A system includes a first implant component and a second implant component. The first implant component is configured to be secured to a bone and includes a plate and a coupler extending upward from the plate and defining a coupler axis. The second implant component is configured to be coupled to the first implant component. The second implant component includes an articulation surface and defines a cavity configured to receive the coupler of the first implant component. The second implant component is couplable to the first implant component at a plurality of rotational orientations about the coupler axis.

A device and methods for intervertebral spinal fusion of adjacent intervertebral bodies. An intervertebral spacer is positioned within a narrow disc space between adjacent intervertebral bodies of a patient. The spacer is arranged with upper and lower guides. The guides are adapted to simultaneously guide the deployment of upper and lower anchors of an anchoring device into their respective intervertebral bodies. The spacer is also adapted to lock the upper and lower anchors to the spacer in the deployed position.

This invention corresponds to a prosthesis for total or hip resurfacing replacement, which comprises a prosthetic femoral head made of highly cross-linked polyethylene, with a diameter ranging from 38 mm to 64 mm, to articulate with a cup or acetabular component made of metal. When the invention applies to total hip replacement, the polyethylene head includes a metal core, which contains inside the female counterpart (14) to mate with the male counterpart (13) of a Morse taper, located at the upper end of the femoral component. The use of this type of head for total hip replacement, articulated with an ultra-polished acetabular cup, reduces the risk of dislocation, transmits less angular and torque forces to the Morse taper than large metal heads, and avoids the problems related to the metal-metal bearing or with the use of large metal heads with thin polyethylene. When the invention relates to hip resurfacing replacement, the highly cross-linked polyethylene femoral head has a lower polyethylene extension or stem with or without internal metal reinforcement (151) or a metal stem integrated into a metal-back (152). Using these types of heads for hip resurfacing replacement heads eliminates the problems associated with metal-on-metal resurfacing replacements.

A two part annulus repair rivet for repairing a defect in the annulus of an intervertebral disc includes a first part delivered through a port and adapted to be positioned at an internal surface of an annulus adjacent a defect and a second part adapted to be positioned on an external surface of the annulus adjacent the defect. The first and second parts are secured together, repairing the defect.
