Abstract

Background

Patients with Chronic Exertional Compartment Syndrome (CECS) have pain during exercise that usually subsides at rest. Diagnosis is usually confirmed by measurement of intramuscular compartment pressure (IMCP) following exclusion of other possible causes. Management usually requires fasciotomy but reported outcomes vary widely. There is little evidence of the effectiveness of fasciotomy on IMCP. Testing is rarely repeated post-operatively and reported follow-up is poor. Improved diagnostic criteria based on pre-selection and IMCP levels during dynamic exercise testing have recently been reported.

Objectives

1. To compare IMCP in 3 groups, one with classical symptoms and no treatment and the other with symptoms of CECS who have been treated with fasciotomy and an asymptomatic control group. 2. Establish if differences in IMCP in these groups as a result of fasciotomy relate to functional and symptomatic improvement.

Methods

Twenty subjects with symptoms of CECS of the anterior compartment, 20 asymptomatic controls and 20 patients who had undergone fasciotomy for CECS were compared. All other possible diagnoses were excluded using rigorous inclusion criteria and MRI. Dynamic IMCP was measured using an electronic catheter wire before, during and after participants exercised on a treadmill during a standardised 15-minute exercise challenge. Statistical analysis included t-tests and ANOVA.

Results

Fasciotomy results in reduced IMCP at all time points during a standardised exercise protocol compared to pre-operative cases. In subjects responding to fasciotomy there is a significant reduction in IMCP below that of pre-operative groups (p˂0.001). Post-operative responders to fasciotomy have no significant differences in IMCP from asymptomatic controls (p=0.182).

Conclusion

Fasciotomy reduces IMCP in all patients. Larger studies are required to confirm that the reduction in IMCP accounts for differences in functional outcomes and pain reductions seen in post-operative patients with CECS.

Key Findings

1. Post-fasciotomy subjects demonstrate lower IMCP values compared to pre-operative symptomatic subjects at all time points. 2. Subjects who improve function and reduce pain after faSCiotomy demonstrate no Significant differences in dynamic IMCP measurement to normal controls.
