covering includes a body portion and a closure portion adjacent to the body portion. The closure portion is configured to hold the covering in a rolled configuration to a predetermined diameter to at least partially enclose the bone material. A kit and a method of using the bone implant are also provided.

Implant assemblies, systems, and methods for stabilizing a joint between a superior vertebra and an inferior vertebra may include a plate member coupled to an interbody spacer with at least one fastener that extends superiorly or inferiorly from the implant assembly to anchor within a vertebral body and stabilize the joint. Inserters and methods of insertion may also be included to facilitate fixation of various implant assemblies within the intervertebral space of the joint between the superior vertebra and the inferior vertebra.

An implant to fill a hole in tissue, such as bone tissue, comprising a first portion that is insertable through the hole when in a first compressed position, wherein the first portion cannot pass through the hole when in a first deployed position; and a second portion that cannot pass through the hole when in the second deployed position. The first and second portions of the implant can be deployed independently. Therefore, in operation, it is possible to insert the first portion of the implant through the hole when in the first compressed position, deploying the first portion to transition it to the first deployed position while the second portion remains in the second compressed position, and then deploying the second portion to transition it to the second deployed position. The devices and methods may be used, for example, in transsphenoidal or other orthopedic surgeries involving bone tissue.

The present disclosure relates to a spinal fusion impactor tool that includes an attachment means for securing an implant device to the distal end of the tool, a means for adjusting the angle of the distal head relative to the handle to better position the implant for introduction into the implant site, means for remotely releasing the implant device at the distal end and a clamp device on the shaft of the tool to secure tabs, attachments and other devices. The impactor tool is preferably used in conjunction with implantation of an intervertebral fusion cage that is equipped with shims having tabs or other removing means, but may also be used to introduce, for example, an implant, graft, fusion device, wedge or distractor device into any joint space or bony region in preparation for implantation.

A spinal implant system includes at least one interbody implant having a first member including a tissue engaging surface and at least one mating element. A second member includes a tissue engaging surface and at least one mating element. An intermediate member includes at least one mating element. An intra-operative surgical tool is connectable with at least one of the members to engage adjacent mating elements and fix the intermediate member with at least one of the first member and the second member. Implants, surgical instruments and methods are disclosed.

An interbody system for implanting between vertebrae, the interbody system comprises a cage having a cage body that includes a graft chamber having a volume that receives graft material, a sagittal wall that forms a portion of the graft chamber, and a wall membrane that forms another portion of the graft chamber. The interbody system may comprise an interbody device that includes an aperture that receives a bone fastener, wherein the wall membrane interacts with the bone fastener. The wall membrane may bend as result of a force applied by the bone fastener to a portion of the wall membrane, thereby providing directional support to the bone fastener and/or forcing graft material from the graft chamber.
