Abstract Background Spinal stenosis is frequently caused by spondylolisthesis, and surgical treatment may be indicated. However, whether decompression alone or decompression with dynamic stabilization offers better surgical outcomes remains unclear. We compared the clinical and radiologic results of patients with single-level lumbar spinal stenosis and grade 1 spondylolisthesis undergoing microsurgical decompression alone or decompression with transpedicular dorsal dynamic stabilization. Methods We retrospectively analyzed 20 patients undergoing microsurgical decompression and dorsal dynamic transpedicular stabilization using polyetheretherketone (PEEK) rods in one center from 2011 to 2017. Twenty patients with the same diagnosis undergoing microsurgical decompression alone were used as controls. Reoperation of the index and neighboring segments, back/leg pain, neurologic deficits, and the use of pain medication were assessed. For stabilization patients, radiographic progression of degeneration in the neighboring segments, listhesis degree in the index segment, and implant failure were assessed. Results All patients had good clinical outcomes at 3 and 12 months postoperatively. In stabilization patients, the visual analog scale (VAS) score for leg pain decreased from 5 points (median) to 1.6 at 3 months and 0.6 at 1 year postoperatively. In controls, the VAS score improved from 4.8 points to 1.1 at 3 months and 0.3 at 1 year postoperatively. The VAS score for back pain in stabilization patients decreased from 7.6 points (median) to 1.7 at 3 months and 0.1 at 1 year postoperatively. In controls, it decreased from 7.7 points to 1.1 at 3 months and 0.2 at 1 year postoperatively. In patients with additional dynamic stabilization, a longer hospital stay (stabilization group: 8.7 ± 4.1; control: 6.2 ± 1.6 days), longer operative time (stabilization group: 132.7 ± 41.3; control: 83.2 ± 31.7 minutes), and higher complication rates (revision surgery performed in two stabilization patients) were found. Conclusion No indications in our study showed that additional dynamic stabilization with PEEK rods offers any advantage over decompression alone.

Introduction: Spinal stenosis mostly occur in lumbar spine and causes back pain, leg pain & neurogenic claudication. Although conservative treatment is mainstay, decompression with or without fusion (with or without instrumentation) can be considered in non-responsive cases. However, long term outcome of the surgery is controversial. The aim of our study was to analyze the outcome of surgery in lumbar spinal stenosis in terms of post-operative pain and claudication distance.Methods: A prospective analysis of patients who underwent decompression or decompression with fusion (with or without instrumentation), after failure of 3-6 months conservative treatment, for lumbar spinal stenosis were conducted. Only those who were operated and followed up for at least two years were included.Their preop and postop VAS score and walking distance compared.Results: Of 22 cases enrolled in this study, VAS score was improved in 21 patients and walking distance increased. Only one patient complained of increase in pain score at 24 months.Conclusion: Operative management is a good option for selected patients, 21 out of 22 have improved VAS and claudication distance in our study

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.

OBJECTIVEThe authors evaluated the long-term clinical outcome of a total posterior arthroplasty system in the surgical treatment of lumbar spinal stenosis with degenerative spondylolisthesis.METHODSBetween June 2006 and July 2007, 10 patients with neurogenic claudication due to spinal stenosis and single-level degenerative spondylolisthesis were enrolled in a nonrandomized prospective clinical study. The patients were evaluated with radiographs and MRI scans, the visual analog scale (VAS) for back and leg pain, the Oswestry Disability Index (ODI), and the SF-36 health survey preoperatively and at 6 weeks, 3 months, 6 months, 1 year, 2 years, 3 years, 7 years, and 11 years postoperatively.RESULTSThe mean VAS score for leg pain dropped from 83.5 before surgery to 13 at 6 weeks and 17 at 11 years after surgery. The mean VAS score for back pain dropped from 56.2 preoperatively to 12.5 at 6 weeks and 14 at 11 years after surgery. The mean ODI score decreased from 49.1 preoperatively to 13.5 at 6 weeks and 16 at 11 years after surgery. MRI at 11 years demonstrated stenosis adjacent to the stabilized segment in one patient. This patient was not symptomatic. The authors did not find evidence of progression of the spondylolisthesis in any of the cases. In one patient, conversion to posterolateral fusion was performed due to an early device malfunction.CONCLUSIONSThe results of this 11-year follow-up study demonstrate that, in patients with spinal stenosis and degenerative spondylolisthesis, decompression and posterior arthroplasty maintain clinical improvement and radiological stability.

Objective.Selective, bilateral multisegmental microsurgical decompression of lumbar spinal canal stenosis through separate, alternating cross-over approaches.Indications. Two-segmental and multisegmental degenerative central and lateral lumbar spinal stenosis.Contraindications. None.Surgical Technique.Minimally invasive, muscle, and facet joint-sparing bilateral decompression of the lumbar spinal canal through 2 or more alternating microsurgical cross-over approaches from one side.Results.From December 2010 until December 2015 we operated on 202 patients with 2 or multisegmental stenosis (115 f; 87 m; average age 69.3 yrs, range 51–91 yrs). All patients were suffering from symptoms typical of a degenerative lumbar spinal stenosis. All patients complained about back pain; however the leg symptoms were dominant in all cases. Per decompressed segment, the average OR time was 36 min and the blood loss 45.7 cc. Patients were mobilized 6 hrs postop and hospitalization averaged 5.9 days. A total of 116/202 patients did not need submuscular drainage. 27/202 patients suffered from a complication (13.4%). Dural tears occurred in 3.5%, an epidural hematoma in 5.5%, a deep wound infection in 1.98%, and a temporary radiculopathy postop in 1.5%. Postop follow-up ranged from 12 to 24 months. There was a significant improvement of EQ 5 D, Oswestry Disability Index (ODI), VAS for Back and Leg Pain, and preoperative standing times and walking distances.

OBJECTIVEThe predominant symptom of lumbar spinal stenosis (LSS) is neurogenic claudication or radicular pain. Some surgeons believe that the presence of substantial back pain is an indication for fusion, and that decompression alone may lead to worsening of back pain from destabilization associated with facet resection. The purpose of this study was to determine if patients with LSS and clinically significant back pain could obtain substantial improvements in back pain after a decompression alone without fusion.METHODSThe DaneSpine database was used to identify 2737 patients with LSS without segmental instability and a baseline back pain visual analog scale (VAS) score ≥ 50 who underwent a decompression procedure alone without fusion. Standard demographic and surgical variables and patient outcomes, including back and leg pain VAS score (0–100), Oswestry Disability Index (ODI), and EQ-5D at baseline and at 12 months postoperatively, were collected.RESULTSA total of 1891 patients (69%) had 12-month follow-up data available for analysis; the mean age was 66.4 years, 860 (46%) were male, the mean BMI was 27.8 kg/m2, and 508 (27%) were current smokers. At 12 months postoperatively, there were statistically significant improvements (p < 0.001) from baseline for back pain (72.1 to 42.1), leg pain (71.2 to 41.3), EQ-5D (0.35 to 0.61), and ODI (44.1 to 27.8).CONCLUSIONSPatients with LSS, clinically substantial back pain, and no structural instability obtain improvement in back pain after decompression-only surgery and do not need a concomitant fusion.

The Impact

Study Design: Retrospective cohort study. Objectives: To analyze the impact of performing a formal decompression in patients with adult lumbar scoliosis with symptomatic spinal stenosis on perioperative complications and long-term outcomes. Methods: Adult patients undergoing at least 5 levels of fusion to the sacrum with iliac fixation from 2002 to 2008 who had a minimum 5-year follow-up at one institution were studied. Patients who had 3-column osteotomy were excluded from the study. Perioperative complications and clinical outcomes (Scoliosis Research Society [SRS], Oswestry Disability Index [ODI], and Numerical Rating Scale [NRS] back/leg pain) were analyzed. Patients who underwent formal laminectomy/decompressions were compared with those who did not. Differences between the 2 groups were analyzed using Student’s t test. Results: A total of 147 patients were included in the study (Decompression: n = 55 [37%], No decompression: n = 92 [63%]). Average fusion levels for the decompression and no decompression groups were 11 and 12 levels, respectively ( P = .26). Mean improvements in SRS domains for decompression versus no decompression patients, respectively, were pain (1.1 vs 0.9, P = .3), function (0.7 vs 0.5, P = .09), self-image (1.1 vs 1.1, P = .9), and mental health (0.5 vs 0.4, P = .5). Furthermore, additional mean improvements were ODI (21 vs 21, P = .14), NRS-Back pain (3.0 vs 1.3, P = .16), and NRS-Leg pain (3.9 vs 0.5, P = .002). Complication rates between the decompression group and no decompression group differed in incidental durotomies (18.2% vs 0%) and cardiac-related (9.1% vs 1.1%). Conclusions: Performing a formal decompression in adult lumbar scoliosis with symptomatic spinal stenosis is associated with increased perioperative complications but favorable long-term clinical outcomes.

Object. The authors investigated the causes of unsatisfactory outcomes in patients who had undergone instrumentation-assisted lumbar surgery and followed the clinical and imaging results of the revision surgery. Methods. Myelography and postmyelography computed tomography (CT) scanning were successfully conducted in 103 patients. In nearly 80% of these patients, the main symptom was back pain, with or without leg pain. Additional electromyography and nerve conduction velocity studies were also conducted in 22 patients in whom CT myelography could not help to establish the definitive cause of surgical failure. There were 26 cases of spinal stenosis, 13 of adjacent-segment instability, 15 of pseudarthrosis, 11 of screw misplacement, four of epidural fibrosis, five of arachnoiditis, seven of disc disruption, and 22 miscellaneous. When conservative treatment failed to relieve symptoms, surgery was suggested whenever an operable lesion was found. Revision surgery was performed in 48 patients, and these cases form the basis of this retrospective cohort study. All patients underwent clinical and imaging follow up for a minimum of 2 years. Two-year clinical outcomes were assessed using the 36-Item Short Form Health Survey questionnaire and compared with earlier scores using the Student t-test. Fusion status was evaluated by two orthopedic surgeons, who examined flexion–extension x-ray films or CT studies. The greatest improvement after revision surgery was documented in patients with symptoms related to spinal stenosis or disc disruption. Little improvement was observed in patients with misplaced pedicle screws causing nerve injury and those with epidural fibrosis or arachnoiditis. Conclusions. Adequate decompression at the initial operation and prevention of restenosis or accelerated adjacent-segment degeneration yielded the most favorable prognosis in the present cases. Successful posterolateral arthrodesis combined with supplemental interbody fusion improved the surgical outcomes in cases involving disc disruption or degeneration.

OBJECTIVEHigh-quality studies that compare outcomes of open and minimally invasively placed pedicle screws for adult spinal deformity are needed. Therefore, the authors compared differences in complications from a circumferential minimally invasive spine (MIS) surgery and those from a hybrid surgery.METHODSA retrospective review of a multicenter database of patients with spinal deformity who were treated with an MIS surgery was performed. Database inclusion criteria included an age of ≥ 18 years and at least 1 of the following: a coronal Cobb angle of > 20°, a sagittal vertical axis of > 5 cm, a pelvic incidence–lumbar lordosis angle of > 10°, and/or a pelvic tilt of > 20°. Patients were propensity matched according to the levels instrumented.RESULTSIn this database, a complete data set was available for 165 patients, and after those who underwent 3-column osteotomy were excluded, 137 patients were available for analysis; 76 patients remained after propensity matching (MIS surgery group 38 patients, hybrid surgery group 38 patients). The authors found no difference in demographics, number of levels instrumented, or preoperative and postoperative radiographic results. At least 1 complication was suffered by 55.3% of patients in the hybrid surgery group and 44.7% of those in the MIS surgery group (p = 0.359). Patients in the MIS surgery group had significantly fewer neurological, operative, and minor complications than those in the hybrid surgery group. The reoperation rates in both groups were similar. The most common complication category for the MIS surgery group was radiographic and for the hybrid surgery group was neurological. Patients in both groups experienced postoperative improvement in their Oswestry Disability Index and visual analog scale (VAS) back and leg pain scores (all p < 0.05); however, MIS surgery provided a greater reduction in leg pain according to VAS scores.CONCLUSIONSOverall complication rates in the MIS and hybrid surgery groups were similar. MIS surgery resulted in significantly fewer neurological, operative, and minor complications. Reoperation rates in the 2 groups were similar, and despite complications, the patients reported significant improvement in their pain and function.

Purpose: a comparative analysis of long-term clinical and radiological outcomes of bilateral microsurgical decompression from unilateral approach and open fusion surgery in the treatment of patients with stable stage I lumbar degenerative spondylolisthesis complicated by spinal stenosis. Materials and methods: this study included 83 patients with degenerative stage I lumbar spondylolisthesis, combined with spinal stenosis at one/several levels. Bilateral microsurgical decompression from unilateral approach was performed in group A (n = 41), in group B (n = 42) we used transforaminal lumbar interbody fusion. Results: intraoperative blood loss and operation time significantly prevailed in group B (P < 0,05). Pain in the legs (VAS), Oswestry disability index significantly decreased in both groups in the long-term postoperative period. No statistical difference in these was found in groups A and B (P = 0,59; P = 0,10). Lower back pain in both groups at the follow-up period had a significant difference: in fusion group there was a significantly higher intensity, than in group А (P < 0,001). Assessment of radiological outcomes in group A at the level of spondylolisthesis showed a slight decrease in segment stability: an increase in anteroposterior displacement of the vertebrae by an average of 0,44 mm, the angular difference by 0,77°, an increase in displacement of the vertebral body by 1,30 % (P < 0,05). Conclusion: minimally bilateral microsurgical decompression from unilateral approach is an effective method for treatment of stable stage I degenerative lumbar spondylolisthesis, combined with spinal stenosis, allowing to achieve significant regression of leg pain and disability in the long-term postoperative period. And this method admits to significantly decrease of low back pain, then in fusion surgery, as well as a low risk of postoperative instability and reoperation with instrumentation.
