The present study evaluated the frequency of periprosthetic fractures and tested the hypothesis that this population's demographics and outcomes are unique as compared with other arthroplasty patients. The National Hospital Discharge Survey provided the raw data. Individuals admitted with a primary TKA, primary THA, or revision TJA were selected. Annual rates were then calculated and demographics and outcomes compared. 30,624 patients were reviewed. The proportion of admissions for periprosthetic fractures ranged from 4.2% to 7.4% annually. As compared to patients admitted for other TJA diagnoses, individuals admitted with periprosthetic fracture were older, were more often female, were more often admitted emergently/urgently, had longer lengths of stay, had higher rates of discharge to places other than home, and had a significantly elevated mortality.
本研究评估了假体周围骨折的频率，并检验了以下假设，即与其他关节置换患者相比，该人群的人口统计学特征和结果是独特的。国家医院出院调查提供了原始数据。选择因初次 TKA、初次 THA 或翻修 TJA 而入院的患者。然后计算了每年的发生率，并比较了人口统计学特征和结果。共回顾了 30624 名患者。假体周围骨折的入院比例每年从 4.2%到 7.4%不等。与因其他 TJA 诊断而入院的患者相比，因假体周围骨折而入院的患者年龄更大，女性更多，更常紧急/紧急入院，住院时间更长，出院到非家庭场所的比例更高，死亡率显著升高。
