Abstract Background This paper is to first describe percutaneous endoscopy in the treatment of lumbar spinal stenosis secondary to ligamentum flavum hypertrophy targetedly. To investigate the efficacy and safety of percutaneous endoscopy in the treatment of this kind of lumbar spinal stenosis in elderly patients. Method: A retrospective analysis of 40 elderly patients with lumbar spinal stenosis secondary to ligamentum flavum hypertrophy admitted between January 2016 and January 2018 was performed. According to different surgical methods, they were divided into two groups: the control group and the endoscopy group (interlaminar approach), 20 people per group. There were 9 males and 11 females in the control group; the age of patients was 65.65 ± 4.44years, and the average disease duration was 4.55 ± 1.85 years. Besides, There were 10 males and 10 females in the endoscopy group; the age of patients was 67.30 ± 4.23years, and the average disease duration was 4.95 ± 2.04 years. Collect and count surgical-related indicators, preoperative and postoperative radiologic findings, incision visual analogue scale (VAS), lumbar and leg pain VAS, lumbar Japanese Orthopaedic Association (JOA) and Oswestry disability index (ODI) scores of all patients. Result A series of surgical indicators (including the operation time, the quantity of bleeding and postoperative hospital stay) in the endoscopy group was significantly lower than that in the control group (p < 0.05). The incision VAS score in the endoscopy group was also significantly lower than that in the control group at each time after surgery (p < 0.05). Besides, compared with the control group, in the endoscopy group, the leg pain VAS score and lumbar ODI score after surgery were significantly decreased (p < 0.05). Compared with the control group, in the endoscopy group, the lumbar JOA score was significantly higher (p < 0.05). Conclusion Percutaneous endoscopic technique is a small trauma, quick recovery, safe and effective minimally invasive surgery for patients with lumbar spinal stenosis secondary to ligamentum flavum hypertrophy.

Study Design: Retrospective study. Objective: To compare the clinical efficacy of posterior lumbar laminectomy decompression under full endoscopic technique (Endo-LOVE) and percutaneous endoscopic medial foraminal decompression (PE-MFD) in the treatment of degenerative lumbar spinal stenosis (DLSS). Methods: Between April 2017 and April 2018, 96 patients with DLSS underwent Endo-LOVE or PE-MFD, including 58 with Endo-LOVE and 38 with PE-MFD. After propensity score matching (PSM), patient characteristics, operation time, intraoperative fluoroscopy times, postoperative bedridden time, hospital stay and postoperative complications were recorded and compared. The clinical efficacy was evaluated according to Oswestry disability index (ODI), visual analogue scale (VAS), lumbar disease JOA and modified MacNab criteria. Results: A total of 96 patients with DLSS were included in the study. After PSM, the 2 groups were comparable in patient demographic and baseline characteristics. The operation time and intraoperative fluoroscopy times in PE-MFD group were significantly more than those in Endo-LOVE group ( P < .05). The operation time in PE-MFD group was significantly less than that in Endo-LOVE group ( P < .05). The intraoperative fluoroscopy times in PE-MFD group were significantly more than that in Endo-LOVE group ( P < .05). The ODI, VAS and lumbar disease JOA in the 2 groups were significantly improved comparing with those before operation ( P < .05). According to the modified MacNab criteria, the excellent and good rates of the 2 groups were 93.5% in Endo-LOVE group and 87.1% in PE-MFD group ( P > .05). Conclusion: Endo-LOVE and PE-MFD technique can both effectively treat DLSS, and the short-term follow-up results are positive. Endo-LOVE technique has the advantages of fast puncture positioning, less radiation exposure and wider indications. However, PE-MFD needs more radiation exposure and has the possibility of incomplete decompression for complex multiplanar spinal stenosis.

Abstract Background: To analyze the relational factors influencing the formation of cauda equina redundant nerve roots (RNRs) of the lumbar spinal stenosis.Methods: A retrospective study of 116 patients with lumbar spinal stenosis were treated in our department from January 2016 to June 2019. Magnetic resonance imaging (MRI) was performed to observe the shape and morphology of the redundant nerve roots of the cauda equina.We divided patient into (RNRs) group and non-RNRs( NRNRs) group based on the presence or absence of RNRs on sagittal T2-weighted MR. We analyzed the demographic characteristics, preoperative back pain visual analogue scale (VAS) scores ,preoperative leg pain VAS scores, and preoperative Oswestry disability index(ODI) scores, and also analyzed the rate of spondylolisthesis and ligamentum flavum hypertrophy. Simultaneously,the inter-vertebral height, intervertebral foramen height, inter-vertebral height +vertebral height, median sagittal diameter at the inter-vertebral space level(DIW-MSD),median sagittal diameter at the pedicel level(DV-MSD),ROM of the stenotic segment, were statistically analyzed for clinical and radiological significance.Results : Of a total 116 total patients,there were no statistically significant differences in either gender [RNRs group (n = 42, 18/24 female) and NRNR group (n = 74, 38/36 female)], age, BMI index, preoperative back pain VAS score , preoperative leg pain VAS score and preoperative ODI score(p> 0.05);however, there were statistically significant differences regard to the duration of symptoms and the rate of spondylolisthesis and ligamentum flavum hypertrophy (p<0.05);the inter-vertebral height,Intervertebral foramen height, inter-vertebral height+vertebral height, DIW-MSD ,ROM of the stenotic segment were also significantly different between the group (p<0.05).Conclusions:The inter-vertebral height, inter-vertebral foramen height, inter-vertebral height + vertebral height, DIW-MSD and ROM of the stenotic segment were the crucial factors related to RNRs in lumbar spinal stenosis.

<sec><title>Study Design</title><p>Histopathological analyses were performed in ligamentum flavum (LF) hypertrophy patients with lumbar spinal stenosis (LSS) and lumbar disc herniation (LDH).</p></sec><sec><title>Purpose</title><p>The aim of the present study was to evaluate histopathological changes in LF patients with LSS and LDH.</p></sec><sec><title>Overview of Literature</title><p>LSS is the most common spinal disorder in elderly patients. This condition causes lower back and leg pain and paresis, and occurs as a result of degenerative changes in the lumbar spine, including bulging of the intervertebral discs, bony proliferation of the facet joints, and LF thickening; among these, LF thickening is considered a major contributor to the development of LSS.</p></sec><sec><title>Methods</title><p>A total of 71 patients operated with the surgical indications of LSS and LDH were included. LF samples were obtained from 31 patients who underwent decompressive laminectomy for symptomatic degenerative LSS (stenotic group) and from 40 patients who underwent lumbar discectomy for LDH (discectomy group). LF materials were examined histopathologically, and other specimens were examined for collagen content, elastic fiber number and array, and presence of calcification.</p></sec><sec><title>Results</title><p>The stenotic and discectomy groups did not differ with regard to mean collagen concentration or mean elastic fiber number (p=0.430 and p=0.457, respectively). Mean elastic fiber alignment was 2.36±0.99 in the stenotic group and 1.38±0.54 in the discectomy group (<italic>p</italic>&lt;0.001). Mean calcification was 0.39±0.50 in the stenotic group, whereas calcification was not detected (0.00±0.00) in the discectomy group; a statistically significant difference was detected (<italic>p</italic>&lt;0.001) between groups.</p></sec><sec><title>Conclusions</title><p>LF hypertrophy in spinal stenosis may occur as a result of elastic fiber misalignment along with the development of calcification over time. Further studies determining the pathogenesis of LSS are needed.</p></sec>
