OBJECT: Lumbar discectomy is the most common surgical procedure performed in the US for @entity1 experiencing back and @entity158 from @entity890 . However, not all @entity1 will benefit from lumbar discectomy. @entity1 with certain psychological predispositions may be especially vulnerable to poor clinical outcomes. The goal of this study was therefore to determine the role that preoperative @entity308 and somatic @entity148 have on long-term back and @entity158 , disability, and quality of life (QOL) for @entity1 undergoing single-level lumbar discectomy. METHODS: In 67 adults undergoing discectomy for a single-level @entity890 , the authors determined quantitative measurements of @entity615 (visual analog scale [VAS]), quality of life (36-Item Short Form Health Survey [SF-36]), and disease-specific disability ( @entity717 Index) preoperatively and at 6 weeks, 3, 6, and 12 months after surgery. The degree of preoperative @entity308 and @entity2531 was assessed using the Zung Self-Rating @entity308 Scale and a modified somatic perception questionnaire (MSPQ). Multivariate regression analyses were performed to assess associations between Zung Scale and MSPQ scores with achievement of a @entity922 ( @entity922 ) in each outcome measure by 12 months postoperatively. RESULTS: All @entity1 completed 12 months of follow-up. Overall, a significant improvement in VAS @entity158 , @entity615 , @entity717 Index, and SF-36 Physical Component Summary scores was observed by 6 weeks after surgery. Improvements in all outcomes were maintained throughout the 12-month follow-up period. Increasing preoperative @entity308 (measured using the Zung Scale) was associated with a decreased likelihood of achieving an @entity922 in disability (p = 0.006) and QOL (p = 0.04) but was not associated with VAS @entity158 (p = 0.96) or back @entity158 (p = 0.85) by 12 months. Increasing preoperative somatic @entity148 (measured using the MSPQ) was associated with decreased likelihood of achieving an @entity922 in disability (p = 0.002) and QOL (p = 0.03) but was not associated with @entity158 (p = 0.64) or back @entity158 (p = 0.77) by 12 months. CONCLUSIONS: The Zung Scale and MSPQ are valuable tools for stratifying risk in @entity1 who may not experience clinically relevant improvement in disability and QOL after discectomy. Efforts to address these confounding and underlying contributors of @entity308 and heightened somatic @entity148 may improve overall outcomes after lumbar discectomy.
