Acute traumatic thoracolumbar paraspinal compartment syndrome: case report.

Although compartment syndrome can occur in any compartment in the body, it rarely occurs in the paraspinal musculature and has therefore only been reported in a few case reports. Despite its rare occurrence, acute paraspinal compartment syndrome has been shown to occur secondary to reperfusion injury and traumatic and atraumatic causes. Diagnosis can be based on clinical examination findings, MRI or CT studies, or through direct measurement of intramuscular pressures. Conservative management should only be used in the setting of chronic presentation. Operative decompression via fasciotomy in cases of acute presentation may improve the patient's symptoms and outcomes. When treating acute paraspinal compartment syndrome via surgical decompression, an important aspect is the anatomical consideration. Although grouped under one name, each paraspinal muscle is enclosed within its own fascial compartment, all of which must be addressed to achieve an adequate decompression. The authors present the case of a 43-year-old female patient who presented to the emergency department with increasing low-back and flank pain after a fall. Associated sensory deficits in a cutaneous distribution combined with imaging and clinical findings contributed to the diagnosis of acute traumatic paraspinal compartment syndrome. The authors discuss this case and describe their surgical technique for managing acute paraspinal compartment syndrome.
