Acute Hematogenous Osteomyelitis Resulting in Atraumatic Pediatric Forearm Compartment Syndrome

Abstract

Acute hematogenous osteomyelitis is well described after minor trauma in the pediatric population, with an incidence of 1 to 13 cases per 100,000 individuals. Compartment syndrome (CS) in children is a rare, but potentially devastating disease, classified as "cannot miss diagnosis." Compared with adults, CS may exhibit a variable presentation with a wide range of symptoms in children, often leading to delayed diagnosis. Expeditious diagnosis and treatment of CS is paramount in minimizing adverse sequelae and maximizing potential functional outcome, regardless of etiology. Here, we present a rare case of atraumatic CS resulting from ruptured subperiosteal abscess secondary to acute hematogenous osteomyelitis in a pediatric male patient with 2 weeks of forearm pain and evolving neurologic deficits with initial delay in presentation to our facility. The ramifications of delayed diagnosis or misdiagnosis of CS emphasize the importance of a high index of suspicion despite atypical presentations in the pediatric patient.
