- PURPOSE: Satisfaction with the outcome of treatment is a widely used outcome measure but information about the determinants of patient satisfaction after surgery for central spinal stenosis (CSS) are lacking. The aim of the study was to analyze determinants of patient satisfaction 1 year after surgery for CSS without degenerative spondylolisthesis (DS).METHODS: This prospective register study included 5100 patients operated for CSS without DS. 88 % received decompression only (D) and 12 % had decompression and fusion (DF). The patient reported outcome measures were the EuroQol-5D, the Short-Form 36, the visual analogue scale for leg and back pain, the Oswestry disability index and the self-estimated walking distance. Logistic regression reporting odds ratios (OR) for being satisfied was utilized.RESULTS: There were significant baseline differences between satisfied and dissatisfied patients in all patient reported outcome measures except leg pain. Factors decreasing the likelihood for satisfaction included previous spine surgery OR: 0.4 (95 % CI: 0.3-0.5), smoking OR: 0.6 (95 % CI: 0.4-0.8), unemployment OR: 0.6 (95 % CI: 0.4-0.9), back pain exceeding 1 year OR: 0.6 (95 % CI: 0.4-0.9), back pain predominance OR: 0.7 (95 % CI: 0.5-0.8). Fusion surgery did not predict satisfaction OR: 1.3 (95 % CI: 0.9-1.9). Preoperative self-estimated walking distance >1000 m predicted satisfaction, OR: 2.4 (95 %: 1.6-3.6).CONCLUSIONS: Numerous factors have predictive value for satisfaction of outcome after surgery for CSS without DS. The results from this study can constitute background data in the shared decision making process when discussing surgery with patients suffering from CSS.

- BACKGROUND CONTEXT: Patients with spinal stenosis with concomitant degenerative spondylolisthesis (DS) and predominant back pain (PBP) have been shown to have inferior outcome after surgery. Studies comparing outcome according to preoperative pain predominance and treatment received are lacking.PURPOSE: The purpose was to study if adding spinal fusion to the decompression in DS affects outcome in patients with PBP (back pain [BP] Visual Analog Scale [VAS] more than or equal to leg pain [LP] VAS) compared with predominant leg pain (PLP) (BP VAS less than LP VAS).PATIENT SAMPLE: The Swedish Spine Register was used and included 1,624 patients operated for DS at the L4-L5 level.OUTCOME MEASURES: Self-reported measures were used, including a VAS for BP and LP, the EuroQol-5D (EQ-5D), and the physical and mental component summaries of the Short-Form 36 to estimate health-related quality of life and the Oswestry disability index (ODI) to estimate function.METHODS: Inclusion criterion was single-level DS operated on with either decompression only (D) or decompression and instrumented posterolateral fusion (DF). Based on preoperative LP and BP scores, the patients were assigned to one of the two groups: LP predominance or BP predominance. The patients completed the outcome protocol at 1- and 2-year follow-ups. Statistical analysis was performed using linear regression adjusting for multiple potential confounders.RESULTS: In the adjusted outcome at the 1-year follow-up, patients with PLP reported a 7.9-mm more improvement on the VAS for BP with fusion, compared with D (95% confidence interval [CI], 0.7-15.2), p=.03. Despite more change in the fused group, the reported BP levels remained similar in the D versus decompressed and fused at the 1-year follow-up (28 vs. 24, p=.77). The patients with PBP benefited from adding fusion in terms of BP 7.1 (95% CI, 0.3-13.9, p=.04), LP 8.8 (2-15.7, p=.01), the ODI 5.7 (1.6-9.9, p=.006), and the EQ-5D 0.09 (1.7-0.02, p=.02) at the 1-year follow-up as the DF group reported greater change in the outcome compared with the D group. At the 2-year follow-up, no significant differences were found between D and decompressed and fused in either the LP or the PBP groups.CONCLUSIONS: Patients with PBP operated with DF report better outcomes in terms of pain, function, and health-related quality of life than patients with D. Although these differences are significant on a group level, they may fail to reach minimal clinical significant difference. Patients with PLP report significantly more improvement in terms of BP with DF compared with D, but because of baseline differences in preoperative BP, these improvements may not be explained by the added fusion per se. At the 2-year follow-up, no significant differences were observed between the D and DF patients in either the PBP or PLP groups, but greater loss to follow-up in the DF groups could potentially bias these findings.
