Aims Intermittent claudication is common in diabetes mellitus. However, a proportion of patients with diabetes have symptoms of claudication without signs of vascular disease and these patients were evaluated for chronic exertional compartment syndrome.
Methods Forty-two patients with diabetes (10 men, 32 women), earlier investigated at diabetic clinics because of claudication with no explanation for the symptoms, were examined. Their median age was 48 years (18–72 years) and the median duration of diabetes was 29 years (1–45 years). Thirty-one patients had Type 1 diabetes, 11 had Type 2 diabetes and 29 had diabetic complications. All were investigated clinically, with radiography, bone scan and intramuscular pressure measurements.
Results Thirty-eight of 42 patients with diabetes were diagnosed with chronic exertional compartment syndrome of the lower leg and 32 were treated surgically. Thirty-one patients were operated with fasciotomy of the anterior compartment and 18 also with fasciotomy of the posterior compartment. Additionally, one patient had only fasciotomy of the posterior compartment. Fourteen of 32 surgically treated patients (27 legs) were followed for more than 2 years and rated the post-operative outcome as excellent or good in 21 of the treated legs. The walking distance before lower leg pain increased in all but one patient and seven patients reported unrestricted walking ability.
Conclusions Chronic exertional compartment syndrome should be considered as a differential diagnoses in patients with diabetes and exercise-related lower leg pain. The results after surgery are encouraging and the increased walking ability is beneficial in the treatment of diabetes.
