Abstract：
OBJECTIVE: Determine if anterior internal versus supra-acetabular external fixation of unstable pelvic fractures is associated with care needs or discharge.
METHODS: A retrospective cohort study was performed at two tertiary trauma referral centers. Adults with unstable pelvis fractures (AO/OTA 61B/61C) who received operative fixation of the anterior and posterior pelvic ring by two orthopedic trauma surgeons from October 2020 to November 2022 were included. The primary outcome was discharge destination. Secondary outcomes included intensive care unit (ICU) or ventilator days, length of stay, and hospital charges.
RESULTS: Eighty-three eligible patients were 38.6% female, with a mean age of 47.2 ± 20.3 years and BMI 28.1 ± 6.4 kg/m2. Fifty-nine patients (71.1%) received anterior pelvis internal fixation and 24 (28.9%) received external fixation. External fixation was associated with weight-bearing restrictions (91.7% versus 49.2%, p = 0.01). No differences in demographic, functional status, insurance type, fracture classification, or injury severity measures were observed by treatment. Internal versus external anterior pelvic fixation was not associated with discharge to home (49.2% versus 29.2%, p = 0.10), median ICU days (3.0 [interquartile range (IQR) 7.8 versus 5.5 [IQR 4.3], p = 0.14, ventilator days (0 [IQR 6.0] versus 0 [IQR 2.8], p = 0.51), length of stay (13.0 [IQR 13.0] versus 17.5 (IQR 20.5), p = 0.38), or total hospital charges (US dollars 180,311 [IQR 219,061.75] versus 243,622 [IQR 187,111], p = 0.14).
CONCLUSIONS: Anterior internal versus supra-acetabular external fixation of unstable pelvis fractures was not significantly associated with discharge destination, critical care, hospital length of stay, or hospital charges. This sample may be underpowered to detect differences between groups.
METHODS: Therapeutic Level IV.

摘要：
目的：确定不稳定骨盆骨折的前路内固定与髋臼上外固定是否与护理需求或出院相关。
方法：在两个三级创伤转诊中心进行了一项回顾性队列研究。包括2020年10月至2022年11月由两名骨科创伤外科医师对骨盆前后环进行手术固定的不稳定骨盆骨折（AO/OTA61B/61C）的成年人。主要结果是出院目的地。次要结局包括重症监护病房（ICU）或呼吸机天数，逗留时间,和医院费用。
结果：83名符合条件的患者为38.6%的女性，平均年龄为47.2±20.3岁，BMI为28.1±6.4kg/m2。59例（71.1％）接受前路骨盆内固定，24例（28.9％）接受外固定。外固定与负重限制相关(91.7%对49.2%,p=0.01)。人口没有差异，功能状态，保险类型,断裂分类,或通过治疗观察损伤严重程度。骨盆前路内固定与外固定与出院无关（49.2%对29.2%，p=0.10),ICU天数中位数（3.0[四分位数间距（IQR）7.8对5.5[IQR4.3]，p=0.14，呼吸机天数(0[IQR6.0]对0[IQR2.8]，p=0.51),住院时间（13.0[IQR13.0]对17.5（IQR20.5），p=0.38)，或医院总费用（180,311美元[IQR219,061.75]对243,622美元[IQR187,111]，p=0.14）。
结论：不稳定骨盆骨折的前路内固定与髋臼上外固定与出院目的地无显著相关，重症监护,住院时间,或医院费用。该样本可能不足以检测组之间的差异。
方法：治疗级别IV。
