BackgroundThe objective of this study was to identify demographic, injury-related, and treatment-related characteristics of patients who underwent decompressive fasciotomies for acute thigh compartment syndrome. MethodsA cohort of 38 adult patients with acute thigh compartment syndrome treated with fasciotomy at two tertiary care referral centers over a 10-year time period from January 1, 2006 to June 30, 2015 were retrospectively identified. We searched the electronic medical record for patient-related variables (e.g., age, sex, race, smoking status, diabetes mellitus), injury-related variables (e.g., mechanism of injury, associated fractures, other traumatic injuries), treatment-related variables (e.g., delay to treatment, compartments released, number of debridements, use of split-thickness grafts), and outcomes (e.g., amputation, death, sensory/motor impairments at final follow-up). ResultsThe mean age of our cohort was 47 years, and 35 patients (92%) were male. There were various mechanisms of injury, but the most common mechanisms were spontaneous hematoma (21%), followed by motor vehicle accidents (16%). Associated leg fractures were present in 15 (39%) patients. Delay between time of injury and fasciotomy was greater than 24 hours in 27 patients (71%), 12 to 24 hours in 6 patients (16%), and less than 6 hours in 3 patients (8%). The most frequently released compartment was the anterior compartment only (68%), followed by both the anterior and posterior compartments (16%) and the posterior compartment only (11%). Six patients (16%) had motor impairment, and 2 patients (5%) had sensory impairment at final follow-up. There were 2 deaths (5%) recorded in the hospital course for this cohort, none of which were directly related to compartment syndrome of the thigh. ConclusionDelays to fasciotomy are frequent in the treatment of acute thigh compartment syndrome. The demographics of acute thigh compartment syndrome demonstrate a strong male predominance. Treating providers should recognize spontaneous hematoma and motor vehicle accidents as the most common causes of acute thigh compartment syndrome.
