摘要：
A method of using an interbody spinal implant by implanting the spinal implant into a patient in need of the spinal implant. The method includes accessing the disc space of the patient and locating the center of the disc space. The disc space is incised by making a window in the annulus of the disc space for insertion of the spinal implant. The endplates are cleaned of all cartilage and the disc structure, which is encapsulated by the annulus, is removed while avoiding damage to the endplate structure of the vertebrae. Optionally a size-specific rasp is selected and the disc space is cleared of all soft tissue and cartilage. Optionally the disc space is distracted by sequentially expanding it with distractors of progressively increasing heights. A spinal implant having a pre-determined size sufficient to balance frictional fit and elongation of the annulus is selected and seated in the disc space.
