- Abstract
Purpose: To analyze the association between scoliosis and vertebral refracture after percutaneous kyphoplasty (PKP) in patients with osteoporotic vertebral compression fractures (OVCFs). Methods: A retrospective study was conducted on 269 patients meeting the criteria from January 2014 to October 2022. All patients underwent PKP with complete data and were followed-up for > 12 months. First, it was verified that scoliosis was a risk factor in 269 patients. Second, patients with scoliosis were grouped based on the Cobb angle to evaluate the impact of the post-operative angle. The cox proportional hazards regression analysis and survival analysis were used to calculate the hazard ratio and recurrence time. Results: A total of 56 patients had scoliosis, 18 of whom experienced refractures after PKP. The risk factors for vertebral refractures included a T-score < − 3.0 and presence of scoliosis (both p < 0.001). The results indicated that the vertebral fractured arc (T10 − L4) was highly influential in scoliosis and vertebral fractures. When scoliotic and initially fractured vertebrae were situated within T10 − L4, the risk factors for vertebral refracture included a postoperative Cobb angle of ≥ 20° (p = 0.002) and an increased angle (p = 0.001). The mean recurrence times were 17.2 (10.7 − 23.7) months and 17.6 (7.9 − 27.3) months, respectively. Conclusion: Osteoporosis combined with scoliosis significantly increases the risk of vertebral refractures after PKP in patients with OVCFs. A postoperative Cobb angle of ≥ 20° and an increased angle are significant risk factors for vertebral refractures when scoliotic and initially fractured vertebrae are situated within T10 − L4.
