Abstract

BACKGROUND

Decompressing an acute lower extremity compartment syndrome salvages muscle and nerve and preserves limb function. However, reperfusion of ischemic tissue causes a systemic insult that can be life threatening. Hence, the management of missed acute lower limb compartment syndrome remains controversial. The aim of this study was to evaluate the literature and, together with our own experience from a Level 1 trauma center, clarify the management of missed compartment syndrome in the physiologically stable patient.

METHODS

Pubmed, EMBASE, MEDLINE, the Cochrane database of systematic reviews and the Cochrane central register of controlled trials were searched. Studies were evaluated using the GRADE methodology. In addition, our trauma database was searched (2005 to May 2015) for additional cases, and a multidisciplinary case note review was conducted for all cases identified. This study was registered prospectively on the PROSPERO database (CRD42015026098).

RESULTS

Our systematic review yielded 9 studies, including one case-controlled study, 3 case series, and 5 case reports with a total of 57 patients and 64 limbs. Overall, study quality was “very low” with the exception of the case-controlled study, which was “low.” Delayed compartment decompression (6–120 hours) resulted in amputation rates of 5 of 24, 8 of 19, 4 of 5, and 2 of 3 limbs. Two patients died of complications associated with late compartment decompression. One compartment syndrome of the buttock was managed nonoperatively. Most surviving limbs exhibited functional deficits.

RESULTS

Additionally, our experience comprised 10 cases. Of the six who underwent compartment decompression, the burden of subsequent morbidity included three amputations (one above knee), two complete foot drops, and one episode of severe sepsis. As this experience mirrored the poor outcomes reported in the literature, we managed the four most recent cases nonoperatively. All remain ambulant with incomplete foot drops or limb weakness.

CONCLUSION

Surgical decompression of missed acute lower limb compartment syndrome yields an early physiological insult and a high late-amputation rate. Managing selected cases nonoperatively may result in less early morbidity and yield superior long-term results, but the evidence remains sparse and of poor quality.

LEVEL OF EVIDENCE

Systematic review, level III.
