Background:
Lower extremity (LE) open fractures are difficult wounds to manage, oftentimes requiring flap reconstruction. These procedures involve complex recoveries that impact daily function and quality of life, with early weight-bearing progression as a key milestone in recovery. Few studies have examined how factors influence weight-bearing progression in patients undergoing flap reconstruction after traumatic LE open fractures.
Methods:
All patients > 18 years old between 2012 and 2024 who presented with a Gustilo III or higher LE open fracture and underwent flap reconstruction at our level 1 trauma center were analyzed. Individual-level sociodemographic factors assessed included race/ethnicity, age, sex, primary language, and insurance status. Neighborhood-level factors, including median income, employment rate, and distance from trauma center, were derived from Zip Code Tabulation Areas. Primary outcome was time to weight bearing as tolerated (WBAT). Secondary outcomes included minor complications (not requiring reoperation) and major complications (requiring reoperation). Multivariate analyses were performed.
Results:
A total of 324 patients were included. Of these, 298 patients (92%) had documented clearance for weight bearing and were included in the WBAT analysis. The median time to WBAT was 88 days (interquartile range: 55-137). Non-English-speaking patients had significantly shorter times to WBAT (exp (β) = 0.66, 95% CI: 0.47-0.92, p = 0.01). No neighborhood-level SES variables were associated with time to WBAT, and no individual- or neighborhood-level sociodemographic factors were significantly associated with complication rates.
Conclusion:
Non-English-speaking patients achieved WBAT clearance sooner than English-speaking patients. This counterintuitive finding, in the absence of other individual- or neighborhood-level associations, may reflect unmeasured social and financial pressures influencing postoperative recovery milestones.

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 procedure...
