Timing of Olecranon Fracture Fixation Does Not Affect Early Complication or Reoperation Rates.

Purpose: Surgical fixation of olecranon fractures can lead to soft-tissue complications and return to the operating room for hardware removal. While some risk factors of complications after olecranon fracture fixation have been described, the effects of fixation timing on complications and reoperation have not been evaluated. The purpose of the present study was to assess whether the timing of olecranon fracture fixation affects complication and reoperation rates. Methods: All patients who underwent olecranon fracture open reduction and internal fixation at a single level 1 trauma center from January 2012 to February 2022 were included in the study. A retrospective review was performed to evaluate patients for inclusion and to identify patient demographic factors, medical comorbidities, concomitant injuries, mechanism of injury, and time to fixation. Operative and clinical notes were evaluated to identify fixation type and outcomes of interest. Patients were stratified into early, standard, and delayed fixation groups (0-3 days, 4-14 days, and >14 days, respectively) for independent analyses, and Fisher's exact test was used to identify differences in complications and reoperations between groups. Multivariate analysis was used to assess associations between patient demographic factors, complication rates, and time to surgery. Results: A total of 97 patients met inclusion criteria of having an olecranon open reduction and internal fixation and had a minimum follow-up of at least 10 weeks, with an average follow-up of 7.1 months. The average time to surgery in the overall cohort was 9.3 days. There were no differences in the number of total complications and rate of reoperation among the three cohorts. Smoking was found to be significantly associated with total complications, while open fracture was significantly associated with reoperation. Polytrauma and open fracture were significantly associated with earlier operation, while smoking was significantly associated with delayed fixation. Conclusions: The timing of fixation of displaced olecranon fractures does not significantly increase the rate of early complications or reoperation. Type of study/level of evidence: Symptom Prevalence Study III.
