Chronic compartment syndrome also affects nonathletic subjects: A prospective study of 63 cases with exercise-induced lower leg pain

BACKGROUND: Chronic exertional compartment syndrome is most often reported in young and physically active people. PATIENTS AND METHODS: We studied 73 consecutive patients (mean age 39 (16-77) years, 45 women) with a history of exercise-induced pain and suspicion of chronic exertional compartment syndrome (CECS) of the lower leg--clinically, radiographically and with intramuscular pressure measurements. RESULTS: Intramuscular pressure increased with reproduction of symptoms and fulfilled the criteria for diagnosis of CECS in 36 patients (mean age 36 (16-65) years, 22 women), with engagement of 66 anterior, 2 lateral and 7 posterior muscle compartments in 72 legs. The patients with CECS of the lower leg were divided into 4 etiological groups: 18 with overuse, 10 with earlier trauma, 4 insulin-treated diabetics, and 4 others. Two-thirds of the patients had pain during walking. The outcome after fasciotomy was excellent or good in 41/57 of the legs. INTERPRETATION: CECS of the lower leg probably has a multifactorial etiology and is more common in sedentary individuals than has been recognized previously. Fasciotomy appears to be beneficial in these cases also.
