SP-Fix® is a spinous process fixation device designed to provide structural stability, indirect decompression and immobilization of the spinous processes of adjacent vertebrae. SP-Fix® is implanted using a minimally invasive approach and preserves the supraspinous ligament. SP-Fix® offers surgeons an easy-to-use system that helps preserve patient anatomy. SP-Fix® is not a stand-alone device and requires additional fixation.
