On the plus side, the fusion took place where the fifth spinal vertebrae meets the first vertebrae of the sacrum, an area where there is next-to-no rotation. In fact, some people have only four vertebrae and have normal function. Dr. Scott Blumenthal of the clinic said that it’s not unusual for people to have only four spinal vertebrae and have normal function. Moreover, Blumenthal said that athletes from all sports other than power lifting who have the same fusion as Woods are usually able to return to competition after surgery. The estimate for Woods is that he will be fully healed and be able to begin preparing for competition in about six months.
