Brazil lacks registries on the prevalence of primary total hip arthroplasty (THA) fixation methods.
(i) to describe the demographic profile of patients who underwent THA in the public health system of the municipality of São Paulo during the last 12 years and (ii) to compare fixation methods regarding costs, hospital stay length, and death rates.
This is an ecological study conducted with data available on TabNet, a platform belonging to DATASUS. Public data (from the government health system) on THA procedures performed in São Paulo from 2008 to 2019 were extracted. Gender, age, city region, THA fixation method, number of surgeries, costs, hospital stay length, and death rates were analyzed.
We analyzed 7,673 THA, of which 6220 (81%) were performed via cementless/hybrid fixation and 1453 (19%), via the cemented technique. Cementless/hybrid fixation had a higher cost (US$ 495.27) than the cemented one (p < 0.001). Nevertheless, hospital stay length was 0.87 days longer for cemented fixation than the cementless/hybrid one. We found no significant difference in death rates between THA fixation methods.
THA cementless/hybrid fixation is prevalent in the municipality of São Paulo, which had higher total costs and shorter hospitalizations than cemented fixation. We found no difference between THA fixation methods and death rates.
巴西缺乏关于初次全髋关节置换术（THA）固定方法患病率的登记数据。
（i）描述过去12年在圣保罗市公共卫生系统接受THA手术的患者的人口统计学特征，以及（ii）比较不同固定方法在成本、住院时间和死亡率方面的差异。
这是一项基于TabNet平台（属于DATASUS）现有数据进行的生态学研究。提取了2008年至2019年在圣保罗市进行的THA手术的公共数据（来自政府卫生系统）。分析了性别、年龄、城市区域、THA固定方法、手术数量、成本、住院时间和死亡率。
我们分析了7673例THA手术，其中6220例（81%）采用非骨水泥/混合固定，1453例（19%）采用骨水泥技术。非骨水泥/混合固定的成本（495.27美元）高于骨水泥固定（p<0.001）。然而，骨水泥固定的住院时间比非骨水泥/混合固定长0.87天。我们发现THA固定方法之间的死亡率没有显著差异。
在圣保罗市，THA非骨水泥/混合固定较为普遍，其总成本高于骨水泥固定，住院时间更短。我们发现THA固定方法与死亡率之间没有差异。
