Abstract Background Percutaneous kyphoplasty (PKP), percutaneous mesh-container-plasty (PMCP) and pedicle screw fixation plus vertebroplasty (PSFV) were three methods for osteoporotic vertebral burst fractures (OVBF). The purpose of the current study was to evaluate the clinical safety and efficacy of PKP, PMCP, and PSFV for OVBFs. Methods This retrospective study included 338 consecutive patients with thoracolumbar OVBFs who underwent PKP (n = 111), PMCP (n = 109), or PSFV (n = 118) and compared their epidemiological data, surgical outcomes, and clinical and radiological features. Clinical evaluations of VAS and ODI and radiological evaluations of height restoration, deformity correction, cement leakage, and canal compromise were calculated preoperatively, postoperatively, and 2 years postoperatively. Results Cement leakage (31/111 vs. 13/109 and 16/118, P < 0.05) was significantly higher in group PKP than in groups PSFV and PMCP. VAS and ODI scores improved postoperatively from 7.04 ± 1.15 and 67.11 ± 13.49 to 2.27 ± 1.04 and 22.00 ± 11.20, respectively, in group PKP (P < 0.05); from 7.04 ± 1.29 and 67.26 ± 12.79 to 2.17 ± 0.98 and 21.01 ± 7.90, respectively, in group PMCP (P < 0.05); and from 7.10 ± 1.37 and 67.36 ± 13.11 to 3.19 ± 1.06 and 33.81 ± 8.81, respectively, in the PSFV group (P < 0.05). Moreover, postoperative VAS and ODI scores were significantly higher in group PSFV than in groups PKP and PMCP (P < 0.05). However, VAS scores were not significantly different in the three groups 2 years postoperatively (P > 0.05). Postoperative anterior (81.04 ± 10.18% and 87.51 ± 8.94% vs. 93.46 ± 6.42%, P < 0.05) and middle vertebral body height ratio (83.01 ± 10.16% and 87.79 ± 11.62% vs. 92.38 ± 6.00%, P < 0.05) were significantly higher in group PSFV than in groups PMCP and PKP. Postoperatively, Cobb angle (10.04 ± 4.26° and 8.16 ± 5.76° vs. 4.97 ± 4.60°, P < 0.05) and canal compromise (20.76 ± 6.32 and 19.85 ± 6.18 vs. 10.18 ± 6.99, P < 0.05) were significantly lower in group PSFV than in groups PMCP and PKP. Conclusion Despite relatively worse radiological results, PMCP is a safe and minimally invasive surgical method that can obtain better short-term clinical results than PKP and PSFV for OVBFs.

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.
