Minimally invasive spine surgery is surgery performed using the least invasive techniques and minimal incisions possible to access the spine. This can involve special instruments and implants designed to be delivered through that least invasive opening. Traditional spine surgery involves long, deep cuts through muscles, which can leave long scars and require an extended amount of healing time.

In minimally invasive spine surgery, a small incision is made. A series of tubular dilators is then inserted in order to widen the opening to grant surgeons access to the area with minimal damage to muscle tissue. Because the muscle tissue is spread apart, it is able to close back after surgery is complete. This means less scarring and a faster recovery time than traditional spine surgery. The surgeon then works through the tubes, using special tools to perform the surgery.
