摘要：
A spinal implant for stabilizing two adjacent vertebrae having a damaged disc therebetween is assembled in situ. An elongated tool is used to insert a flat U-shaped distractor in the disc space through a low profile incision with both legs of the U-shaped distractor contacting both end plates of the adjacent vertebrae. The tool is rotated 90 degrees rotating the distractor 90 degrees so that each leg of the distractor contacts one end plate of the adjacent vertebrae, respectively, to restore intervertebral space. An elliptical bone tray is slid along the tool to seat within the U-shaped distractor. The tool is removed and a retainer replaces it to lock the bone tray and the distractor together. A screw is used to lock the bone tray to the distraction device, the screw slides down the cannula which is the tool inserted over the rod that the distraction implant is attached to.
