Targets: Lumbosacral fusion by both an anterior or a posterior method to realize good lordosis and stability is at all times a difficult surgical treatment and is commonly accompanied by the next price of pseudarthrosis than when different lumbar segments are concerned. This research evaluated the medical and radiological outcomes of lumbosacral fusions achieved by a mixed anterior and posterior method.
Supplies and Strategies: From June 2008 to 2012, 20 sufferers who had L5-S1 instability and stenosis have been consecutively handled, first by anterior interbody fusion utilizing an allogenous strut bone graft by the pararectus method after which by posterior pedicle screw fixation. A minimal of 1-year of medical and radiological follow-up was performed. Intraoperative blood loss, surgical time, and any surgery-related problems have been recorded. Scientific outcomes have been assessed utilizing a visible analog scale (VAS) and the affected person’s Oswestry Incapacity Index (ODI) rating. After 1 12 months, radiological outcomes have been assessed by analyzing pelvic incidence, lumbar lordosis, and segmental lordosis utilizing static plain movies, whereas fusion stability was assessed utilizing dynamic plain movies.
Outcomes: The imply operative time and blood loss have been 215 min and 325 cc, respectively. After 1 12 months, the VAS and ODI scores had considerably improved, and secure fusion with good lordotic curvature was obtained in all instances.
Conclusion: The surgical outcomes of the mixed process are passable by way of the useful and radiological outcomes. Our methodology gives benefits concerning each anterior fusion and posterior fixation.
