    摘要: An intervertebral prosthetic implant having a first endplate having a first surface configured to substantially engage with a first vertebral body and a second surface having an extension with a concave contact surface, the concave contact surface being spaced apart from the second surface. A second endplate is provided with a first surface configured to substantially engage with a second vertebral body and a second surface comprising a convex contact surface, and the second endplate having a securing element positioned along and above the second surface defining a first and second window on opposing sides of the second surface. The securing element extends along the width and length of the lower endplate and configured with an access hole. An extension portion extends from the first surface of the first endplate through the access hole of the securing element and contacts the second surface of the second endplate.

    摘要: The present invention generally is directed toward a spinal fixation system whereby a coupling element allows the physician to selectively lock or unlock either the connection between the coupling element and a fastener, such as to allow for repositioning of the coupling element, or the connection between the coupling element and an elongate rod. The locking or unlocking of these connections may be made independently and as desired by the physician.

    摘要: A prosthetic device can be used as a prosthesis following a discectomy or a corpectomy. The prosthetic device includes two endplates with staggered motion limiting members. The device can be configured to allow six degrees of motion when comparing one endplate relative to the other. The endplates can be configured to fix the joint by changing the body held within the device and by adding a locking plate and fasteners. A method teaches how to insert a device to an intervertebral space via an anterior incision.
