PurposeWe aimed to present our experience in anchoring technique and evaluate the efficacy and safety of unilateral percutaneous vertebroplasty in patients with neurologically intact Kümmell's disease.MethodsFrom January 2014 to December 2017, 29 patients (17 males and 12 females) with neurologically intact Kümmell's disease were operated on using anchoring technique in unilateral percutaneous vertebroplasty (PVP). Ages of the enrolled patients ranged from 67 to 81 years (mean 73.8 years). Clinical efficacy was evaluated by back pain visual analogue scale (BP-VAS) score, Oswestry disability index (ODI) score, as well as the height of anterior border and the kyphotic angle of the involved vertebral body on a standing lateral radiograph. The safety of PVP was assessed by surgical-related complications, including bone cement leakage and neurological deficit.ResultsAll 29 patients underwent the PVP procedure successfully. The mean operation time was 35 ± 12 min. And all patients were able to walk/ambulate with a thoracolumbar brace after 12 to 24 hours, staying in bed postoperatively. Significantly statistical differences were observed in both BP-VAS and ODI scores at each time point of follow-up when compared with the preoperative condition (P < 0.05). Besides, statistically significant improvement in radiographic measurements such as kyphotic angle and the height of the anterior border of the involved vertebral body between the preoperative and postoperative assessments was also observed (P < 0.05) and asymptomatic leakage of cement occurred in 7 of 29 cases (24.1%).ConclusionsWe considered that the anchoring technique in unilateral PVP could provide an effective and safe alternative for neurologically intact Kümmell's disease.Copyright © 2020 Rongqing Qin et al.
