Intraoperative fluid management in complex lumbar spine surgery

Visual Analogue Scale (VAS) for leg and back pain, Oswestry Disability Index (ODI), all-cause reoperations and reoperations for reherniations over 2 years.Results: A total of 245 patients met the study criteria with 133 and 112 patients included in the control and treatment groups, respectively.Both groups had similar significant improvements in mean VAS and ODI scores at 2 years.During the 2-year postoperative period, 11.3% of the control group and 4.5% of the treatment group underwent reoperations (P ¼ 0.055).Unadjusted hazard ratio was 0.38 (95% CI: 0.14,1.06),representing a 62% reduction in reoperative risk for the treatment group with similar results after controlling for covariates.Cumulative risk of reoperation for recurrent herniation was significantly higher for the control versus the treatment group (9.8% vs. 0.9% respectively; P¼0.0032).There were no device placement complications or reoperations due to device migration or subsidence.Conclusion: Insertion of a strutted intradiscal spacer following discectomy in patients with lumbar herniation resulted in significantly decreased pain and disability at 2 years with a reduced rate of all-cause reoperations and significant reduction in operations for recurrent herniations compared to discectomy alone.
