Summary
Fracture blisters, fluid-filled skin sacs over fractures, are linked to surgical timing. Early surgery (within 24 hours) for acute fractures reduces their incidence, improving patient care outcomes.
Area of Science:
- Orthopedic Surgery
- Trauma Care
- Dermatology
Background:
- Fracture blisters are poorly documented skin vesicles overlying fractures.
- Objective data on their characteristics and management is scarce.
- Understanding fracture blisters is crucial for trauma patient care.
Purpose of the Study:
- To retrospectively analyze the characteristics and incidence of fracture blisters.
- To investigate the relationship between surgical timing and fracture blister development.
- To evaluate the impact of fracture blisters on patient care and surgical management.
Main Methods:
- Retrospective study of 53 fracture blisters in 51 patients across four hospitals (three Level I trauma centers).
- Analysis of blister occurrence, location, timing, and association with surgical intervention (ORIF).
- Evaluation of patient care impact, including surgical delays, plan changes, and wound infections.
Main Results:
- Fracture blisters commonly occurred on the tibia, ankle, and elbow within 24-48 hours of injury.
- Early ORIF (within 24 hours) significantly reduced fracture blister incidence (2.0% vs. 8.0%).
- Blisters present at surgery affected patient care in 71% of cases, leading to delays or infections.
Conclusions:
- Early surgical intervention for acute fractures minimizes fracture blister formation.
- Fracture blisters can complicate surgical management and increase infection risk.
- Fracture blisters are subepidermal vesicles containing sterile transudate; rupture can lead to secondary colonization.
