AbstractThis study aimed to evaluate the efficacy and safety of bone cement-augmented pedicle screw fixation for stage III Kümmell disease. Twenty-five patients with stage III Kümmell disease who received bone cement-augmented pedicle screw fixation at the First Affiliated Hospital of Guangzhou University of Chinese Medicine between June 2009 and December 2015 were enrolled. All patients were females with a history of osteoporosis. The vertebral Cobb angle (V-Cobb angle), the fixed segment Cobb Angle (S-Cobb angle), pelvic parameters, visual Analogue Scale (VAS) score, and Oswestry Disability Index (ODI) were assessed preoperatively, postoperatively and at the final follow-up. Complications, loosening rate, operation time, and intraoperative bleeding were recorded. The average lumbar vertebral density T-value was − 3.68 ± 0.71 SD, and the average age was 71.84 ± 5.39. The V-Cobb angle, S-Cobb angle, and Sagittal Vertical Axis (SVA) were significantly smaller postoperatively compared to the preoperative values. The VAS and ODI at 1 month after surgery were 3.60 ± 1.00 and 36.04 ± 6.12%, respectively, which were both significantly lower than before surgery (VAS: 8.56 ± 1.04, ODI: 77.80 ± 6.57%). Bone cement-augmented pedicle screw fixation is a safe and effective treatment for stage III Kümmell disease. It can effectively correct kyphosis, restore and maintain sagittal balance, and maintain spinal stability.

Abstract Background Lumbar interbody fusion is a recognized surgical technique in treatment of degenerative lumbar instability. Interbody fusion supplemented with pedicle screw fixation has several advantages over posterolateral fusion and has been advocated to improve fusion rates and clinical outcomes. Interbody fusion places the bone graft in the loadbearing position of the anterior and middle spinal columns thereby enhancing the potential for fusion. In addition, the interbody space has more vascularity than the posterolateral space, also increasing the potential for a solid fusion mass to form. Aim of the Work to assess safety and efficacy of unilateral pedicle screw fixation associated with interbody fusion in Lumbar spine degenerative diseases and to evaluate and compare outcomes of unilateral versus bilateral pedicle screw fixation associated with interbody fusion in lumbar spine degenerative diseases, as regard the operation time, bleeding, postoperative stay, cost, and the clinical and biomechanical results. Material & Methods This observational prospective comparative study of the 2 groups who were operated either unilateral (Group A /25 patients) or bilateral (Group B/25 patients) pedicle screw fixation with interbody fusion was done. Patients were followed up for 1, 6, 12 months. This study occurred at Ain Shams University hospitals. Results No differences were observed between the two groups with respect to demographic data. The patients of the two groups had significant improvement in functional outcome compared to preoperatively, except in early postoperative VAS back and ODI in unilateral group which is better than bilateral group. However, no significant difference noticed in the further follow up. There was no significant difference comparing fusion rate, complication rate and duration of hospital stay between the two groups at postoperative follow-up. There was significantly less blood loss, shorter postoperative pain killer use and significantly shorter operation time in the unilateral PS fixation group as compared with the bilateral PS fixation group in our study. Conclusion Our study suggested TLIF with unilateral PS fixation was as safe and effective as that with bilateral PS fixation. Unilateral PS fixation may significantly reduce the intraoperative blood loss and shorten the operation time, somewhat improve the clinical outcome scores of ODI and VAS Back without significant difference comparing fusion rate, complication rate and duration of hospital stay between the two groups at postoperative follow-up. BPSF with TLIF likely causes more degeneration at the cranial adjacent segment compared with UPSF techniques. However, the long-term follow up is required to demonstrate the impact of these findings.

Abstract Background: Percutaneous mesh-container-plasty (PMCP) and pedicle screw fixation plus vertebroplasty (PSFV) were developed with advantages of bone cement leakage, height restoration and kyphotic angle reduction in osteoporotic vertebral compression fractures (OVBF). The purpose of the current study was to compare the effects and safety between PMCP and PSFV for treatment of thoracolumbar OVBF. Methods: A retrospective study of 227 consecutive patients with thoracolumbar OVBF without neurologic deficit who underwent PMCP (n=109) or PSFV (n=118) was conducted. The epidemiological data, surgical outcomes, clinical and radiological features were compared between the 2 groups. Clinical evaluation of VAS and ODI, and radiological evaluation of height restoration, deformity correction, cement leakages and canal compromise were calculated on preoperative, postoperative and 2 years postoperative.Results: Cost(4.82±0.21 vs. 5.50±0.29, P<0.05), blood loss(7.36±3.67 vs. 22.52±4.79, P<0.05), operation time(34.35±8.72 vs. 92.70±17.24, P<0.05) and hospital day(4.42±1.62 vs. 5.46±2.31, P<0.05) were significantly lower in the PMCP group than in the PSFV group. VAS [2(1,3) vs. 3(2.75,4), P<0.05] and ODI (21.01±7.90 vs. 33.81±8.81, P<0.05) scores were significantly lower in the PMCP group than in the PSFV group postoperative. However, no statistical difference was found in VAS and ODI between group PMCP and PSFV 2 years postoperative. Anterior(85.63±8.22% vs. 74.86±12.60%; 83.49±8.95% vs. 68.77±11.32%; P<0.05) and middle vertebral body height ratio(84.68±7.69% vs. 71.05±12.68%; 82.47±8.34% vs. 74.96±12.90%; P<0.05) were significantly higher in the PSFV group than in the PMCP group postoperative. Cobb angle(7.95±4.42 vs. 11.99±5.69, 8.59±4.46 vs. 12.95±5.74; P<0.05) and canal compromise(19.85±6.18 vs. 10.18±6.99, 10.03±7.20 vs. 19.90±5.98; P<0.05) were significantly lower in group PSFV than in the PMCP group postoperative. No statistical difference was found in cement leakage between group PMCP and PSFV. Conclusion: Despite of relative worse radiological results, PMCP is a safe, minimally invasive, and cost-effective surgical method and can obtain better satisfactory clinical results compared to PSFV for OVBF.

Abstract PurposeThis study aims to investigate the necessity of cement-augmented pedicle screw fixation in single-segment isthmic spondylolisthesis with osteoporosis.MethodFifty-nine cases were reviewed retrospectively. Thirty-three cases were in the polymethylmethacrylate-augmented pedicle screw (PMMA-PS) group, and the other 26 cases were in the conventional pedicle screw (CPS) group. Evaluation data included operation time, intraoperative blood loss,hospitalization cost, hospitalization days, rates of fusion, screw loosening, bone cement leakage, visual analog scores (VAS) , Oswestry disability index (ODI) , Lumbar Lordosis（LL）, Pelvic Tilt（PT） and Sacral Slope（SS）. ResultsThe operation time and blood loss in the CPS group decreased significantly compared to the PMMA-PS group (P < 0.05). The average hospitalization cost of the PMMA group was significantly higher than that of the CPS group (P < 0.05). There was no significant difference for the average hospital stay between the 2 groups (P > 0.05). The initial and the last follow-up postoperative VAS and ODI improved significantly in the two groups (P < 0.05). There were no significant differences in VAS and ODI at each time point between the 2 groups (P > 0.05). The last postoperative spine-pelvic parameters were significantly improved compared with preoperation (P < 0.05). In the PMMA-PS group, the fusion rate was 100%. The fusion rate was 96.15% in the CPS group. No significant difference was found between the two groups for the fusion rate (P > 0.05). Nine cases in the PMMA-PS group had bone cement leakage (27.27%). There was not screw loosening in the PMMA-PS group. There were 2 cases of screw loosening in the CPS group. There were no significant differences in screw loosening, postoperative adjacent segment fractures, postoperative infection or postoperative revision between the 2 groups (P > 0.05). ConclusionsThe use of PMMA-PS on a regular basis is not recommended for posterior lumbar interbody fusion for the treatment of single-segment isthmic spondylolisthesis with osteoporosis.
