Impact of Time to Fixation on Outcomes of Operative Treatment of Intra-articular Distal Radius Fractures.

Abstract

Background: The incidence of operative treatment of distal radius fractures (DRFs) has increased recently, but the optimal timing for surgical fixation remains unclear. We hypothesized that: (1) an increase in time to fixation of intra-articular DRFs would increase the likelihood of postoperative complications; and (2) increased time from injury to fixation would lead to longer surgical time and worse range of motion (ROM) outcomes.

Methods: We retrospectively reviewed 299 fractures in 284 adult patients who underwent open reduction and internal fixation (ORIF) of a closed, intra-articular DRF at our institution over a 10.5-year period. Demographic information, time to surgery (TTS) from injury, surgical time, tourniquet time, complications, and final postoperative ROM were collected for logistic regression modeling to predict the risk of postoperative complication.

Results: Twenty-seven (9.0%) patients experienced postoperative complications. The median TTS (Q1-Q3) for all patients was 7.0 (4.0-12.0) days. Patients who experienced an early postoperative complication had significantly longer median TTS (10.0 days) than those who did not (7.0 days). Patients with longer TTS were more likely to experience a complication (odds ratio, 1.11; 95% confidence interval, 1.04-1.19; P = .006). Tourniquet time and final wrist ROM were not related to TTS. A logistic regression analysis found that early complication rate doubles at 7.0 days after injury (from 3.5% to 6.9%).

Conclusions: Patients with operative intra-articular distal radius fractures should ideally be fixed within 7 to 10 days of injury to minimize the risk of early postoperative complications. The tourniquet time and final ROM were not associated with time to surgery.
