摘要： An apparatus (10) promoting a spinal fusion between neighboring vertebrae (16, 18) is disclosed. Apparatus (10) may be located within the intervertebral disc space and preferably includes a pair of engaging plates (12, 14) for contacting the vertebrae (16, 18). An alignment device may be used to alter the vertical height (20) between the engaging plates (12, 14) to customize the apparatus (10) to fit a given patient. In one embodiment, the alignment device includes two turnbuckles (250, 270) and two pairs of cam blocks (260, 261; 280, 281) for adjusting the height between the engaging plates (202, 204). In another embodiment, the alignment device includes three turnbuckles (540, 550, 560) and three pairs of cam blocks (544, 545; 554, 555; 564, 565) for adjusting the height between the engaging plates (502, 504). In another embodiment, the alignment device includes three screws (640, 650, 660) and three cam blocks (644, 654, 664) for adjusting the height between the engaging plates (602, 604). In another embodiment, the alignment device includes four screws and four cam blocks for adjusting the height between the engaging plates. The alignment device may be adapted to vary the height (20) between the engaging plates (12, 14) such that the height of the apparatus (10) proximate the anterior end (22) is greater than that proximate the posterior end (24), whereby the natural lordosis of the spine is maintained after the apparatus (10) is installed, and such that the height (20) of the apparatus (10) proximate the first side edge (26) is substantially different from the height of the apparatus (10) proximate the second side edge (28), whereby the natural lateral alignment of the spine is maintained after the apparatus (10) is installed. In an alternate embodiment, the apparatus includes a single alignment device that may be used to alter the vertical distance between the engaging plates. The alignment device may include a turnbuckle and a single pair of cam blocks for adjusting the height between the engaging plates (12, 14).

摘要： An instrumentation set may include insertion instruments for forming an implant between bone structures. The insertion instruments may include a spreader (400) and a separator (300). The bone structures may be vertebrae. Implant members (12) may be attached to the spreader and positioned between the bone structures. The separator may be inserted into the spreader to establish a desired separation distance between the implant members. Connectors (14) may be inserted into the implant members to join the implant members together and form the implant. The insertion instruments may be removed. A seater (1100) may be used to set the position of the connectors relative to the implant members to inhibit disassembly of the implant.

摘要： A spinal stabilization system may include a pair of structural members coupled to at least a portion of a human vertebra with connectors. Connectors may couple structural members to spinous processes. Some embodiments of a spinal stabilization system may include fasteners that couple structural members to vertebrae. In some embodiments, a spinal stabilization system provides three points of fixation for a single vertebral level. A fastener may fixate a facet joint between adjacent vertebrae and couple a stabilization structural member to a vertebra. Connectors may couple the structural members to the spinous processes of the vertebrae. Use of a spinal stabilization system may improve the stability of a weakened or damaged portion of a spine. When used in conjunction with an implant or other device, the spinal stabilization system may immobilize vertebrae and allow for fusion of the implant or other device with vertebrae.
