Abstract

The present study aimed to evaluate the clinical efficacy of the bilateral pedicle cement anchoring technique combined with the postural reduction in percutaneous vertebroplasty (PVP) for Kümmell disease. For this purpose, a retrospective study was performed on 18 patients with Kümmell disease who between January 2018 and June 2021 underwent bilateral pedicle cement anchoring combined with postural reduction in PVP. Pre‑ and post‑operative bone mineral density, injected cement volume, visual analogue scale (VAS) values, Oswestry disability index (ODI) scores, Cobb angle measurements and anterior vertebral height (AVH) were recorded and assessed. The mean follow‑up duration was 8.4±1.2 months. The average VAS score decreased from 8.17±0.71 pre‑operatively to 1.56±0.62 post‑operatively and remained at 2.00±0.91 at the final follow‑up visit (P<0.05). The average ODI improved from 86.44±5.5 pre‑operatively to 24.33±7.82 post‑operatively. Until the last follow‑up, the ODI remained at 27.11±8.76 (P<0.05). Similarly, the changes in the Cobb angle and AVH before and after surgery were also statistically significant in the radiological evaluation (P<0.05). During the follow‑up, two patients experienced adjacent vertebral fractures. The loosening of cement was not found. Overall, the present study demonstrated that during the treatment of Kümmell disease with PVP, the bilateral pedicle cement anchoring technique combined with postural reduction can achieve good clinical outcomes.
