Abstract
Disclosed are an apparatus for an interspinous fixation and/or distraction of vertebrae and a methodology for minimally invasive implantation of the apparatus in the spine of a patient. The apparatus corresponds to a pair of teardrop shaped lateral wing elements spaced apart by a central core element that may be selectively sized during the implantation process. The wings and central core are held together by a single threaded bolt and locking nut configuration resulting in a simple structure that may be easily implanted with minimal patient discomfort.
