Definition: An osteotomy is a surgical procedure to realign or remove a segment of bone. Most often, an osteotmy is performed to realign a deformed bone. The bone is cut with surgical instruments, realigned, and allowed to heal in its new position.
In many surgical procedures, the osteotomy is just a part of the surgery. Often, the bone that has been cut is then held in its new position with metal plates and screws. An osteotomy can be used for knee and hip arthritis, bunion surgery, and other surgical procedures.
