A bone graft delivery system and method for using same to deliver graft material into a surgical site. The system includes an interbody implant having a securing site disposed on a surface of the implant and a holder having an elongated, hollow handle including a distal end. The distal end of the holder is configured to removably engage the securing site of the interbody implant to secure the interbody implant to the distal end of the holder until such time as a user desires to disengage the holder from the interbody implant. The interbody implant may be a cage implant having opposing anterior and posterior surfaces, opposing first and second lateral surfaces, and opposing top and bottom surfaces, wherein the top surface comprises a first aperture and the bottom surface comprises a second aperture, the posterior surface comprising a third aperture, the first, second, and third apertures all linking to a main cavity, the main cavity generally extending between the top surface and the bottom surface.

A proposed treatment of arthrosis/osteoarthritis in a joint of a mammal or human patient involves deposing a liquid material on at least one damaged surface of the joint. To accomplish this, a reservoir (110) is provided, which holds a volume of a biocompatible material in liquid form outside of a body containing the joint (J) to be treated. A proximal end (P) of a tube-shaped instrument (120) is connected to the reservoir (110), and a distal end (D) of the instrument (120) is inserted into the joint (J). The liquid material is fed through the instrument (120) to the distal end (D) for deposition on the at least one damaged joint surface.

The material is configured to assume a solid form under predefined conditions (e.g. when cooling off, or being exposed to a specific type of radiation). When the material has the solid form, it has a resistance to wear adapted to replace a worn out joint surface.

A novel and improved elbow prosthesis and method of implanting same including a prosthesis system that has a retaining system. The joint prosthesis system can include an implant, and an alignment guide. The alignment guide can include a post member extending through a central axis of rotation in a prosthesis and a drill guide member having a first limiting member for limiting articular surface removal from a joint. The first limiting member can include a recessed guide for positioning the implant.

A bone joint spacer has two endplates which have a bone engaging surface on one side, and ramps extending from an opposite side. A shaft has a threaded end, and another end which has ramp followers which mate with the endplate ramps of both endplates. A collar slides over the threaded end of the shaft, and also has ramp followers which mate with the endplate ramps of both endplates. A nut threads onto the end of the shaft and pushes the collar towards the ramp followers of the shaft. This movement causes the ramp followers to slide the ramp followers of the collar and the shaft against the endplate ramps, pushing the endplates apart. Two of these spacers can be combined by a link plate so that the spacers can be aligned or curved into a U-shape to be inserted into the body and positioned between bony surfaces, respectively.

A device for mechanical securement to hard tissue of a subject, the hard tissue having an end surface defining a direction of curvature such that over at least a portion of the surface, a total curvature of at least 180 degrees is defined, the device comprising a body portion comprising at least four contact points, three contact points of the four contact point span over 180 degrees of total curvature of the end surface in a plane defined by the three contact points, and a fourth contact point outside the plane, the four contact points providing mechanical securement of the body portion to the hard tissue.

A method is provided for performing a quadruped unicompartmental stifle arthroplasty. The method includes cutting a plateau of a tibia to form first cut surfaces. The method also includes cutting a medial condyle of a femur to form second cut surfaces. The method also includes aligning openings in a first trial device with the first cut surfaces and forming first holes in the first cut surfaces by passing a drill through the openings in the first trial device. The method also includes aligning openings in a second trial device with the second cut surfaces and forming second holes in the second cut surfaces by passing a drill through the openings in the second trial device. The method also includes mounting a first implant device to the first cut surfaces and mounting a second implant device to the second cut surfaces. A system is also provided for performing the method.
