摘要： An intervertebral stabilization implant is described including an elongated central portion and a pair of reverse wings disposed at an angle of between 75.degree. and 80.degree. with respect to the elongated central portion of the implant. The method of utilizing the implant is also disclosed including exposing the pre-vertebral space as would be done in a Cloward's procedure. The vertebral disks below the luxating vertebra is widely resected, avoiding if at all possible the use of the intervertebral spreader. The A-P diameter of the vertebral bodies are measured and the intervertebral stabilizing implant of proper length is elected taking into account a small correction of the luxation of up to 2 millimeters maximum, which would upset the compression effect of the retaining wings over soft tissue and bone. The implant is inserted sideways, utlizing no force. After the posterior wing is barely in the canal it is rotated 90.degree. so that the posterior wing rests behind the lower vertebra and the superior or anterior wing is in front of the reduced vertebra.
