Abstract
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.
