Abstract:
OBJECTIVE:To investigate the clinical efficacy of bilateral targeted puncture in percutaneous vertebroplasty(PVP) based on the vertebral osteodense zone.
METHODS:A retrospective analysis was conducted on 76 patients with fresh symptomatic osteoporotic vertebral compression fractures, characterized by the presence of a dense zone, who underwent percutaneous vertebroplasty (PVP) between January 2021 and December 2021. All patients involved single-level vertebral fractures. There were 19 males and 57 females, aged from 62 to 88 years old, with an average of (68.5±12.5) years old. All patients underwent bilateral transpedicular puncture procedures. Preoperative CT or MRI was utilized to ascertain the relative position of the bone osteodense zone within the vertebral body (specifically, whether this zone is situated in the upper one-third or one-quarter of the left or right sagittal plane). Considering the head and tail regions of the dense zone as puncture targets, the puncture points and paths were meticulously planned, and the working channel was subsequently established. Under continuous monitoring by a C-arm X-ray machine, bone cement was carefully and gradually injected. The operation time, bone cement injection volume, and bone cement leakage were recorded. The visual analogue scale (VAS) and Oswestry disablity index (ODI) were used to evaluate the effectiveness of the operation. ODI and anterior height (AH) of the vertebral body were used to evaluate the efficacy.
RESULTS:All patients successfully completed the surgery and were followed up for (8.0±1.0) months. The operation time was (36.57±11.25) min, the volume of bone cement injection was(6.07±1.19) ml, and 21 patients of bone cement leakage. There were 3 patients with the VAS exceeded 4 points two days postoperatively, indicating suboptimal pain management. At the three time points of pre-operation, 2 days post-operation and 6 months post-operation, the VAS scores were(7.82±1.29), (2.11±0.44), and (2.04±0.67) respectively;the ODI percentages were(75.65±7.23)%, (29.45±4.16)%, and(28.68±5.62)%;and the AH values were (11.02±1.30), (12.87±3.91), and (12.91±3.86) cm. The differences were all statistically significant(P<0.05). The aforementioned three indices demonstrated significant improvement at both 2 days and 6 months post-operation (all P<0.05). There were no statistically significant differences in these indices between the 2-day and 6-month post-operative periods(P>0.05). The postoperative outcome was satisfactory and durable, with no evidence of vertebral height reduction.
CONCLUSION:Bilateral targeted puncture based on the osteodense dense zone within the vertebral body can achieve bilateral symmetrical and upright full vertebral bone cement reinforcement without increasing bone cement leakage, achieving good early efficacy and preventing late vertebral collapse. This has positive significance for further improving the efficacy of percutaneous vertebroplasty.
