Summary
Research Design: Retrospective cohort examine.
Aims: Describe the speed of dural tears (DTs) in grownup spinal deformity (ASD) surgical procedure. Describe the chance elements for DT and the influence of this complication on medical outcomes.
Strategies: Sufferers with ASD present process surgical procedure between 2008 and 2014 have been separated into DT and non-DT cohorts; demographics, operative particulars, radiographic, and medical outcomes have been in contrast. Statistical evaluation included t checks or ?2 checks as acceptable and a multivariate evaluation.
Outcomes: A complete of 564 sufferers have been recognized. The speed of DT was 10.eight% (n = 61). Sufferers with DT have been older (61.1 vs 56.5 years, P = .005) and have been extra more likely to have had prior backbone surgical procedure (odds ratio [OR] = 2.zero, 95% confidence interval [CI] = 1.2-Three.Three, P = .007). DT sufferers had larger pelvic tilt, decrease lumbar lordosis, and larger pelvic-incidence lumbar lordosis mismatch than non-DT sufferers (P < .05). DT sufferers had longer operative occasions (424 vs 375 minutes, P = .008), have been extra more likely to bear interbody fusions (OR = 2.zero, 95% CI = 1.1-Three.6, P = .021), osteotomies (OR = 2.2, 95% CI = 1.1-Four.zero, P = .012), and decompressions (OR = 2.Three, 95% CI = 1.Three-Four.Three, P = .003). In our multivariate evaluation, solely decompressions have been related to an elevated danger of DT (OR = Three.2, 95% CI = 1.Four-7.6, P = .006). There have been no important variations in affected person outcomes at 2 years.
Conclusions: The speed of DT was 10.eight% in an ASD cohort. That is much like charges of DT reported following surgical procedure for degenerative pathology. A historical past of prior backbone surgical procedure, decompression, interbody fusion, and osteotomies are all related to an elevated danger of DT, however decompression is the one unbiased danger issue for DT.
