Minimally invasive lateral intervertebral fixation system

摘要

A system, device and method are disclosed for minimally invasive lateral intervertebral fixation. An intervertebral fixation device (1102) includes a weight-bearing shell (101) configured to fit into a disk space between plural vertebrae, the weight-bearing shell including a keyway opening (119) between and through plural sidewalls (102, 104). A first plurality of anchors (610-616) is rotatably disposed in a first orientation in relation to the weight-bearing shell (101). A second plurality of anchors (602-608) is rotatably disposed in a second orientation in relation to the weight-bearing shell (101). A key (704) is adapted to rotate the first plurality of anchors (610-616) in divergent directions from the second plurality of anchors (602-608) and to secure a first vertebra and a second vertebra, respectively. The key (704) is further adapted to support the first plurality of anchors (610-616) and the second plurality of anchors (602-608) in divergent directions in relation to the weight-bearing shell (101), the first plurality of anchors and the second plurality of anchors secured to the first vertebra and the second vertebra.
