Rates and reasons for readmission and reoperation following adolescent pelvic osteotomy are not well-defined. This study aimed to (1) determine 30-day and 90-day readmission rates and the 2-year reoperation rate after pelvic osteotomy in adolescents and (2) identify reasons for readmission and reoperation. The Pediatric Health Information System database was queried between 10 January 2015 and 1 January 2020 for patients meeting selected International Classification of Diseases (ICD-10) procedure and diagnosis codes relating to pelvic osteotomies. Readmission rates were calculated within 30 and 90 days from index osteotomy. The ipsilateral reoperation rate was calculated within 2 years from index osteotomy. Reasons for these outcomes were identified. Univariate and multivariate analyses were utilized to identify readmission risks. Of 1475 patients, 5.4% and 9.2% were readmitted within 30 and 90 days, respectively. Reasons for readmission were consistent across both time points and included infection, hip-related orthopedic conditions and neurologic conditions. Younger age (OR 0.83, 95% CI: 0.76, 0.89; P < 0.0001) and male sex (OR 1.77, 95% CI: 1.23–2.54; P = 0.002) were predictive of readmission within 90 days. The 2-year reoperation rate was 32.1%, of which 79.8% underwent reoperation for hardware removal, 17.7% for revision and 1.3% for hip replacement. 30-day readmission, 90-day readmission and 2-year reoperation rates after adolescent pelvic osteotomy were 5.4%, 9.2% and 32.1%, respectively. Younger age and male sex were predictive of 90-day readmission. Most ipsilateral reoperations were for hardware removal. Understanding readmission and reoperation risks following pelvic osteotomy can benefit patient counseling and improve expectations of post-surgical outcomes. Level of Evidence: IV, case series.

青少年患者骨盆截骨术后再入院率和再手术率：评估儿科健康信息系统的数据库研究

青少年骨盆截骨术后再入院和再手术的发生率和原因尚不明确。本研究旨在 (1) 确定青少年骨盆截骨术后 30 天和 90 天再入院率和 2 年再手术率，以及 (2) 确定再入院和再手术的原因。在 2015 年 1 月 10 日至 2020 年 1 月 1 日期间，对符合选定国际疾病分类 (ICD-10) 程序和与骨盆截骨术相关的诊断代码的患者查询了儿科健康信息系统数据库。再入院率在指数截骨后 30 和 90 天内计算。同侧再手术率是在指数截骨后2年内计算的。确定了这些结果的原因。使用单变量和多变量分析来确定再入院风险。在 1475 名患者中，分别有 5.4% 和 9.2% 在 30 天和 90 天内重新入院。再次入院的原因在两个时间点都是一致的，包括感染、髋关节相关的骨科疾病和神经系统疾病。年龄较小（OR 0.83, 95% CI: 0.76, 0.89; P < 0.0001）和男性（OR 1.77, 95% CI: 1.23–2.54; P = 0.002）可预测 90 天内再入院。2年再手术率为32.1%，其中79.8%再次手术取出内固定，17.7%翻修，1.3%髋关节置换。青少年骨盆截骨术后30天再入院率、90天再入院率和2年再手术率分别为5.4%、9.2%和32.1%。年龄较小和男性可预测 90 天再入院。大多数同侧再手术是为了移除硬件。了解骨盆截骨术后再入院和再手术的风险可以有益于患者咨询并提高对术后结果的期望。证据级别：IV，案例系列。
