Study Design: Retrospective cohort study. Objectives: To investigate the usefulness of selective single-level lumbar endoscopic unilateral laminotomy for bilateral decompression (LE-ULBD) in patients with radiological multilevel lumbar spinal stenosis (LSS) and clarify the predictive factors of reoperation. Methods: A total of 128 patients who underwent LE-ULBD of radiological multilevel LSS were retrospectively examined. Single-level decompression was selected clinically and supplemented radiologically. Clinical outcomes were assessed with the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ), numeric rating scale (NRS), and Macnab criteria (mean follow-up period, 28.6 months [range, 24-63 months]). Stenosis severity was classified as grades M (moderate) and S (severe) based magnetic resonance imaging findings. Multilevel LSS was classified as SS, SM, and MM according to the number of grade S levels. Results: The follow-up rate was 74.2%. All domains of the JOABPEQ and NRS significantly improved during follow-up. The Macnab outcome classification was “excellent” or “good” in 77.9% of the patients. The reoperation rate was 10.2%. None of the patients with unilateral symptoms required reoperation. The SS type was a significant risk factor of reoperation for multilevel LSS with bilateral symptoms. Additional LE-ULBD was performed for all the reoperation with the “excellent” or “good” results of the Macnab criteria in 69% of the patients. Conclusions: Selective single-level LE-ULBD provided favorable results for multilevel LSS. However, information about the risks of reoperation for multilevel severe stenosis with bilateral symptoms should be shared between surgeons and patients.

Background/Purpose: Laminotomy is an established procedure to relieve symptoms of lumbar spinal stenosis. However, there is a group of patients with symptomatic recurrence. Re-decompression and fusion could be an effective salvage procedure but the results are seldom found in the literature. In this study, we focused on investigating the clinical outcomes and complication rates of revision decompression with fusion in this patient group. Methods: A retrospective study including patients who had undergone revision decompression with fusion for recurrent symptoms due to same level restenosis after primary laminotomy for lumbar spinal stenosis was performed. Patients with recurrent symptoms due to prolapsed intervertebral disc, trauma, infection, and neoplasm were excluded. Demographics, clinical outcomes, and complications were retrieved. Results: Twenty-eight patients with a total number of 42 levels of revision decompression and fusion were included. With a mean follow-up time of 27 months after revision surgery, there were statistically significant improvement of 63, 49, and 13% in Japanese Orthopaedic Association score, visual analog scale for leg pain, and Roland-Morris disability questionnaire score, respectively. There were 6(21%), 2(7%), 0(0%), and 2(7%) cases of dural tear, infection requiring reoperation, new neurological deficit, and other complications, respectively, in these revision cases. Conclusion: Bearing potential complications in mind, re-decompression with fusion is a viable option with reasonable clinical outcomes for patients with recurrent symptoms after laminotomy for lumbar spinal stenosis. As a treatment option for symptomatic lumbar spinal stenosis, primary laminotomy could have the potential benefit of lower complication rates in revision surgery.

Study Design: Prospective register cohort study. Objectives: The indication for surgery in patients with lumbar spinal stenosis (LSS) is considered to be leg pain and neurogenic claudication (NC). Nevertheless, a significant part of patients operated for LSS have mild leg pain levels defined as leg pain ≤minimally important clinical difference (MICD). Information is lacking on how to inform these patients about the probable outcome of surgery. The objective was to report the outcome of surgery for LSS in patients with a mild preoperative level of leg pain. Methods: A total of 2559 patients operated upon for LSS with preoperative leg pain ≤3 NRS (Numerical Rating Scale) were evaluated for outcome at the 1-year follow-up. NRS for back pain, the Oswestry Disability Index (ODI), and the EuroQol (EQ-5D) were used. Results: In the period 2007 to 2017, we identified 3239 patients (14%) who had mild leg pain (≤3 on the NRS). In this cohort, leg pain increased 0.40 (0.56-0.37) and back pain decreased 1.0 (0.95-1.2) at the 1-year follow up. ODI decreased 11.1 (10.2-11.4) and the EQ-5D increased 0.15 (0.17-0.14). A total of 31% reached successful outcome in terms of back pain, 43% in terms of ODI and 48% in terms of EQ-5D. 63% of the patients were satisfied with the outcome. Conclusion: A minority of patients with mild leg pain levels operated upon for LSS attain MICD for back pain, ODI, and EQ-5D. The results from this study can aid the surgeon in the shared decision-making process before surgery.

Background Lumbar spinal stenosis (LSS) and low-grade degenerative spondylolisthesis are frequently associated with facet joint degeneration, considered the main cause of low back pain. Surgery is the treatment of choice in patients affected by LSS unresponsive to conservative treatment. The aim of this study was to evaluate the clinical and radiologic outcome of patients treated with posterior decompression and transfacet fixation for single-level LSS and facet joint degeneration. Methods A total of 25 patients between May 2015 and June 2016 affected by radiologically demonstrated one-level LSS with facet joint degeneration and grade I spondylolisthesis were included in this prospective study. All the patients underwent laminectomy, foraminotomy, and one-level facet fixation (Facet-Link, Inc., Rockaway, New Jersey, United States). Pre- and postoperative clinical (Oswestry Disability Index [ODI], Short Form-36 [SF-36]) and radiologic (radiographs, magnetic resonance imaging, computed tomography) data were collected and analyzed. Results Mean follow-up was 12 months. The L4–L5 level was involved in 18 patients (72%) and L5–S1 in 7 patients (28%); the average operative time was 80 minutes (range: 65–148 minutes), and the mean blood loss was 160 mL (range: 90–200 mL). ODI and SF-36 showed a statistically significant (p < 0.05) improvement at last follow-up. Conclusions Transfacet fixation is a safe and effective treatment option in patients with single-level LSS, facet joint degeneration, and mild instability.

Degenerative lumbar spinal stenosis is a common condition and the most usual indication for spinal surgery in adult patients. The main objective of this study was to investigate clinical outcomes, health-related quality of life (HRQoL) and satisfaction among patients with a diagnosed lumbar spinal stenosis who were surgically treated, and whether these outcomes differed according to gender and age. Surgery was performed on 100 patients with clinical and radiological defined lumbar spinal stenosis. All patients completed questionnaires twice before surgery and at 6 weeks, 12 weeks, and 1 year postoperatively. Main outcomes were symptoms, physical function and patient satisfaction assessed by the Swiss Spinal Stenosis Questionnaire and HRQoL by the Short Form 36 health survey (SF36). There were large improvements in all clinical outcomes and in the physical subscales of the SF36. A marked reduction of average 32.3% was seen in symptoms already at 6 weeks follow-up. Physical function had improved with an average of 29.8% at 1-year follow-up. There was no statistical significant effect of age and gender on symptoms and physical function. Patients more than 65 years were significantly less satisfied at the 1-year follow-up as compared to the younger patients (p=0.012). This study showed that the majority of patients improved significantly in symptoms, physical function and physical HRQoL after surgery for degenerative lumbar spinal stenosis, regardless of age and gender. Age showed to be closely connected to satisfaction.

OBJECTIVELumbar spinal stenosis (LSS) is the most common spinal disease in the geriatric population, and is characterized by a compression of the lumbosacral neural roots from a narrowing of the lumbar spinal canal. LSS can result in symptomatic compression of the neural elements, requiring surgical treatment if conservative management fails. Different surgical techniques with or without fusion are currently treatment options. The purpose of this study was to provide a description of the long-term clinical outcomes of patients who underwent bilateral laminotomy compared with total laminectomy for LSS.METHODSThe authors retrospectively reviewed all the patients treated surgically by the senior author for LSS with total laminectomy and bilateral laminotomy with a minimum of 10 years of follow-up. Patients were divided into 2 treatment groups (total laminectomy, group 1; and bilateral laminotomy, group 2) according to the type of surgical decompression. Clinical outcomes measures included the visual analog scale (VAS), the 36-Item Short-Form Health Survey (SF-36) scores, and the Oswestry Disability Index (ODI). In addition, surgical parameters, reoperation rate, and complications were evaluated in both groups.RESULTSTwo hundred fourteen patients met the inclusion and exclusion criteria (105 and 109 patients in groups 1 and 2, respectively). The mean age at surgery was 69.5 years (range 58–77 years). Comparing pre- and postoperative values, both groups showed improvement in ODI and SF-36 scores; at final follow-up, a slightly better improvement was noted in the laminotomy group (mean ODI value 22.8, mean SF-36 value 70.2), considering the worse preoperative scores in this group (mean ODI value 70, mean SF-36 value 38.4) with respect to the laminectomy group (mean ODI 68.7 vs mean SF-36 value 36.3), but there were no statistically significant differences between the 2 groups. Significantly, in group 2 there was a lower incidence of reoperations (15.2% vs 3.7%, p = 0.0075).CONCLUSIONSBilateral laminotomy allows adequate and safe decompression of the spinal canal in patients with LSS; this technique ensures a significant improvement in patients’ symptoms, disability, and quality of life. Clinical outcomes are similar in both groups, but a lower incidence of complications and iatrogenic instability has been shown in the long term in the bilateral laminotomy group.

OBJECTIVE Several studies have examined the relationship between sagittal spinopelvic alignment and clinical outcomes after spinal surgery. However, the long-term reciprocal changes in sagittal spinopelvic alignment in patients with lumbar spinal stenosis after decompression surgery remain unclear. The aim of this study was to investigate radiographic changes in sagittal spinopelvic alignment and clinical outcomes at the 2-year and 5-year follow-ups after minimally invasive lumbar decompression surgery. METHODS The authors retrospectively studied the medical records of 110 patients who underwent bilateral decompression via a unilateral approach for lumbar spinal stenosis. Japanese Orthopaedic Association (JOA) and visual analog scale (VAS) scores for low-back pain (LBP), leg pain, leg numbness, and spinopelvic parameters were evaluated before surgery and at the 2-year and 5-year follow-ups. Sagittal malalignment was defined as a sagittal vertical axis (SVA) ≥ 50 mm. RESULTS Compared with baseline, lumbar lordosis significantly increased after decompression surgery at the 2-year (30.2° vs 38.5°, respectively; p < 0.001) and 5-year (30.2° vs 35.7°, respectively; p < 0.001) follow-ups. SVA significantly decreased at the 2-year follow-up compared with baseline (36.1 mm vs 51.5 mm, respectively; p < 0.001). However, there was no difference in SVA at the 5-year follow-up compared with baseline (50.6 mm vs 51.5 mm, respectively; p = 0.812). At the 5-year follow-up, 82.5% of patients with preoperative normal alignment maintained normal alignment, whereas 42.6% of patients with preoperative malalignment developed normal alignment. Preoperative sagittal malalignment was associated with the VAS score for LBP at baseline and 2-year and 5-year follow-ups and the JOA score at the 5-year follow-up. Postoperative sagittal malalignment was associated with the VAS score for LBP at the 2-year and 5-year follow-ups and the VAS score for leg pain at the 5-year follow-up. There was a trend toward deterioration in clinical outcomes in patients with persistent postural malalignment compared with other patients. CONCLUSIONS After minimally invasive surgery, spinal sagittal malalignment can convert to normal alignment at both short-term and long-term follow-ups. Sagittal malalignment has a negative impact on the VAS score for LBP and a weakly negative impact on the JOA score after decompression surgery.

Object. The authors applied the technique of microendoscopic discectomy to posterior decompression procedures for lumbar spinal stenosis. The purpose of this study was to determine the feasibility of using an endoscopic technique to treat lumbar spinal stenosis and to evaluate the clinical and radiographic results of microendoscopic posterior decompression (MEPD). Methods. Microendoscopic posterior decompression, which involves a unilateral endoscopic approach for bilateral decompression, was performed in 47 patients. Clinical and radiographic/neuroimaging results were evaluated during the follow-up period (minimum duration 1 year). The clinical results were compared with those of the conventional laminotomy. Radiographic instability and the degree of surgical invasion of the facet joints were evaluated. In a control a group of 29 patients open laminotomy was performed. The clinical outcome was evaluated in 44 patients. The mean follow-up duration was 22 months. The mean rate of improvement was 72% based on the Japanese Orthopaedic Association score, and good results were obtained in 38 patients. Although the rate of morbidity decreased in the MEPD group, the incidence of complication was slightly higher. Effective decompression was demonstrated in the majority of the patients by using magnetic resonance imaging. Radiographic instability appeared in one patient postoperatively, and based on computerized tomography scanning, a tendency toward invasion of the facet joint on the approach side was noted. Conclusions. Microendoscopic posterior decompression is a minimally invasive procedure and is as useful as other conventional procedures in treating lumbar spinal stenosis; however, a few technical problems remain to be solved.
