Abstract
ObjectiveThis study introduces a minimally invasive technique for efficient three-column reconstruction, augmentation, and stabilization of osteoporotic thoracolumbar burst fractures (OTLBFs).MethodsSixty-eight patients with OTLBFs and no neurological deficits were included from July 2019 to September 2020. The patients were divided into two groups: the simple percutaneous kyphoplasty (PKP) group (n = 32) and the percutaneous kyphoplasty combined with pediculoplasty (PKCPP) group (n = 36). The clinical and radiological outcomes were assessed during a minimum 1-year follow-up period. Clinical outcomes were assessed via the visual analog scale (VAS) and modified MacNab grading criteria. The radiological outcomes included the Cobb angle (CA), anterior wall height (AWH), and posterior wall height (PWH). The surgery duration, postoperative analgesic dosage, length of hospital stay, and complications were recorded.ResultsSurgery duration was not significantly different between the two groups (P > 0.05). The PKCPP group had a lower analgesic dosage and shorter hospital stay (P < 0.05). Postoperatively, the PKCPP group exhibited better VAS scores and modified MacNab scale scores (P < 0.05), but the differences at the last follow-up assessment were not significant (P > 0.05). Postoperative CA, AWH, and PWH correction were not significantly different on the first postoperative day (P > 0.05). However, the PKCPP group had significantly less CA and PWH loss of correction at the last follow-up visit (P < 0.05). The PKCPP group had significantly fewer complications (P < 0.05).ConclusionsThe PKCPP technique complements simple PKP for OTLBFs. It quickly relieves pain, maintains the vertebral body height and Cobb angle, ensures cement stabilization, and offers more stable three-column support.
