Fasciotomy and Occupational Separation among US Service Members with Lower Extremity Chronic Exertional Compartment Syndrome

Abstract

Purpose: Lower extremity chronic exertional compartment syndrome (LE-CECS) can limit rigorous physical activity, particularly in the US military, and fasciotomy is a potential treatment. Associations between LE-CECS, fasciotomy, and occupational outcomes appear understudied. We studied active-duty US service members to identify whether LE-CECS diagnoses and fasciotomy for LE-CECS predict military service separation.

Methods: We conducted a retrospective cohort study of 1,103,417 individuals who entered service during 2011 to 2017. Distributions of separation statuses and independent variables were tabulated, and sex-specific multivariable regression models were computed for separation outcomes.

Results: LE-CECS was associated with a 474% medical service separation risk in men (95% confidence interval (CI) for adjusted risk ratio: 5.21 to 6.33) and a 282% increase in women (CI: 2.99 to 4.88). Among 1947 patients with LE-CECS, men saw a 57% nonmedical separation risk increase (CI: 1.27 to 1.93) and women had a 119% increase (CI: 1.10 to 4.35) when anterior and/or lateral compartment procedures occurred. Men with LE-CECS and any posterior procedures saw a 47% nonmedical separation risk increase (CI: 1.17 to 1.86). Men with anterior and/or lateral procedures and any posterior procedures experienced 36% (CI: 1.09 to 1.71) and 78% (CI: 1.40 to 2.26) medical separation risk increases, respectively. No statistically significant risk increases for the outcomes were otherwise seen for women.

Conclusions: LE-CECS was associated with increased military service discharge risks. Among the affected patients, positive effects on career longevity were not seen in association with fasciotomy. However, fasciotomy could simply serve as a marker of the most refractory cases that are least likely to continue service. More study is needed to clarify causal pathways and identify patients who may derive career benefits from surgical treatment.
