Minimally Invasive Decompression

Abstract BACKGROUND: Decompression without fusion is a treatment option in patients with lumbar spinal stenosis (LSS) associated with stable low-grade degenerative spondylolisthesis (DS). A minimally invasive unilateral laminotomy (MIL) for “over the top” decompression might be a less destabilizing alternative to traditional open laminectomy (OL). OBJECTIVE: To review secondary fusion rates after open vs minimally invasive decompression surgery. METHODS: We performed a literature search in Pubmed/MEDLINE using the keywords “lumbar spondylolisthesis” and “decompression surgery.” All studies that separately reported the outcome of patients with LSS+DS that were treated by OL or MIL (transmuscular or subperiosteal route) were included in our systematic review and meta-analysis. The primary end point was secondary fusion rate. Secondary end points were total reoperation rate, postoperative progression of listhetic slip, and patient satisfaction. RESULTS: We identified 37 studies (19 with OL, 18 with MIL), with a total of 1156 patients, that were published between 1983 and 2015. The studies’ evidence was mostly level 3 or 4. Secondary fusion rates were 12.8% after OL and 3.3% after MIL; the total reoperation rates were 16.3% after OL and 5.8% after MIL. In the OL cohort, 72% of the studies reported a slip progression compared to 0% in the MIL cohort, respectively. After OL, satisfactory outcome was 62.7% compared to 76% after MIL. CONCLUSION: In patients with LSS and DS, minimally invasive decompression is associated with lower reoperation and fusion rates, less slip progression, and greater patient satisfaction than open surgery.

ABSTRACT BACKGROUND It remains unclear if minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) is comparable to traditional, open TLIF because of the limitations of the prior small-sample-size, single-center studies reporting comparative effectiveness. OBJECTIVE To compare MI-TLIF to traditional, open TLIF for grade 1 degenerative lumbar spondylolisthesis in the largest study to date by sample size. METHODS We utilized the prospective Quality Outcomes Database registry and queried patients with grade 1 degenerative lumbar spondylolisthesis who underwent single-segment surgery with MI- or open TLIF methods. Outcomes were compared 24 mo postoperatively. RESULTS A total of 297 patients were included: 72 (24.2%) MI-TLIF and 225 (75.8%) open TLIF. MI-TLIF surgeries had lower mean body mass indexes (29.5 ± 5.1 vs 31.3 ± 7.0, P = .0497) and more worker's compensation cases (11.1% vs 1.3%, P < .001) but were otherwise similar. MI-TLIF had less blood loss (108.8 ± 85.6 vs 299.6 ± 242.2 mL, P < .001), longer operations (228.2 ± 111.5 vs 189.6 ± 66.5 min, P < .001), and a higher return-to-work (RTW) rate (100% vs 80%, P = .02). Both cohorts improved significantly from baseline for 24-mo Oswestry Disability Index (ODI), Numeric Rating Scale back pain (NRS-BP), NRS leg pain (NRS-LP), and Euro-Qol-5 dimension (EQ-5D) (P > .001). In multivariable adjusted analyses, MI-TLIF was associated with lower ODI (β = −4.7; 95% CI = −9.3 to −0.04; P = .048), higher EQ-5D (β = 0.06; 95% CI = 0.01-0.11; P = .02), and higher satisfaction (odds ratio for North American Spine Society [NASS] 1/2 = 3.9; 95% CI = 1.4-14.3; P = .02). Though trends favoring MI-TLIF were evident for NRS-BP (P = .06), NRS-LP (P = .07), and reoperation rate (P = .13), these results did not reach statistical significance. CONCLUSION For single-level grade 1 degenerative lumbar spondylolisthesis, MI-TLIF was associated with less disability, higher quality of life, and higher patient satisfaction compared with traditional, open TLIF. MI-TLIF was associated with higher rates of RTW, less blood loss, but longer operative times. Though we utilized multivariable adjusted analyses, these findings may be susceptible to selection bias.

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 &lt; .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.

Abstract INTRODUCTION Here, we compare minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) to traditional, open TLIF for grade 1 degenerative lumbar spondylolisthesis in the largest study to date by sample size. METHODS We utilized the multicenter, prospective Quality Outcomes Database registry and queried patients with grade 1 degenerative lumbar spondylolisthesis who underwent single-segment surgery with fully minimally invasive or open TLIF methods. Outcomes were compared 24 mo postoperatively: Oswestry Disability Index (ODI), Numeric Rating Scale Back Pain (NRS-BP), NRS Leg Pain (NRS-LP), EuroQol-5D (EQ-5D), North American Spine Society (NASS) Satisfaction Score, cumulative reoperation rate, and return to work (RTW) rate. Multivariate analyses were utilized to adjust for variables reaching P < .20 on univariate analyses. RESULTS A total of 297 patients were included: 72 (24.2%) MI-TLIF and 225 (75.8%) open TLIF. Average age (MI-TLIF: 62.1 vs open TLIF: 59.5 yr) was similar (P = .10). MI-TLIF surgeries were associated with lower body mass index (29.5 ± 5.1 vs 31.3 ± 7.0, P = .0497) and more workman's compensation cases (11.1% vs 1.3%, P = .001). Patients did not differ significantly at baseline for ODI, NRS BP, NRS LP and EQ-5D (P > .05). MI-TLIF was associated with less blood loss (108.8 ± 85.6 vs 299.6 ± 242.2 mL, P < .001), longer operations (228.2 ± 111.5 vs 189.6 ± 66.5 min, P < .001), and a trend toward decreased length of hospitalization (2.9 ± 1.8 vs 3.3 ± 1.6 d, P = 0.08). Discharge disposition to home or home healthcare was similar (94.4% vs 91.1%, P = .38). Both cohorts improved significantly from baseline for 24-month ODI, NRS-BP, NRS-LP, and EQ-5D (P > .001). In adjusted analyses, MI-TLIF was associated with superior ODI (ß = −4.7; 95% CI-9.3 −0.04; P = .048) and EQ-5D (ß = 0.06; 95% CI 0.009-0.11; P = .02). Though trends for superiority were evident for MI-TLIF, they did not reach statistical significance for NRS-BP (P = .06), NRS-LP (P = .07), and NASS Satisfaction (P = .06). Similarly, there was a trend for fewer reoperations following MI-TLIF, though this did not reach statistical significance (1.4% vs 7.6%, P = .10). A higher proportion of MI-TLIF patients were able to RTW following surgery (100% vs 80%, P = .02). CONCLUSION For single-level grade 1 degenerative lumbar spondylolisthesis, MI-TLIF was associated with superior outcomes for disability and quality of life compared with traditional, open TLIF. MI-TLIF was associated with higher rates of RTW and less blood loss, but longer operative times.
