Abstract: Objective To analyze the case characteristics and complications of hip fracture in Tangshan City, and provide reference for the prevention and treatment of hip fracture. Methods The descriptive epidemiological analysis was used to analyze the characteristics and complications of adult cases of hip fracture treated in three hospitals in Tangshan City from January 2018 to January 2023, and the influencing factors of complications were analyzed by univariate and multivariate analysis methods. Results A total of 7 953 patients with hip fracture were included, including 1 527 cases in 2018, 1 562 cases in 2019, 1 594 cases in 2020, 1 629 cases in 2021, and 1 641 cases in 2022, showed an increasing trend year by year. The proportion of female patients with hip fracture was 52.96%, which was higher than that of male patients （47.04%）. The number of fracture patients increased with age, and the number of patients aged 80-92 years was the highest, accounting for 25.56%. Spring and winter were the most common seasons for hip fracture, accounting for 26.32% and 32.48% respectively. The main fracture type was femoral neck fracture, accounting for 39.66%. Among the causes of fracture, the proportion of falling patients was the highest, accounting for 47.88%. The proportion of patients with open fractures was 52.80%, which was significantly higher than that of patients with closed fractures （47.20%）. Surgical treatment was the main treatment, accounting for 93.66%. In addition, 64.14% of the patients were complicated with osteoporosis. A total of 513 patients had complications during hospitalization, with an incidence rate of 6.45%. Multivariate logistic regression analysis showed that age （OR=6.166）, open fracture （OR=3.611）, the time from fracture to hospital >48 hours （OR=3.728）, sonservative treatment （OR=6.443）, and types of comorbidities （1-2 OR=2.983, ≥3 OR=5.540） were the influencing factors for the occurrence of complications in patients with hip fractures. Conclusions The majority of hip fracture patients in Tangshan are elderly patients, and femoral neck fracture and intertrochanteric fracture are common types. Age, open fracture, time from fracture to hospital, conservative treatment, and number of comorbidities are the main factors affecting the incidence of complications.
