Epidemiological and clinical parameters according to the Parker-Palmer Index (PPI) have not been specifically studied as predictors of re-fracture time in patients over 65 years old with contralateral hip fracture. The main purpose of this study was to assess whether these parameters could represent a prognostic factor in this population.
This retrospective study included all consecutive patients older than 65 years that suffered from a proximal femoral fracture, 31 according to Association for Osteosynthesis/Orthopaedic Trauma Association classification, treated at our unit between Feb 1st 2019 and Feb 1st 2020.
This study enrolled 387 patients. Thirty-seven of them had already incurred a contralateral hip fracture: seven males and 30 females. The median time between the first and second hip fractures was 3.5 years. This study revealed that increasing age (p = 0.003), male sex (p = 0.029) and a PPI value ≥ 5 between the first and second hip fracture (p = 0.015) are risk factors associated with a contralateral hip fracture in the first three years after the first episode. There were no statistically significant differences regarding anti-osteoporotic therapy and the anatomic site of the first hip fracture episode.
The results of the present study suggest that several risk factors have a crucial role in hip re-fracture time in patients over 65 years old.
根据帕克-帕尔默指数（PPI）的流行病学和临床参数尚未被专门研究为 65 岁以上伴有对侧髋部骨折患者再骨折时间的预测因素。本研究的主要目的是评估这些参数是否可以成为该人群的预后因素。
这是一项回顾性研究，纳入了 2019 年 2 月 1 日至 2020 年 2 月 1 日期间在我院治疗的 31 例按骨折协会/骨科创伤协会分类的股骨近端骨折且年龄大于 65 岁的连续患者。
本研究共纳入 387 例患者。其中 37 例患者已发生对侧髋部骨折：7 例男性和 30 例女性。首次和第二次髋部骨折之间的中位数时间为 3.5 年。本研究表明，年龄增加（p=0.003）、男性（p=0.029）和首次和第二次髋部骨折之间的 PPI 值≥5（p=0.015）是首次发作后三年内发生对侧髋部骨折的相关危险因素。抗骨质疏松治疗和首次髋部骨折的解剖部位之间无统计学显著差异。
本研究结果表明，在 65 岁以上患者中，几个危险因素在髋部再骨折时间中起着关键作用。
