Objectives:
To determine the effect of intramedullary screw-based fixation on early postoperative complications after olecranon fractures. We hypothesized that intramedullary screw-based fixation results in decreased need for reoperation compared with plate and screw-based and tension band-based fixation.
Design:
Retrospective cohort.
Setting:
Two academic Level-1 trauma centers.
Patients/Participants:
Five hundred fifty-six patients treated with a tension band-based, plate and screw-based, or intramedullary screw-based construct for an olecranon fracture over a 10-year period.
Intervention:
Open reduction and internal fixation.
Main Outcome Measurement:
Unplanned reoperation. Demographic, injury type and severity, supplemental fixation, and length of follow-up data were viewed as potential confounders and analyzed as such.
Results:
We identified 556 relevant patients. One hundred ninety-nine patients were treated with an intramedullary screw-based construct, 229 with a plate and screw-based construct, and 128 with a tension band-based construct. We observed significant differences in the age, fracture type, percentage of open fractures, use of supplemental fixation, and treating institution between the treatment groups. Ninety-five patients (17.1%) had an unplanned reoperation. When we adjusted for confounders, intramedullary screw-based fixation reduced the odds of an unplanned reoperation by 54% compared with plate and screw-based treatment. In the adjusted analysis, we did not observe a difference between plate and screw-based treatment and tension band-based fixation.
Conclusions:
Intramedullary screw-based fixation of olecranon fractures results in decreased need for early reoperation compared with more common olecranon fixation strategies.
Level Of Evidence:
Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.
