Abstract

The present invention provides a device and methodology for use in spinal fusion surgeries. An implant is proved for forming a rigid structure between adjoining vertebrae in a patient. The implant is a cage defined by at least a first end, second end, first side, and second side surface, wherein first and second side surfaces extend substantially parallel to each other to span a space between adjoining vertebrae and first and second ends interconnect said first side surface and second side surface. The cage incorporates one or more flexible joints that allow the cage to be deformed for insertion into a patient. The ability to deform the cage allows a greater ease and flexibility in inserting and positioning the implant.
