Preoperative factors affecting the two-year postoperative patient-reported outcome in single-level lumbar grade I degenerative spondylolisthesis – Lumbar Fusion

Day Case Lumbar Fusion Surgery

The article investigates the factors that affect the patient-reported outcome in individuals with Meyerding grade I degenerative spondylolisthesis undergoing lumbar spinal stenosis surgery. The study included 72 patients who underwent minimally invasive decompression alone or with fusion. Patient-reported assessments and radiological evaluations were performed to assess the outcomes. The results showed that preoperative factors, such as L4 slippage (L4S) and lumbar axis sacral distance (LASD), significantly influenced the postoperative outcomes at 2 years. Patients with L4S of 6 mm or more had a lower rate of improvement in lumbar spine dysfunction, while those with a preoperative LASD of 30 mm or more had a higher rate of improvement. Multiple logistic analysis indicated that fusion surgery may be more advantageous for improving lumbar dysfunction in patients with a preoperative LASD of 30 mm or more

S: Preoperative L4S and LASD were extracted as significant preoperative factors affecting patient-reported outcomes at 2 years postoperatively. Multiple logistic analyses by the operative method suggested that DF may be advantageous in improving lumbar dysfunction due to low back pain in patients with preoperative LASD of 30 mm or more.

ABSTRACT

BACKGROUND: The choice of operative method for lumbar spinal stenosis with Meyerding grade I degenerative spondylolisthesis remains controversial. The purpose of this study was to identify the preoperative factors affecting the 2-year postoperative patient-reported outcome in Meyerding grade I degenerative spondylolisthesis.

METHODS: Seventy-two consecutive patients who had minimally invasive decompression alone (D group; 28) or with fusion (DF group; 44) were enrolled. The parameters investigated were the Japanese Orthopaedic Association back pain evaluation questionnaire as patient-reported assessment, and L4 slippage (L4S), lumbar lordosis (LL), and lumbar axis sacral distance (LASD) as an index of sagittal alignment for radiological evaluation. Data collected prospectively at 2 years postoperatively were examined by statistical analysis.

RESULTS: Sixty-two cases (D group; 25, DF group; 37) were finally evaluated. In multiple logistic regression analysis, preoperative L4S and LASD were extracted as significant preoperative factors affecting the 2-year postoperative outcome. Patients with preoperative L4S of 6 mm or more have a lower rate of improvement in lumbar spine dysfunction due to low back pain (risk ratio=0.188, p=.043). Patients with a preoperative LASD of 30 mm or more have a higher rate of improvement in lumbar dysfunction due to low back pain (risk ratio=11.48, p=.021). The results of multiple logistic analysis by operative method showed that there was a higher rate of improvement in lumbar spine dysfunction due to low back pain in patients with preoperative LASD of 30 mm or more in DF group (risk ratio=172.028, p=.01).

S: Preoperative L4S and LASD were extracted as significant preoperative factors affecting patient-reported outcomes at 2 years postoperatively. Multiple logistic analyses by the operative method suggested that DF may be advantageous in improving lumbar dysfunction due to low back pain in patients with preoperative LASD of 30 mm or more.
