Abstract：
BACKGROUND: Gluteal muscle fatty atrophy (gMFA) might impair pelvic stability and negatively influence remobilization in patients with fragility fractures of the pelvis (FFP). This study aimed to investigate the association between gMFA and surgical indication in patients with FFP.
METHODS: A retrospective analysis of 429 patients (age ≥80) diagnosed with FFP was performed. gMFA of the gluteus maximus, medius, and minimus was evaluated using a standard scoring system based on computer tomography images.
RESULTS: No significant difference was found in gMFA between genders or among FFP types. The severity of gMFA did not correlate with age. The severity of gMFA in the gluteus medius was significantly greater than in the gluteus maximus, whereas the most profound gMFA was found in the gluteus minimus. gMFA was significantly more severe in patients who underwent an operation than in conservatively treated patients with type-III FFP, and an independent correlation to surgical indication was found using logistic regression.
CONCLUSIONS: Our findings imply that gMFA is an independent factor for surgical treatment in patients with type-III FFP. Besides focusing on the fracture pattern, the further evaluation of gMFA could be a feasible parameter for decision making toward either conservative or surgical treatment of type-III FFP.

摘要：
背景：对于骨盆脆性骨折（FFP）患者，臀肌脂肪萎缩（gMFA）可能会损害骨盆稳定性并对其再固定产生负面影响。本研究旨在探讨gMFA与FFP患者手术指征之间的关系。
方法：对429例诊断为FFP的患者（年龄≥80岁）进行回顾性分析。臀大肌的gMFA，Medius,和最小值使用基于计算机断层扫描图像的标准评分系统进行评估。
结果：性别之间或FFP类型之间的gMFA没有发现显着差异。gMFA的严重程度与年龄无关。臀中肌gMFA的严重程度明显大于臀大肌，而最深刻的gMFA是在臀小肌中发现的。接受手术的患者的gMFA比保守治疗的III型FFP患者的gMFA严重，并且使用逻辑回归发现与手术指征的独立相关性。
结论：我们的发现暗示gMFA是III型FFP患者手术治疗的独立因素。除了关注断裂模式，进一步评估gMFA可能是III型FFP保守或手术治疗决策的可行参数.
