    摘要: An artificial disc includes an intermediate section which is disposed between upper and lower retainers. The intermediate section includes a first portion which resists rotation of one of the retainers, for example, the upper retainer, from a first position to a second position. A second portion of the intermediate section of the artificial disc resists rotation of the upper retainer from the second position to a third position. The second portion of the intermediate section of the artificial disc is ineffective to provide significant resistance to relative rotation between the retainers during rotation of the upper retainer relative to the lower retainer from the first position to the second position. The artificial disc may be provided with projections which engage protrusions on the intermediate section to resist rotation of the upper retainer relative to the lower retainer from the second position to the third position.

    摘要: A method for replacing a spinal disc between first and second vertebrae of a spinal column includes determining a reference point on the spinal column. A marker is connected to a vertebra of the spinal column at the reference point. The marker is engaged with a guide assembly for guiding insertion of a surgical instrument between the first and second vertebrae to prepare the space between the first and second vertebrae for receiving an apparatus between the first and second vertebrae. The apparatus is inserted between the first and second vertebrae. The apparatus has a first end, a second opposite end, and first and second lateral sides extending between the first and second ends. An outer surface is engageable with the first vertebra of the spinal column. A rail extending from the outer surface is engageable with the first vertebra to connect the apparatus to the first vertebra. The rail extends a first distance from the outer surface adjacent the first end. The rail extends a second distance from the outer surface adjacent the second end. The second distance is greater than the first distance. A first projection extending from the outer surface is engageable with the first vertebra to connect the apparatus to the first vertebra. The first projection extends from the outer surface a first distance. A second projection extending from the outer surface is engageable with the first vertebra to connect the apparatus to the first vertebra. The second projection is located closer to the second end than the first projection. The second projection extends from the outer surface a second distance greater than the first distance. In another aspect of the apparatus, first and second rails extend from the outer surface. The first rail extends generally transverse to the first and second ends. The second rail extends generally transverse to the first rail.
