Percutaneous vertebroplasty (PVP) is an effective method for the treatment of neurologically intact Kümmell’s disease, but bone cement leakage during surgery is a problem that deserves attention.
To reduce bone cement leakage and evaluate the effect of the sequential infusion of bone cement during PVP for the treatment of stage I or II Kümmell’s disease.
To compare the clinical effect of sequential bone cement infusion and traditional bone cement infusion in the treatment of stage I or II Kümmell’s disease.
Patients with Kümmell’s disease treated in our hospital from September 2015 to September 2018 were retrospectively analyzed. Patients meeting the inclusion and exclusion criteria were divided into two groups: Traditional single infusion (TSI group) and sequential infusion(SI group). The visual analog scale (VAS) and Oswestry disability index (ODI) were evaluated and compared, and duration of operation, bone cement content and complications were recorded.
Forty-five patients were included in this study, 24 in the TSI group and 21 in the SI group. The VAS and ODI were significantly different in both groups pre- and postoperatively. At the last follow-up, the VAS and ODI were not significantly different between the two groups compared with those at 1 wk postoperatively. The two groups had no significant differences in the VAS and ODI pre- and postoperatively and at the last follow-up. The leakage rate of bone cement was significantly lower in the SI group (14.3%, 3 of 21) than that in the TSI group (41.7%, 10 of 24).
Sequential infusion in unipedicular PVP is a safe and effective procedure for neu-rologically intact Kümmell’s disease, and this technique could decrease the incidence of bone cement leakage.
The role of sequential infusion in reducing the leakage of bone cement should be evaluated in a large sample multicenter randomized controlled study.
