[The trend of changes in spine-pelvic sagittal parameters before and after surgery in patients with double-segment lumbar spondylolisthesis and their evaluating for surgery efficacy].

OBJECTIVE: To explore the trend of changes in the parameters of the spine-pelvic sagittal plane before and after surgery in patients with double-segment lumbar spondylolisthesis (LSL) and to evaluate the value of the surgical effect. METHODS: A retrospective analysis of 95 double-segment lumbar spondylolisthesis patients treated with posterior lumbar interbody fusion from October 2019 to October 2020 were analyzed, including 31 males and 64 females;age ranging from 41 to 63 years old, with an average of (52.10±4.35) years old;degree of lesion, 47 patients with gradeⅠand 48 patients with gradeⅡ. The surgical efficacy was evaluated according to the Oswestry dysfunction index(ODI) improvement rate at 3 months after operation. ODI improvement rate ≥50% was considered good, and <50% was considered bad. Ninety-five patients were divided into good curative effect group (74 cases) and poor curative effect group (21 cases) according to surgical curative effect. The clinical data, such as gender, age, body mass index, course of disease, degree of disease, operation time, intraoperative blood loss, and comorbidities were compared between two groups were compared. The parameters of spine pelvis sagittal plane were observed before and 3 months after operation, including spine sacral angle (SSA), T1 pelvic angle (TPA), lumbar lordosis (LL), pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS). Clinical symptoms were evaluated using visual analogue scale (VAS) and ODI. The correlation between the changes of spine pelvis sagittal plane parameters and the changes of VAS and ODI before and after surgery were analyzed, and the value of spine pelvis sagittal plane parameters in evaluating the surgical efficacy of patients with double level lumbar spondylolisthesis at 3 months after surgery was evaluated. RESULTS: The courses of disease and surgical time in the group with poor efficacy were longer than those in the group with good efficacy, and the degree of lesion was higher in the group with poor efficacy (P<0.05). The SSA, TPA, LL, and SS of the group with good efficacy were higher than those of the group with poor efficacy before and 3 months after surgery, while the PT was lower than that of the group with poor efficacy (P<0.05). The changes in SSA, TPA, LL, PT, and SS before and after surgery in the group with good efficacy were greater than those in the group with poor efficacy (P<0.05). The VAS and ODI of both groups were lower at 3 months after surgery than before, and the group with good efficacy was lower(P<0.05). The changes in VAS and ODI before and after surgery in the group with good efficacy were greater than those in the group with poor efficacy (P<0.05). The changes in SSA, TPA, LL, PT, SS before and after surgery were positively correlated with the changes in VAS and ODI (P<0.05). Three months after surgery, SSA, TPA, LL, PT, and SS were used to evaluate the surgical efficacy of patients with dual level lumbar spondylolisthesis. The area under the curve (AUC) was 0.868, 0.797, 0.875, 0.822, and 0.853, respectively. The combined evaluation of all indicators resulted in the highest AUC, 0.927, and the best sensitivity and specificity were 90.50% and 91.89%, respectively. CONCLUSION: The spine pelvis sagittal plane parameters SSA, TPA, LL, and SS of patients with double level lumbar spondylolisthesis before and after surgery show an upward trend;PT shows a downward trend;PI do not change significantly. And the changes of SSA, TPA, LL, SS, and PT are closely related to the patient's pain level and the improvement of lumbar function, which can be used as parameters to evaluate the surgical efficacy.

Analysis of the Nursing Effect of Anesthesia Care Integration Combined with Preventive Nursing on Older Patients with Lumbar Disc Herniation During the Perioperative Period.

Objective: This study explored the nursing effect of anesthesia care integration combined with preventive nursing on older patients with perioperative lumbar disc herniation (LDH). Methods: Clinical data of 100 older patients with LDH who were admitted to our hospital between May 2017 and May 2022 were used, and there were no patients who had not had surgery between January and May 2020 because of the COVID-19 pandemic. Based on the different nursing methods, the patients were divided into control and observation groups, with 50 cases each. The control group received anesthesia care integration, whereas the observation group received anesthesia care integration combined with preventive nursing. Lumbar spine function, pain score, anesthesia recovery assessment, and nursing effects were compared between the two groups. Results: The scores of the anesthesia recovery assessment of the two groups were compared, and the vital signs of the observation group during recovery from anesthesia were significantly better than those of the control group (P<0.05). After nursing care, the Japanese Orthopaedic Association (JOA) score of the observation group was significantly higher than that of the control group; however, the numerical scale (NRS) score of the observation group was significantly lower than that of the control group (P<0.05). After nursing care, the physical comfort, emotional state, psychological support, self-care ability, and pain scores were higher in the observation group than in the control group; however, the NRS score of the observation group was significantly lower than that of the control group (P<0.05). Conclusion: Anesthesia care integration combined with preventive nursing has a positive effect on older patients with perioperative LDH, and it significantly improves lumbar spine function, reduces pain, shortens recovery time, and benefits physical and mental health.

Effect of bone cement-reinforced pedicle screws combined with fusion repositioning therapy on lumbar spine function and postoperative complications in patients with severe lumbar spondylolisthesis.

Objective: To retrospectively study the efficacy of bone cement-enhanced pedicle screws combined with interbody fusion reduction in the treatment of severe lumbar spondylolisthesis, its effect on lumbar function and complications. Methods: From January 2019 to June 2021, 82 cases of severe lumbar spondylolisthesis in our hospital were analyzed. According to the different treatment plans, the patients were divided into two groups: A and B, in which group A patients were treated with pedicle screws combined with fusion and reduction, and group B patients were treated with bone cement reinforced pedicle screws combined with fusion and reduction. Perioperative indexes, pain severity (VAS), Oswestry dysfunction index (ODI), and low back and leg pain score of Japan Orthopedic Association (JOA), spondylolisthesis reduction, intervertebral space height, intervertebral foramen height, complications, and screw loosening were compared between the two groups. Results: There was no significant difference in the amount of intraoperative bleeding between group A and group B (P > 0.05). The operation time of group B was longer than that of group A, and the hospitalization time was shorter than that of group A. The vertebral fusion rate of group B was higher than that of group A (P < 0.05). The VAS, ODI and JOA scores at the last follow-up in both groups were lower than those before surgery, and group B was lower than group A (P < 0.05). Compared with the preoperative period, the postoperative slippage degree grading improved in both groups, while the improvement rate in group B was higher than that in group A (P < 0.05). At the last follow-up, the scores of intervertebral foramen height and intervertebral space height in both groups were higher than those before operation, and those in group B were higher than those in group A (P < 0.05). There was no difference in the incidence of complications and screw loosening between the two groups (P > 0.05). Conclusion: Compared with conventional screw treatment, bone cement-reinforced pedicle screws combined with fusion repositioning can further improve the repositioning rate of slipped vertebrae in the treatment of severe LSL, while achieving a better intervertebral fusion rate. Therefore, the treatment of severe LSL with bone cement reinforced pedicle fusion and reduction is a safe and effective method.

Curative Effect of Percutaneous Transforaminal Endoscopic Spine System in the Treatment of Lumbar Disc Herniation Complicated with Nerve Root Canal Stenosis / 中山大学学报(医学科学版)

ObjectiveTo explore the clinical efficacy of percutaneous transforaminal endoscopic spine system （TESSYS） in the treatment of lumbar disc herniation （LDH） complicated with nerve root canal stenosis. MethodsA retrospective study was done on 40 LDH patients complicated with nerve root canal stenosis who underwent TESSYS in our hospital from April 2019 to April 2021. The clinical efficacy of the patients was evaluated by the modified Mac Nab criteria 12 months after the surgery. We also measured and analyzed the scores of visual analogue scale （VAS）， Oswestry disability index （ODI） and Japanese orthopaedic association （JOA）， the changes of structural parameters of lumbar spine and inflammatory factor levels preoperatively， 6 and 12 months after the surgery. ResultsAll the 40 cases successfully underwent the surgery and follow-ups， with a 12-month post-operative clinical excellent and good rate of 90%. The preoperative， 6-month and 12-month post-operative VAS scores were （7.38±2.06）， （2.36±0.87） and （1.62±0.82）， respectively. The respective ODI scores were （55.54±11.19）， （26.52±7.61） and （18.14±4.36）； JOA scores （13.93±2.10）， （20.26±1.35） and （22.34±1.88）. The post-operative scores of VAS， ODI and JOA were significantly improved compared with those before the surgery （P<0.05）. The preoperative and post-operative lumbosacral angles were （37.23±6.84）° and （27.37±4.31）°， respectively， with the respective lumbar curvatures of （13.48±3.06） mm and （22.36±4.51） mm. The post-operative lumbosacral angle and lumbar curvature were significantly improved compared with those before the surgery （P<0.05）. The preoperative and post-operative high-sensitivity C-reactive protein （hs-CRP） levels were （3.43±0.61） mg/L and （5.18±0.70） mg/L， respectively， with the respective tumor necrosis factor alpha （TNF-α） levels of （1.44±0.27） mg/L and （2.07±0.44） mg/L. The post-operative levels of hs-CRP and TNF-α were significantly higher than those before the surgery （P<0.05）. ConclusionIn the treatment of LDH complicated with nerve root canal stenosis， TESSYS achieves a good clinical effect， improves the structure and function of the lumbar spine， reduces the degree of lumbar spine pain， and has a mild post-operative inflammatory reaction.
