BACKGROUND: There has been an increase in minimally invasive surgery for chronic @entity2054 (CECS), despite the potential for incomplete compartment release and @entity130 . To our knowledge, no study has examined the effect of the length of fascial release on compartment pressures. PURPOSE/HYPOTHESIS: The purpose was to explain the high failure rate seen in fascial release for CECS by evaluating the effect of @entity3656 on intracompartmental pressures. We hypothesized that complete fascial release would need to be performed to return pressures to baseline levels. STUDY DESIGN: Controlled laboratory study. METHODS: Five male @entity1707 (10 lower extremities) were anesthetized. A slit catheter, connected to a pressure monitor, was inserted into the anterior compartment and a solution containing 5% @entity1707 albumin was injected into the compartment until the compartment pressure was >25 mm Hg for 10 minutes. Pressures were measured at rest, after the injection, and after each 10% @entity16877 . RESULTS: The mean resting intracompartmental pressure was 3.2 mm Hg (range, 0-6 mm Hg), which increased after the injection to a mean of 37 mm Hg (range, 26-67 mm Hg). After complete fasciotomy, the mean pressure was 1.1 mm Hg (range, 0-4 mm Hg). There was a strong negative correlation (r=-0.693) between @entity3656 and intracompartmental pressure. In 90% of the specimens, the pressures were <15 mm Hg after 80% fascial release, and after 90% release, all pressures were  <=8 mm Hg. CONCLUSION: This study demonstrates a strong correlation between @entity3656 and a reduction in intracompartmental pressures in a @entity1707 model. Our study suggests that 90% fascial release may represent a possible watershed zone, returning the intracompartmental pressure to a value at or near baseline values. CLINICAL RELEVANCE: The results suggest that even in cases with near complete fascial release, intracompartmental pressures may decrease enough to provide symptomatic relief and avoid possible @entity130 associated with percutaneous release. It is unknown whether the @entity1707 model may adequately translate to the clinical setting; thus, recommendations should be taken with caution, and future studies should be performed to examine the correlation in a @entity1 model.
