Factors associated with myonecrosis at time of fasciotomy in acute leg compartment syndrome

INTRODUCTION

The objective of this study is to determine factors associated with myonecrosis at the time of fasciotomy in patients with acute leg compartment syndrome.

METHODS

A retrospective cohort study was conducted of 546 patients with acute leg compartment syndrome treated with fasciotomies from January 2000 to June 2015 at two tertiary trauma centers. The main outcome measurement was clinical myonecrosis diagnosed by the treating surgeon at the time of fasciotomy.

RESULTS

Eighty-two patients (15.0%) with acute leg compartment syndrome had myonecrosis at time of fasciotomy. Multivariable logistic regression analyses showed that younger age (p = 0.004) and diabetes mellitus (p < 0.001) were associated with myonecrosis at time of fasciotomy in acute leg compartment syndrome. Serum creatine kinase at presentation greater than 2405 U/L was found to be associated with myonecrosis at time of fasciotomy in post hoc analysis (p < 0.001).

CONCLUSIONS

Myonecrosis is associated with patient-related factors. Younger age by 10 years is associated with a 1.3 times increase and diabetes mellitus with a 3-time increase in the odds of myonecrosis. Serum creatine kinase at presentation greater than 2405 U/L denotes an almost 3 times increase in odds of myonecrosis and may be useful for preoperative counseling.
