[Minimally invasive percutaneous transpedicular lumbar spine fixation. Operative technique and a case report]

Transpedicular fixation systems are commonly used in lumbar spine surgery for the treatment of a variety of pathologies making the solid fusion of operated spinal segments possible. Recently there has been a big interest in minimally invasive techniques in spinal surgery, including minimally invasive fixation systems. By minimizing the operative trauma minimally invasive techniques allow patients to restore activity faster. In the paper the authors present the Sextant system (Medtronic Sofamor Danek), which provides minimally invasive (percutaneous) fixation. Before fixing the spine, it is necessary to perform discectomy and interbody fusion using the PLIF or ALIF method. The authors present the system, describe the operative technique, and present a case of the patient with L4/L5 spondylolisthesis successfully treated using this technique.
