Leadership begins before the patient enters the surgical theater, among the spine care professionals that form the coAlliance. This may be a small yet vital observation, a critical instrument change, an entirely new surgical method, or a decade-long quest for biomaterials that improve implant performance. From such leadership emerge coLigne spine treatment technologies, each with its impact upon our field. Providing spine treatment technologies to the world is coLigne’s business. Equipping spine surgeons to improve their art is coLigne’s passion and our way of life.
