“…Postoperative spinal computed tomographic or magnetic resonance imaging scans to assess surgery-induced spinal instability and the amount of bone removal were not performed routinely. However, it is known that the degree of radiologically confirmed decompression and evidence of instability are poorly related to the surgical outcome (6,9,10). The general composition, demographics, signs, symptoms, and surgical details in our patient population are comparable with those reported previously (1-4, 6-21, 23-26, 28-35).…”

Study Design Retrospective subgroup analysis of prospectively collected data according to treatment received. Objective The purpose of this study is to determine if the duration of symptoms affects outcomes following the treatment of spinal stenosis (SS) or degenerative spondylolisthesis (DS). Summary of Background Data The Spine Outcomes Research Trial (SPORT) study was designed to provide scientific evidence on the effectiveness of spinal surgery versus a variety of non-operative treatments. Methods An as-treated analysis was performed on patients enrolled in the Spine Patient Outcomes Research Trial (SPORT) for the treatment of SS or DS. A comparison was made between patients with SS with ≤12 months (n=405) and those with >12 months (n=227) duration of symptoms. A comparison was also made between patients with DS with ≤12 months (n=397) and those with >12 months (n=204) duration of symptoms. Baseline patient characteristics were documented. Primary and secondary outcomes were measured at baseline and at regular follow-up time intervals up to 4 years. The difference in improvement among patients whose surgical or nonsurgical treatment began less than or greater than 12 months after the onset of symptoms was measured. In addition, the difference in improvement with surgical versus nonsurgical treatment (treatment effect) was determined at each follow-period for each group. Results At final followup, there was significantly less improvement in primary outcome measures in SS patients with >12 months symptom duration. Primary and secondary outcome measures within the DS group did not differ according to symptom duration. There were no statistically significant differences in treatment effect of surgery in SS or DS patients. Conclusions Patients with spinal stenosis with fewer than twelve months of symptoms experienced significantly better outcomes with surgical and nonsurgical treatment relative to those with symptom duration greater than twelve months. There was no difference in outcome of patients with degenerative spondylolisthesis according to symptom duration.

“…Interestingly, of the pain-related measures, only the Oswestry disability score was associated with depression. The Oswestry disability score [37,38] has been found to correlate with VAS pain assessments [56], and also a very strong correlation has been demonstrated between Oswestry scores and LSS patients' perception of improvement after surgery [57,58]. The Oswestry disability score seems to be a sensitive method for the detection of the subjective disability and the sense of everyday functioning of LSS patients.…”

Long-Term Clinical and Magnetic Resonance Imaging Follow-Up Assessment of Patients With Lumbar Spinal Stenosis After Laminectomy

Abstract: Patients' perception of improvement had a much stronger correlation with long-term surgical outcome than structural findings seen on postoperation magnetic resonance imaging. Moreover, degenerative findings had a greater effect on patients' walking capacity than stenotic findings.
