Cortical Bone Trajectory Screws in Posterior Lumbar Interbody Fusion: Minimally Invasive Surgery for Maximal Muscle Sparing—A Prospective Comparative Study with the Traditional Open Technique

Abstract: Introduction A prospective comparative study between classical posterior interbody fusion with peduncular screws and the new technique with divergent cortical screws was conducted. Material and Methods Only patients with monosegmental degenerative disease were recruited into this study. We analyzed a cohort of 40 patients treated from January 2015 to March 2016 divided into 2 groups (20 patients went to traditional open surgery and 20 patients under mini-invasive strategy). Primary endpoints of this study are … Show more

“…The results were consistent with that in similar cohorts [31]. The average surgical time ranged from 117.8min to 237.6min [8,20], and 119ml to 276.5ml [21,32] for intraoperative blood loss in previous studies of single level cortical screw fixation surgery [21,[32][33][34].…”

“…Moreover, they have been demonstrated to have a superior fixation strength and good stiffness in flexion and extension. 8,11,[34][35][36][37] This technical note and case series is, to our knowledge, the first clinical description on the use of a patient-matched guide for posterior CBT screw placement. Only cadaveric studies have existed until now.…”

“…Regarding long-term outcomes, there has not been any validated data, but good expectations are generally anticipated, as suggested by several studies. [6][7][8][9][10][11][12] Accurate screw placement in spinal surgery has always been a challenge for surgeons. Many technologies and useful tools have been developed in recent years, including fluoroscopy, navigation software, electrical conductivityebased systems, neuromonitoring, and custom-made template guides.…”

“…Increased blood loss during lumbar fixation has been correlated with increased muscle damage. 18 Another theoretical advantage of decreased blood loss is a subsequent decreased risk of blood transfusion and other complications in patients with comorbid conditions who are more sensitive to lower postoperative hemoglobin levels. Indeed, no patients in the CBT group required a postoperative blood transfusion.…”
