Purpose
The purpose of this study was to determine the rates of compartment syndrome and other early complications following outpatient open reduction and internal fixation (ORIF) of tibial plateau fractures.
Methods
This was a retrospective cohort at a single US level I academic trauma centre of patients with tibial plateau fractures managed operatively. Inpatients received their definitive ORIF during their index hospital stay and were admitted post-operatively following ORIF. Outpatients were scheduled for ambulatory surgery during definitive ORIF. Exclusion criteria for outpatient surgery included compartment syndrome, polytrauma, open types IIIb/IIIc, and patients who received any internal fixation during index presentation. The primary outcome measure was post-operative compartment syndrome. Secondary outcomes were return to the 90-day return to the ED, 90-day readmission, surgical wound infection, thromboembolism, and 90-day mortality. An intention-to-treat (ITT) and as-treated (AT) analyses were performed.
Results
Totally, 71 inpatients and 47 outpatients were included. There were no cases of post-operative compartment syndrome. In the ITT analysis, there were no differences for inpatients vs outpatients for 90-day re-admission (22.5% vs 12.8%, p = 0.275), 90-day return to the ED (35.2% vs 17.0%, p = 0.052), infection (12.7% vs 2.1%, p = 0.094), DVT (7% vs 4.3%, p = 0.819), or PE 1.4% vs 0.0%, p = 1.000). The AT analysis showed a significantly higher 90-day re-admission (26.9% vs 2.5%, p = 0.003) and 90-day ED visit (38.5% vs 7.5%, p = 0.001) rate in the inpatient group.
Conclusions
Appropriately selected patients with isolated tibial plateau fractures can have non-inferior rates of compartment syndrome and post-operative complications when compared to inpatients.
