Abstract：Objective To explore the construction of a CT imaging feature and risk factor prediction model for elderly hip fractures based on bone density and clinical feature analysis. Methods Sixty elderly patients with hip fractures admitted to Lishui District People's Hospital in Nanjing from February 2020 to February 2023 were selected as the study group, and 50 elderly healthy volunteers who underwent physical examinations in our hospital during the same period were selected as the control group. Usually, quantitative CT methods are used to measure the CT values of bones and convert them into bone density values for analysis. Calculate the Z and T values of bone density in the hip and spine, and establish a predictive model to evaluate the risk of hip fractures in the elderly by analyzing clinical features such as bone density, age, gender, height, weight, BMI. Results CT imaging showed that women with decreased vBMD may be more prone to fractures, and the types of fractures may be more diverse. In patients with decreased vBMD, the soft tissue around the fracture may be more susceptible to damage;The results of univariate analysis showed that there were statistical differences between the two groups in terms of age, weight, height, BMI, hip bone density, spinal bone density Z values and T values (P<0.05). There were also statistical differences between different genders, lack of exercise, malnutrition, smoking and drinking, and family genetic history cases (P<0.05);The modeling analysis results showed that age, gender, weight, height, BMI, lack of exercise, malnutrition, smoking and drinking, family genetic history, spinal bone density Z value, and spinal bone density T value were all high-risk factors affecting elderly hip fractures (P<0.05). Conclusion By analyzing bone density and clinical features, we can better understand the CT imaging features and risk factors of hip fractures in the elderly, thereby improving the prediction and treatment effectiveness, predicting the risk of hip fractures in the elderly, and developing targeted preventive measures to reduce the risk of hip fractures.
