There is concern about safety of bilateral total hip arthroplasty (THA).This study aims to compare in-hospital complication rates between unilateral, simultaneous and staged bilateral THAs. The Nationwide Inpatient Sample from 2002-2010 was used. Patients and complications were identified using ICD-9-CM codes. In multivariate analysis, bilateral THA had higher risk of systemic complications (Odds ratio (OR): 2.1, P<0.001) compared to unilateral procedure, whereas no significant difference existed between simultaneous and staged bilateral THAs. The rate of local complications was higher in bilateral versus unilateral (4.96% versus 4.54%, P=0.009) and in staged versus simultaneous bilateral THAs (OR: 1.75, P=0.05). Bilateral THA increases risk of systemic complications compared to unilateral surgery and simultaneous bilateral THA appears to be safer than staging during one hospitalization.
双侧全髋关节置换术（THA）的安全性备受关注。本研究旨在比较单侧、同期和分期双侧THA的院内并发症发生率。使用了2002年至2010年的全国住院患者样本。通过ICD-9-CM编码识别患者和并发症。在多变量分析中，与单侧手术相比，双侧THA发生全身并发症的风险更高（优势比（OR）：2.1，P<0.001），而同期和分期双侧THA之间无显著差异。双侧THA的局部并发症发生率高于单侧（4.96%对4.54%，P=0.009），分期双侧THA高于同期双侧THA（OR：1.75，P=0.05）。与单侧手术相比，双侧THA增加了全身并发症的风险，同期双侧THA在一次住院期间似乎比分期更安全。
