Objective: Lumbar spinal stenosis (LSS) and degenerative spondylolisthesis (SL) are common. Patients without SL are often treated with surgical decompression (D), while those with SL Meyerding grade I frequently undergo decompression alone or in combination with stabilization (DS).

The purpose of this study was to examine the long-term results and quality of life of patients with LSS with and without SL having undergone surgery.

Method: In this retrospective, single-center study, 180 patients with LSS having undergone surgery between 2003 and 2010 were contacted for long-term follow-up including the Oswestry Disability Index (ODI), SF-12 and a questionnaire focusing on current symptoms. The questionnaires were completed either by mail or via telephone interview. For analysis, the patients were split into three groups: 115 patients without SL, 34 patients with SL having undergone only D and 31 patients with SL having undergone DS.

Results: The average age of the patients at the time of surgery was 66.6 ± 9.2 years and the average follow-up time 6.6 ± 2.3 years. Before surgery, 65 of the 180 patients had SL. Of the 34 patients treated by D alone, 29 had SL Meyerding grade I and 5 grade II. In the DS group, 21 had SL grade I and 10 grade II. At the time of follow-up, there were no statistically significant differences between the results of the ODI (without SL: 38.33 ± 22.96, SL and D: 32.71 ± 20.78, SL and DS: 35.38 ± 19.54), the SF-12 physical component summary scale (without SL: 33.19 ± 10.56, SL and D: 35.69 ± 11.06, SL and DS: 34.46 ± 10.11) and the SF-12 mental component summary scale (without SL: 46.19 ± 12.31, SL and D: 47.45 ± 14.06, SL and DS: 45.80 ± 13.34) of the three groups. In addition, walking distances, pain and sensory symptoms were similar between the three groups.

Conclusions: Our study suggests that the type of operation only has a minimal effect on the long-term results and quality of life of LSS patients, even in those with degenerative spondylolisthesis.
