Predictors of the Best Outcomes Following Minimally Invasive Surgery for Grade 1 Degenerative Lumbar Spondylolisthesis

Abstract INTRODUCTION The factors driving the best outcomes following minimally invasive surgery (MIS) for degenerative lumbar spondylolisthesis (DLS) are not clearly elucidated. This study investigates the factors that drive the best patient reported outcomes (PRO) following MIS for DLS. METHODS A total of 608 patients from the prospective Quality Outcomes Database (QOD) Lumbar Spondylolisthesis Registry underwent surgery for grade 1 DLS of whom 259 underwent surgery with MIS techniques [187 fusions (72.2%)]. Surgeries were classified as MIS if any of the following were involved: MIS laminectomy, MIS pedicle screws, MIS interbody grafts, or percutaneous screws. Outcomes were assessed at 24 mo postoperatively. PROs included the Oswestry Disability Index (ODI), numeric rating scale (NRS) Back Pain, NRS Leg Pain, EuroQoL-5D (EQ-5D) Questionnaire, and North American Spine Society (NASS) Satisfaction Questionnaire. Multivariate models were constructed adjusting for patient characteristics, presentation characteristics, surgical variables, socioeconomic characteristics, and baseline PRO values. RESULTS The mean age of the MIS cohort was 64.2 ± 11.5 yr [148 (57.1%) women and 111 (42.9%) men]. In multivariate analyses, aside from baseline PRO values, only 3 factors were significantly associated with multiple 24-mo PRO change scores: employment, age, and the addition of fusion to surgery. Employment was associated with superior postoperative ODI (ß-7.8; 95% CI [−12.9- −2.6]; P = .003), NRS back pain (ß-1.2; 95% CI [−2.1- −0.4]; P = 0.004), EQ-5D (ß0.1; 95% CI [0.01-0.1]; P = .03), and NASS satisfaction (OR = 0.27; 95% CI [0.12-0.58]; P < .001). Increasing age was associated with superior NRS leg pain (ß-0.1; 95% CI [minus;0.1- minus;0.01]; P = .03) and NASS satisfaction (OR = 0.95; 95% CI [0.92-0.99]; P = .02). The addition of a fusion was associated with superior ODI (ß-6.7; 95% CI [minus;12.7- minus;0.7]; P = .03), NRS back pain (ß-1.1; 95% CI [minus;2.1- minus;0.2]; P = .02), and NASS satisfaction (OR = 0.28; 95% CI [0.12-0.62]; P = .002). CONCLUSION Preoperative active employment, at least 4 yr of college education, and surgeries including a fusion were significant predictors of superior outcomes across the domains of disease-specific disability, back pain, leg pain, quality of life, and patient satisfaction. Increasing age was predictive of superior outcomes for leg pain and satisfaction.

Abstract BACKGROUND The factors driving the best outcomes following minimally invasive surgery (MIS) for grade 1 degenerative lumbar spondylolisthesis are not clearly elucidated. OBJECTIVE To investigate the factors that drive the best 24-mo patient-reported outcomes (PRO) following MIS surgery for grade 1 degenerative lumbar spondylolisthesis. METHODS A total of 259 patients from the Quality Outcomes Database lumbar spondylolisthesis module underwent single-level surgery for degenerative grade 1 lumbar spondylolisthesis with MIS techniques (188 fusions, 72.6%). Twenty-four-month follow-up PROs were collected and included the Oswestry disability index (ODI) change (ie, 24-mo minus baseline value), numeric rating scale (NRS) back pain change, NRS leg pain change, EuroQoL-5D (EQ-5D) questionnaire change, and North American Spine Society (NASS) satisfaction questionnaire. Multivariable models were constructed to identify predictors of PRO change. RESULTS The mean age was 64.2 ± 11.5 yr and consisted of 148 (57.1%) women and 111 (42.9%) men. In multivariable analyses, employment was associated with superior postoperative ODI change (β-7.8; 95% CI [−12.9 to −2.6]; P = .003), NRS back pain change (β −1.2; 95% CI [−2.1 to −0.4]; P = .004), EQ-5D change (β 0.1; 95% CI [0.01-0.1]; P = .03), and NASS satisfaction (OR = 3.7; 95% CI [1.7-8.3]; P < .001). Increasing age was associated with superior NRS leg pain change (β −0.1; 95% CI [−0.1 to −0.01]; P = .03) and NASS satisfaction (OR = 1.05; 95% CI [1.01-1.09]; P = .02). Fusion surgeries were associated with superior ODI change (β −6.7; 95% CI [−12.7 to −0.7]; P = .03), NRS back pain change (β −1.1; 95% CI [−2.1 to −0.2]; P = .02), and NASS satisfaction (OR = 3.6; 95% CI [1.6-8.3]; P = .002). CONCLUSION Preoperative employment and surgeries, including a fusion, were predictors of superior outcomes across the domains of disease-specific disability, back pain, leg pain, quality of life, and patient satisfaction. Increasing age was predictive of superior outcomes for leg pain improvement and satisfaction.

Objective: To explore the clinical effect of the application of CT navigation in the treatment of lumbar spondylolisthesis with minimally invasive surgery - transforaminal lumbar interbody fusion (MIS-TLIF). Methods: A retrospective study was conducted on 30 patients with lumbar spondylolisthesis who were continuously treated in linyi central hospital from May 2018 to March 2019.The patients were divided into two groups,15 patients treated with MIS-TLIF with the aid of CT navigation during the operation were included into an observation group. Another 15 patients were treated with open transforaminal lumbar interbody fusion as the control group. The baseline information, including gender, age and course of disease, perioperative period and imaging conditions, and VAS and ODI scores of patients in the two groups were collected and analyzed. Results: Fifteen patients were included into the observation group, including 9 male and 6 female patients with an average age of 52.60 ± 6.31 and a course of disease of 16.33 ± 6.00 months. The other 15 patients were included into the observation group, including seven male and eight female patients with an average age of 52.87 ± 7.38 and a course of disease of 19.13 ± 9.89 months. The difference in the gender, age and course of disease between the two groups had no statistical significance (P > 0.05). However, the difference in the duration of operation and intraoperative blood loss between the two groups had statistical significance (P< 0.05). There were no statistically significant differences in wound complications, neurological complications, preoperative slippage rate, postoperative slippage rate, slippage reduction rate and screw placement accuracy (P > 0.05). VAS scores of the two groups were statistically significant from six months after surgery (P < 0.01). There was no significant difference in ODI between the two groups at any time point (P >0.05). VAS and ODI scores were improved at each time point compared with those before surgery. Conclusion: The minimally invasive transforaminal lumbar fusion performed with the aid of CT navigation during the operation shortens the duration of operation and the amount of bleeding, reduces the back pain, is beneficial to the early postoperative functional exercise, and speeds up the postoperative recovery. doi: https://doi.org/10.12669/pjms.36.5.2341 How to cite this:Sui RD, Wang CG, Zhang JC, Wang HT.
