Background: Infection following surgical fixation of a distal radius fracture can markedly compromise a patient's functional outcome. This study aimed to compare infection rates in pediatric (5-14 years) and adolescent (15-17 years) patients undergoing fixation of a distal radius fracture to a cohort of young adult (18-30 years) patients.
Methods: A matched retrospective study was performed using PearlDiver to determine the rates of postoperative infection following distal radius fixation. χ2 and logistic regression were used to assess differences in rates, while linear regression was used to analyze rates of infection over time.
Results: In 32 368 patients, young adults experienced postoperative infection at a significantly increased rate (odds ratio [OR] = 1.81; 95% confidence interval [CI], 1.45-2.27). This trend was consistent among the male (OR = 1.96; 1.49-2.57) and female (OR = 2.11, 1.37-3.27) cohorts. In the multivariate model, the adult cohort remained at increased risk (OR = 1.40; 95% CI, 1.04-1.89), with open fracture (OR = 4.99; 3.55-6.87), smoking (OR = 1.76; 1.22-2.48), hypertension (OR = 1.69; 1.20-2.33), and obesity (OR = 1.37; 1.02, 1.80) identified as other significant risk factors. There was no significant change in the rate of postoperative infections over the 11-year study period.
Conclusion: This study demonstrated that although surgical site infections following distal radius fixation are low in patients aged 30 years or younger (0.97%), young adults develop infections at a significantly increased rate. This is important for surgeons to recognize when counseling patients on the risks of surgical fixation.
