    摘要: A surgical instrument for use in spinal surgery is provided. The surgical instrument may have particular application in posterior total disc arthroplasty. The surgical instrument is adapted to be minimally invasive. The surgical instrument can be anchored into position by a stability pin. Further, the surgical instrument can guide a chisel or other instrument to the intervertebral space to resect a portion of a vertebral endplate. In at least one embodiment, the surgical instrument is also capable of distracting the disc space.

    摘要: A spinal rod having first and second end members. The end members may be flexible or rigid. An expandable intermediate section is positioned between the first and second end members. The intermediate section may be axially expandable upon the introduction of a substance into a port that may be located in either of the first and second end members or the intermediate section. The intermediate section may be expandable between a first size, where the first and second end members are spaced a first distance apart, and a second enlarged size, where the first and second end members are spaced a second greater distance apart.

    摘要: The present application is directed to devices and methods for spacing apart spinous processes. In one embodiment, the device includes a body having a central portion that separates first and second sections. The body is constructed of a combination of an elastic material and a bio-absorbable material. When initially implanted within a patient, the bio-absorbable material affects the stiffness of the device. The device stiffness changes to that of the elastic material as the bio-absorbable material is absorbed by the body.
