Objective To analyze the distribution of pathogenic bacteria in postoperative wound infection and related influencing factors in patients undergoing bone and joint surgery. Methods 928 patients who underwent bone and joint surgery in the Department of Orthopedics of our hospital from January 2021 to December 2023 were selected and divided into infected group and non-infected group according to whether wound infection occurred after surgery. The distribution of pathogenic bacteria and risk factors of wound infection after bone and joint surgery were analyzed. Results In 21 patients with postoperative wound infection, 52 strains of pathogenic bacteria were isolated. Gram-positive bacteria accounted for 71.15%, gram-negative bacteria accounted for 25.00%, and fungi accounted for 3.85%. Multivariate Logistic regression analysis showed that age ≥65 years, long-term use of hormones, and operation time ≥2 hours were risk factors for postoperative wound infection (P<0.05). Conclusion The main pathogens of wound infection in bone and joint surgery are gram-positive bacteria. The risk factors of infection include age ≥65 years, long-term use of hormones, and operation time ≥2h.
