Abstract
An implant for intersomatic fusion of two adjacent vertebrae has a web plate and a pair of arms extending from ends of the web plate and imparting a U-shape to the implant. The arms forming with the web plate a space. Such implants are used to stabilize two adjacent vertebrae following resection of a disk between them and distraction of the two vertebrae to form between confronting faces of the vertebrae a gap through which the patient's spinal chord extends. The implants are inserted into the gap from the posterior to each side of the spinal chord and then the spaces defined between the arms are packed with bone chips. Such a procedure is, by comparison with the standard anterior approach, relatively noninvasive and therefore is much less expensive and difficult for the patient.
