  • STUDY DESIGN: A prospective cohort study of consecutive patients. OBJECTIVE: Determination of the quality of life (QoL) and prevalence of slip progression in patients with degenerative lumbar spondylolisthesis managed nonoperatively. SUMMARY OF BACKGROUND DATA: Lumbar spinal stenosis secondary to degenerative lumbar spondylolisthesis is a common radiographic diagnosis associated with chronic back pain and radicular symptoms. There is limited evidence as to the clinical course in terms of validated QoL measures, and the extent of slip progression in patients with this condition treated nonoperatively. METHODS: Validated disease-specific and generic QoL metrics including SF12 physical and mental scores [SF12-physical component summary (PCS) and SF12-mental component summary (MCS)], Oswestry Disability Index (ODI), and numeric scales for back and leg pain as well as radiographic assessment of slip extent were evaluated at initial consultation (baseline) and at a minimum of 5 years after the baseline assessment. Slip progression was defined by a >5% increase in slip percentage. RESULTS: Thirty-nine of 160 (24.4%) patients elected to switch to operative management, despite no slip progression on preoperative radiographs. Seventy spondylolisthetic levels in 66 participants were assessed after a minimum of 5 years of nonoperative management. Twenty-one participants (31.8%) had slip progression. SF12-PCS, ODI, and leg pain improved similarly in both groups (P < 0.05). SF12-MCS did not change significantly in either group. Back pain improved only in the nonprogressing group. CONCLUSION: The majority of cases of low-grade spondylolisthesis do not progress over 5 years with nonoperative management. Regardless of whether there was progression or not, the mean PCS, ODI, and leg pain improved from baseline, although symptoms remained and a significant number elected to switch to surgical management before 5 years. Back pain improved with nonoperative treatment only in those without progression. LEVEL OF EVIDENCE: 2.
