Abstract
Objective:To evaluate a method to reduce high degree spondylolisthesis in adults with monosegmental fixing preserving the adjacent level and the improvement of sagittal balance.Methods:A prospective study, with 12 adult patients with high degree spondylolisthesis (III and IV) in adults who underwent surgery by the same team. We included 7 women and 5 men with a mean age of 37 years and lombosciatalgy that had no improvement with conservative treatment. The surgical technique used was total or partial reduction by Spondylolisthesis Reduction Instrument (SRI) system, with instrumentation only in the affected level, thus sparing the adjacent level, associated with 360ofusion.Results:The L5-S1 level was involved in nine patients, L4-L5 in two, and VT-S1 in one patient. The isthmic type predominated in nine patients, followed by dysplastic type in two, and one iatrogenic spondylolisthesis. These patients were assessed by the Oswestry scale, which showed a preoperative average of 59% and postoperative average of 12.4% (P<0.05). A significant improvement in the average slip angle from 54.66% to 9.5% (35% to 0%) was found. No major complications such as infection, neurological damage or material breaks were observed.Conclusion:The reduction of high degree listhesis instrumenting only the affected level produces good results, with good control of pain and functional improvement of patients. However, a larger follow-up is required to better evaluation.
