摘要： Methods and instrumentation for spinal interbody fusion are disclosed. The instruments and methods are particularly adapted for interbody fusion in an unreamed disc space. One instrument is a distractor assembly including a first distractor and a second distractor configured to be inserted in side-by-side relation in the disc space. Fusion cages adapted for insertion into an unreamed disc space are provided to enhance load distribution between adjacent vertebral bodies and lateral stability of the spinal column. The fusion cages may be inserted after distracting the disc space with the distractor assembly. Instruments for preparing the disc space through the inserted fusion cages or for use with the distractor assembly are also provided.

摘要： An instrument for bone distraction and compression is provided which has been fitted with ratcheting tips that are rotatably mounted at the working end of a bone distractor. The ratcheting tips are mounted such that they are adjustable to customize the instrument for a particular surgical procedure. The tips may be used to push implants along the rod. The tips can include U-shaped ends that slide around the rod hooks or other components to urge the two to desired positions. It is preferred that the members of the handle are coupled such that when opened, the working ends of the instrument remain parallel to one another.
