METHODS AND APPARATUS FOR MINIMALLY INVASIVE MODULAR INTERBODY FUSION DEVICES

摘要

The invention is a minimally invasive modular interbody fusion device for fusing adjacent spinal vertebrae The device includes a first modular segment having a width including a first rail extending along one side of the width and beyond a periphery of a body portion of the first modular segment. A second modular segment slidably connected to the first rail on one side of the width and having a second rail extending at least partially along another side of the width and beyond a periphery of a body portion of the second modular segment. A third modular segment slidably connected to the second rail on one side The modular segments can be extended and are positioned in a generally side by side configuration that defines a unitary body that mimics the planar shape of the vertebra such that the device contacts and supports the adjacent vertebra.
