Abstract:
Objective:To explore the efficacy of percutaneous vertebroplasty (PVP) using the partition injection technique in the treatment of Kümmell’s disease of stages Ⅰ and Ⅱ.Methods:A retrospective study was conducted of the 30 patients with stage Ⅰ or Ⅱ Kümmell’s disease (the partition group) who had been treated by PVP using the partition injection technique at Department of Spinal Surgery, Zhengzhou Orthopedic Hospital from January 2020 to January 2022. The data of another 30 patients who had been treated at the same department and the same period using conventional PVP for stage Ⅰ or Ⅱ Kümmell's disease were selected as the conventional group. In the partition group, there were 13 males and 17 females, with an age of (72.3±10.1) years and disease duration of (3.1±1.5) months. Seventeen thoracic and 13 lumbar vertebrae were affected. In the conventional group, there were 11 males and 19 females, with an age of (75.5±12.7) years and disease duration of (3.5±1.8) months. Eighteen thoracic and 12 lumbar vertebrae were affected. Surgical time, volume of bone cement injected, bone cement leakage, and bone cement distribution were compared between the 2 groups. The heights of the anterior and middle vertebral bodies, kyphotic Cobb angle, visual analog scale (VAS) pain score, and Oswestry disability index (ODI) were assessed postoperatively at 1 day, 6 months, and the last follow-up and compared between the 2 groups.Results:No significant differences were found in the baseline data between the 2 groups, indicating comparability ( P>0.05). All patients were followed up for (17.3±3.1) months. There were no significant differences in the surgical time or bone cement leakage between the 2 groups ( P>0.05). The volume of bone cement injected in the partition group was significantly higher [(6.3±1.5) mL] than that in the conventional group [(4.9±1.0) mL] ( P<0.05). Bone cement distribution was significantly better in the partition group than that in the conventional group ( P<0.05). At postoperative 1 day, 6 months, and the last follow-up, the partition group was significantly better than the conventional group in anterior vertebral body height, middle vertebral body height, and kyphotic Cobb angle ( P<0.05). At the 6-month and the last follow-ups, the partition group was also significantly better than the conventional group in VAS pain score and ODI ( P<0.05). Conclusion:In the treatment of Kümmell’s disease of stages Ⅰ and Ⅱ, compared with conventional PVP, PVP using the partition injection technique may lead to better long-term outcomes due to its better bone cement distribution, more adequate cement injection, and better restoration of vertebral body heights and correction of local deformity.
