Rib fractures are a common injury following blunt chest trauma, accounting for approximately 10% of all traumatic injuries and up to 50% of blunt chest trauma cases. These fractures are associated with a high risk of complications, such as pneumothorax, hemothorax, and pulmonary infections, and can significantly impact respiratory function. This study analyzes the risk factors for poor healing and long-duration pain in the conservative treatment of rib fractures, providing a reference for clinicians in choosing conservative treatment and formulating treatment plans. A retrospective analysis was conducted on 342 patients who underwent conservative treatment for rib fractures from January 2023 to May 2024. Baseline data, clinical data, and follow-up data were collected. Comparisons were made between the poor healing group and the good healing group, as well as between the long-duration pain group and the short-duration pain group in the conservative treatment of rib fractures. Univariate and multivariate logistic regression analyses were performed to identify risk factors for poor healing and long-duration pain. In patients undergoing conservative treatment for rib fractures, the average duration of pain was 12.18 ± 10.78 days, with an incidence of pulmonary complications of 59.06% (202/342) and poor healing rate of 6.43% (22/342). Significant differences were observed between the good and poor healing groups in terms of age (P = .018), presence of coronary heart disease (CHD, P = .023), chronic obstructive pulmonary disease (COPD, P < .001), blood calcium (P = .007), and alkaline phosphatase (P < .001). Similarly, significant differences were found between the long-duration and short-duration pain groups in age (P = .039), presence of diabetes (P < .001), CHD (P < .001), COPD (P < .001), and alkaline phosphatase (P < .001). Multivariate analysis identified COPD (P = .015), blood calcium (P = .013), and alkaline phosphatase (P = .006) as independent risk factors for poor healing, while diabetes (P = .001), CHD (P = .014), and alkaline phosphatase (P < .001) were independent risk factors for prolonged pain duration. COPD, blood calcium, and alkaline phosphatase are independent risk factors for poor healing in conservative treatment of rib fractures. Diabetes, CHD, and alkaline phosphatase are independent risk factors for long-duration pain in conservative treatment of rib fractures.
