ABSTRACT:
An improved four-legged distractor with multiplanar adjustability facilitates intervertebral bone grafting. The legs are slidably fixed to a rectangular frame so that the space between opposing legs and the space between adjacent legs may be varied. The bottom portion of each leg is offset so that a large space is created between the top portion of the legs to permit easy access to the operating space.
