The authors hypothesized that age, body mass index (BMI), and medical comorbidities (graded with the Charleson Comorbidiy index [CCI]) could be used to predict early complications after TSA. The authors performed a retrospective review of primary TSAs with a minimum of 90-day follow-up. One hundred twenty-seven patients met the inclusion criteria. Complications occurred in 12 (9.4%) of patients. Major complications occurred in 1 patient (0.8%), medical in 8 (6.3%), and surgical in 4 (3.1%). CCI significantly correlated with complication rates and multivariate regression analysis demonstrated CCI to be the only significant determinant of overall complication rates (P = 0.005) and medical complication rates (P = 0.015). While BMI subgroup did not affect complication rates, transfusion rates, intra-operative blood loss, or operative time, our study may have been underpowered for this variable.
作者假设年龄、体重指数（BMI）和合并症（用 Charlson 合并症指数[CCI]进行分级）可用于预测 TSA 后的早期并发症。作者对至少有 90 天随访的初次 TSA 进行了回顾性分析。127 名患者符合纳入标准。12 名（9.4%）患者发生并发症。1 名（0.8%）患者发生重大并发症，8 名（6.3%）患者发生内科并发症，4 名（3.1%）患者发生外科并发症。CCI 与并发症发生率显著相关，多变量回归分析表明 CCI 是总并发症发生率（P=0.005）和内科并发症发生率（P=0.015）的唯一显著决定因素。虽然 BMI 亚组并不影响并发症发生率、输血率、术中失血量或手术时间，但我们的研究可能对该变量的效能不足。
