PG - 265-8 LID - 10.3171/2012.12.SPINE12805 [doi] AB - OBJECT: Although lumbar fusion is effective in well-selected patients, it is not without complications associated with short-term morbidity. There is a paucity of literature on the effect of these complications on long-term clinical outcomes. The purpose of this study was to determine whether perioperative complications-that is, those occurring within 30 days after surgery-alter the long-term clinical outcomes after lumbar fusion. METHODS: The authors retrospectively reviewed surgical and clinical databases for the period from 2001 to 2008 to identify patients who had undergone instrumented lumbar spinal fusion and had complete preoperative and 2-year postoperative outcome measures data. Outcome measures included the 36-Item Short-Form Health Survey (SF-36) Physical Component Summary, SF-36 Mental Component Summary, Oswestry Disability Index (ODI), and Numeric Rating Scales (0-10) for back and leg pain. Three patient groups were created for comparison-one with major complications, one with only minor complications, and another with no complications-using propensity matching techniques based on demographics, baseline clinical outcome scores, and surgical characteristics. Preoperative and 2-year postoperative outcome scores in the groups were compared. One-way ANOVA was used to compare continuous variables, and the Fisher exact test was used to compare categorical variables between the groups. Significance was set at p < 0.001. RESULTS: In the database with 1144 patients, 81 had a major complication. Of these 81 patients, 78 were propensity matched to a similar group of patients with minor complications and another group with no complications. Comparison of the 3 groups revealed that 2-year postoperative outcomes were not statistically different for any of the measures. Overall ODI at 2 years was better in patients having no complications (39.6) or only minor complications (37.0) than in those having major complications (44.5), but this difference was not statistically significant (p = 0.074). The proportion of patients reaching a minimum clinically important difference (MCID) for ODI was statistically significantly smaller in the major complication group (31%) than in the minor complication (51%) and no complication groups (65%; p < 0.001). CONCLUSIONS: A smaller proportion of patients achieved MCID for ODI 2 years after a major perioperative complication following lumbar fusion than after a minor complication or no complications.
