Abstract: [Objective] To compare the clinical outcomes of percutaneous vertebroplasty (PVP) versus cement-augmented pedicle screw combined with PVP (PSPVP) for stage III Kummell s disease without neurological symptoms. [Methods] From June 2015 to September 2018, a total of 60 patients who suffered from stage III Kummell??s disease without neurological symptoms were included into this study in our hospital. Of them, 30 patients had PVP, while the remaining 30 patients underwent PSPVP. The perioperative, follow- up and radiographic documentations were compared between the two groups. [Results] All the 60 patients had surgical procedures performed smoothly without serious complications. The PVP group proved significantly superior to the PSPVP group regarding operation time, volume of cement injected, frequency of intraoperative fluoroscopy, intraoperative blood loss and hospital stay postoperatively (P<0.05) . The follow-up period lasted for more than 12 months. The VAS and ODI scores significantly decreased postoperatively with contrast to those before operation in both groups (P<0.05) , nevertheless no statistically significant differences in these scores were found between the two groups at any matching time point (P> 0.05) . In term of radiographic assessment, cement leakage revealed by radiographs was of 5 cases (16.67%) in the PVP group,whereas 4 cases (13.34%) in the PSPVP group, with on corresponding neurological defect in anyone of the cement leakage. The relative anterior vertebral height significantly increased, whereas local kyphotic Cobb ??s angle of affected vertebra significantly decreased at 1 day and the latest follow up compared with those before operation in both groups (P<0.05) . Regardless no statistically significant differences between the two groups before operation (P>0.05) , the PSPVP group proved significantly superior to the PVP group in the relative anterior vertebral height and local kyphotic Cobb??s angle of affected vertebra at the latest follow up (P<0.05) . [Conclusion] Both PVP and PSPVP are safe and effective for treatment of stage III Kummell's disease without neurological symptoms. By comparison, PVP has advantages of shorter operation time, less blood loss and fewer postoperative hospital stay, while the PSPVP has benefit of better deformity correction.
