Analysis of acute extremity compartment syndrome using a genealogic population database

Area of Science:

• Orthopedic Surgery
• Trauma Surgery
• Epidemiology

Background:

• Acute extremity compartment syndrome (CS) is a severe condition in trauma patients with limited research.
• Understanding CS incidence and risk factors is crucial for improving patient outcomes.

Purpose of the Study:

• To analyze the incidence and risk factors of extremity CS using a large statewide hospital database.
• To investigate the potential heritable risk for CS.

Main Methods:

• Retrospective analysis of adult patients with tibia, femur, or upper extremity fractures (1996-2020).
• Comparison of cohorts with and without CS diagnosis to identify risk factors via logistic regression.
• Evaluation of long-term mortality risk using Cox proportional hazard modeling and heritability analysis.

Main Results:

• CS incidence was 0.59% among 158,624 fractures.
• Significant risk factors for CS included male sex, younger age, Medicaid enrollment, and smoking.
• CS diagnosis was associated with increased long-term mortality (RR=1.61).
• No significant heritable risk for CS was identified.

Conclusions:

• CS incidence is lower than previously reported when not isolating high-risk fractures.
• Male sex, younger age, smoking, and Medicaid enrollment are independent risk factors for CS.
• CS is linked to increased long-term mortality, but not heritable.
