Acute compartment syndrome of the deltoid: a case report and systematic review of the literature.

Background: Deltoid compartment syndrome is a rare entity. The purpose of this study was to report a recent case and perform a systematic literature review.

Methods: Patient data were gathered from chart review and clinical encounters. For the review, the MEDLINE, Embase, and Ovid databases were queried for deltoid compartment syndrome cases. Seventeen articles reporting on 18 patients with deltoid compartment syndrome were included.

Results: Including our patient, 9 of 19 patients (47.4%) presented with compartment syndrome limited to the deltoid. Most patients presented with additional affected compartments, most commonly in the ipsilateral arm (7 of 19, 37%). Isolated deltoid involvement often resulted from iatrogenic injury; of 10 iatrogenic reports, 8 involved only the deltoid. Of 19 cases, 5 (26%) occurred in powerlifters, climbers, or anabolic steroid or testosterone injectors. In 13 of 19 cases (68%), the patients were men aged 18-36 years, and only 1 female case (5%) was reported. Prolonged recumbence owing to substance abuse was documented in 6 of 19 cases (32%).

Conclusion: Deltoid compartment syndrome is rare, with only 19 reported cases, including our patient. Men are more commonly affected, and isolated deltoid compartment syndrome occurs in about 50% of reported cases. More than half of cases are iatrogenic, secondary to prolonged lateral decubitus positioning, injections, and surgical interventions about the shoulder. Prolonged recumbence from intoxication is also a common etiology. Providers should be aware of and recognize deltoid compartment syndrome to facilitate urgent surgical management.
