METHODS: The 2010-2022 Pearldiver M161 dataset was queried for those who were 10 to 18 years old with AIS undergoing PSF with at least 10 years follow-up. Patient characteristics were abstracted. Reoperations were identified based on coding for any subsequent thoracic/lumbar surgery/revision. The 10-year reoperation rate and reasons for reoperation were determined, and multivariate regression was performed to determine risk factors.
RESULTS: In total, 3,373 AIS PSF patients were identified. Of the study cohort, 324 (9.6%) underwent reoperation within 10-years with an interquartile range for timing of surgery of 81-658 days, of which 29.6% were done for infection. Reoperations were done within the first three months for 152 (46.9% of reoperations), three months to 2 years for 97 (29.9%), and 2 years to 10 years for 74 (22.8%). Based on multivariate regression, need for reoperation was associated with male sex (OR: 1.70), asthma (OR: 1.36) and greater than thirteen segments of instrumentation (OR: 1.48) (p < 0.05 for each) but not age, other comorbidities, or insurance.
CONCLUSIONS: The current study of a large national AIS PSF population found 9.6% to undergo reoperation in the 10 years following their index operation. Although specifics about the curve pattern could not be determined, the reoperation incidence and correlation with specific risk factors are notable and important for patient counselling.
方法:查询了2010-2022PearldiverM161数据集,查询了10至18岁的AIS患者,并进行了至少10年的随访。提取患者特征。根据任何后续胸/腰椎手术/翻修的编码确定了再次手术。确定了10年再手术率和再手术原因,并进行多因素回归以确定危险因素。
结果:总计,确定了3,373名AISPSF患者。在研究队列中,324(9.6%)在10年内进行了再次手术,四分位数范围为81-658天,其中29.6%为感染。在前三个月内进行了152次再手术(占再手术的46.9%),97个月至2年(29.9%),和2年至10年的74(22.8%)。基于多元回归,再次手术的需要与男性相关(OR:1.70),哮喘(OR:1.36)和大于13段的仪器(OR:1.48)(每个p<0.05),但不是年龄,其他合并症,或保险。
结论:当前对一个大型国家AISPSF人群的研究发现,在他们的指数手术后的10年内,有9.6%的人接受了再次手术。虽然关于曲线模式的细节无法确定,再次手术发生率和与特定危险因素的相关性对于患者咨询非常重要。
