Multicenter Study Observational StudyMinimal access spinal technologies (MAST) fusion procedures for the treatment of the degenerative lumbar spine (a part of multicentral prospective study). Case Report.
A prospective multicentral observational study of minimally invasive fusion to treat degenerative lumbar disorders, and to report outcomes of one or two level minimally invasive posterior lumbar interbody fusion (MLIF) for degenerative lumbar disorders in a multi-center 1-year prospective study. We prospectively studied a group of 32 patients, mostly female 24 (75% female), and 8 males (25%). They underwent minimally invasive transforaminal lumbar interbody fusion (mTLIF), 21 of them monosegmental and 11 bisegmental. ⋯ Mean surgical duration, blood loss and intraoperative fluoroscopy time were 125 vs. 175 minutes, 150 vs. 170 ml, and 105 vs. 145 seconds in one- and two-level segments, respectively. Mean preoperative VAS back (6.5) and VAS leg (7.9) scores dropped significantly (p<0.0001) to 3.5 (2.6) and 2.6 (2.0) at discharge (6 weeks). At the end, this is the largest prospective multi-center observational study of MLIF to date, following routine local standard of practice and, MLIF demonstrated favourable clinical results with early and sustained improvement in patient reported outcomes and low major perioperative morbidity.
