Association between open tibia fractures and acute compartment syndrome: a retrospective cohort study
Abstract
BACKGROUND
studies on the association of open tibia fractures and acute compartment syndrome (ACS) show confusing results, with some papers highlighting a positive association, and others failing to do so. The aim of this study was to determine if an open tibia fracture is at increased risk of ACS occurrence, when compared to a closed fracture.
HYPOTHESIS
skin injury in the setting of an open tibia fracture does not prevent from ACS occurrence, because the energy transmitted to the limb during trauma may lead to soft tissue lesions, including skin lacerations and ACS.
PATIENTS AND METHODS
711 consecutive adult patients (mean age 44.6 years; 65.8% males) sustaining 725 tibia fractures between 01.01.2005 and 31.12.2009 were included in this retrospective study. The outcome measure was ACS. The following variables were assessed: soft tissue condition, age, sex, low- vs. high-energy injury, type of fracture, associated contiguous skeletal injury. A logistic regression model was used and adjustment was performed for age and sex.
RESULTS
ACS occurred in 10.4% of proximal intra-articular fractures, 10.4% of extra-articular fractures and 3.3% of distal intra-articular fractures, and in 8.7% of closed fractures, 7.8% of open Gustilo 1 fractures and 13.3% of open Gustilo 2 and 3 fractures. Open lesions were not associated with ACS when tibia fractures were considered as a whole. When stratifying by types of fractures, open Gustilo 2 and 3 lesions were associated with ACS in proximal…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 711 participants or records.
