Abstract
BackgroundPercutaneous pedicle screw technique is relatively a recent technique that evolved the concept of posterior spinal instrumentation, utilizing familiar fluoroscopic landmarks to guide the procedure of screws insertion, which despite being technically demanding, it avoids the Musculo-ligamentous damage associated with the conventional posterior technique.Aim of the workThis study aims to report our experience in managing traumatic and degenerative spine pathologies by the minimally invasive percutaneous technique and assessing its radiological and functional outcome.Materials and methodsA prospective observational study that included the analysis of the functional, operative, biochemical, and radiological outcomes of 20 patients who underwent uniplanar fluoroscopic-guided dorsal and/or lumbar percutaneous pedicle screw fixation procedures with or without fusion using the sextant, longitude, and Spineart system and any reported complications between January 2018 and December 2019.ResultsThe clinical and radiological analysis of 100 percutaneous pedicle screws in degenerative (n:11) and traumatic (n:9) dorsal and/or lumbar cases revealed that the biomechanical stabilizing characteristics are comparable to the conventional posterior approach with the added benefits of the paraspinal muscle-sparing. Satisfactory functional outcome represented in the improvement of the postoperative back pain visual analog score and Oswestry Disability Index Score with acceptable morbidity and complications rate was noticed.ConclusionsPercutanous pedicle screw fixation is a landmark in the evolution of the minimally invasive spine surgery which can be a safe alternative to the conventional posterior muscle stripping technique with a comparable functional and radiological outcome and good biomechanical profile and an acceptable morbidity rate.
Highlights
Percutaneous pedicle screws are a relatively recent minimally invasive spine technique which was first innovated by Magerl et al [1] in 1977 for the external fixation of the spine in the patients who required transient stability forFoley et al [3] evolved the concept into an internal fixation technique which preserved the minimally invasive nature and the biomechanical properties of the external fixation systems, while avoiding its temporary nature and the associated high infection rate
Since the development of the Medtronic sextant system used by Foley in 2000, many percutaneous fixation systems were developed to address more complex spinal pathologies while enhancing the surgeon feedback by the integration of recent technological feats as intraoperative computed topography (CT), robotic surgery, and neuronavigational modules that compensate for the loss of direct visualization of the anatomical landmarks [4]
This study aims for assessing the operative, radiological, and functional outcome of 20 patients who had been operated by three different systems (Medtronic sextant, Medtronic longitude, and Spineart ROMEO 2 Minimally invasive surgery (MIS)) for various degenerative and traumatic spinal pathologies using uniplanar fluoroscopy in a developing country educational institute
