Abstract:
Introduction Open hand fractures are anecdotally reported to have lower infection rates than open long bone fractures. Although a 3-hour rule for antibiotic administration and a 6-hour rule for operative debridement have historically been upheld as ideal management for open fractures, other factors may be more influential in the development of infection. The purpose of this study was to investigate factors associated with open hand fracture infections. Materials and Methods We retrospectively reviewed 67 patients with 107 open hand fractures between 2012 and 2017. Time from injury to antibiotic administration and operative debridement, modified Gustilo-Anderson classification, and patient characteristics including age, smoking status, and presence of chronic disease were examined for each patient. Outcome parameters were the development of infection and fracture union. Results The overall rate of infection was 9% (6 of 67 patients). No type 1 or type 2 fractures developed infection in contrast to 12.2% of type 3 fractures. Patients who received antibiotics in less than 3 hours and underwent debridement in less than 6 hours did not have lower infection or nonunion rates than those who did not. The association between the modified Gustilo-Anderson classification and the development of infection or nonunion was statistically significant. Conclusion Factors including time to antibiotics, time to operative debridement, smoking status, and chronic disease comorbidities were not predictive of either infection or nonunion in open hand fractures. Fracture type as defined by a modified Gustilo-Anderson classification was the factor most strongly related to the development of infection or nonunion in these fractures.
Insights
The modified Gustilo-Anderson classification, not timing of antibiotics or debridement, significantly predicts infection and nonunion in open hand fractures. This finding challenges traditional management guidelines for these injuries.
Area of Science:
- Orthopedic Surgery
- Infectious Disease
- Trauma Care
Background:
- Open hand fractures are perceived to have lower infection rates than open long bone fractures.
- Traditional management emphasizes early antibiotic administration (≤3 hours) and operative debridement (≤6 hours) for open fractures.
- The influence of these time-dependent factors versus other variables on infection development in open hand fractures remains unclear.
Purpose of the Study:
- To investigate factors associated with the development of infection in open hand fractures.
- To identify predictors of infection and nonunion in open hand fractures.
- To evaluate the impact of traditional management timelines versus fracture classification on outcomes.
Main Methods:
- Retrospective review of 67 patients with 107 open hand fractures (2012-2017).
- Analysis of time to antibiotic administration and operative debridement.
- Assessment of modified Gustilo-Anderson classification, patient demographics, smoking status, and chronic diseases.
- Evaluation of infection and fracture union rates as outcome parameters.
Main Results:
- Overall infection rate was 9%; no infections occurred in Gustilo-Anderson type 1 or 2 fractures, versus 12.2% in type 3.
- No statistically significant difference in infection or nonunion rates was found based on antibiotic administration within 3 hours or debridement within 6 hours.
- The modified Gustilo-Anderson classification showed a statistically significant association with the development of infection and nonunion.
Conclusions:
- Time to antibiotic administration and operative debridement are not predictive of infection or nonunion in open hand fractures.
- Patient factors such as smoking status and chronic disease comorbidities did not significantly predict outcomes.
- Fracture severity, as determined by the modified Gustilo-Anderson classification, is the most significant factor related to infection and nonunion in open hand fractures.

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...
