Objectives:
To investigate whether discharge between stages for lower extremity periarticular fracture surgery affected complication rates and hospital length of stay. It was hypothesized that patients discharged between stages experienced more complications and readmissions but shorter duration of hospitalization.
Design:
Retrospective.
Setting:
Single academic Level 1 trauma center.
Patient Selection Criteria:
Patients with tibial plateau (AO/OTA 41B/C) and pilon (43B/C) fractures treated in staged fashion were included.
Outcome Measures And Comparisons:
Patients were grouped by whether they were discharged or remained admitted (hospitalized) between stages. Patient factors, total duration of stay, time between stages, and complications were evaluated and compared.
Results:
A total of 102 patients were included in the study (mean age = 44.0 (range 14-75); 63.7% male). Of these, 28 were discharged between stages (mean age = 45.5 (range 17-75); 60.7% male), while 74 remained admitted (mean age = 43.4 (range 14-75); 64.9% male). There were no differences between the groups regarding age ( P = 0.548), sex ( P = 0.697), body mass index (30.8 vs. 30.5, P = 0.839), homelessness (7.1% vs. 20.3%, P = 0.143), diabetes (3.6% vs. 12.2%, P = 0.278), smoking status (32.1% vs. 37.8%, P = 0.593), substance use (21.4% vs. 41.9%, P = 0.055), OTA/AO classification ( P = 0.721), or Gustilo-Anderson classification ( P = 0.452). The hospitalized group had a higher mean Injury Severity Score (12.6 vs. 6.6, P < 0.001). Discharged patients had higher rates of pin-site infection that occurred between stages (14.3% vs. 2.7%, P = 0.047), longer time between stages (17.5 vs. 10.8 days, P < 0.001), and shorter combined total hospital length of stay (7.1 vs. 22.6 days, P < 0.001). There was no difference in rates of nonunion (9.1% vs. 13.7%, P = 0.719), deep infection (18.2% vs. 25.9%, P = 0.566), superficial infection (9.1% vs. 3.4%, P = 0.303), and unplanned reoperation (36.4% vs. 36.2%, P = 1.000) between the groups.
Conclusions:
Patients with tibial plateau and pilon fractures who were discharged home between external fixation and definitive fixation had more temporary pin-site infections and longer time between stages, but no increase in long-term complications and spent fewer total days in the hospital than patients who remained hospitalized between stages. The group of patients who remained hospitalized between stages had a higher mean injury severity score.
Level Of Evidence:
Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
