A self-limiting injury that requires proper pain control

Isolated sternal fractures are typically self-limiting with a good prognosis.² These injuries are managed supportively with rest, ice, and analgesics¹; proper pain control is crucial to prevent respiratory compromise.⁸

Complete recovery for most patients occurs in 10 to 12 weeks.⁹ Recovery periods longer than 12 weeks are associated with nonisolated sternal fractures that are complicated by soft-tissue injury, injuries to the chest wall (such as sternoclavicular joint dislocation, usually from a fall on the shoulder), or fracture nonunion.^1,2,5

Although sternum fractures are rare in pediatric patients, twothirds of these fractures are associated with injuries to surrounding structures.

Anterior sternoclavicular joint dislocations and stable posterior dislocations are managed with closed reduction and immobilization in a figure-of-eight brace.¹ Operative management is reserved for patients with displaced fractures, sternal deformity, chest wall instability, respiratory insufficiency, uncontrolled pain, or fracture nonunion.^1,3,8

A return-to-play protocol can begin once the patient is asymptomatic.¹ The timeframe for a full return to play can vary from 6 weeks to 6 months, depending on the severity of the fracture.¹ This process is guided by how quickly the symptoms resolve and by radiographic stability.⁹

Our patient was followed every 3 to 4 weeks and started physical therapy 6 weeks after his injury occurred. He was held from play for 10 weeks and gradually returned to play; he returned to full-contact activity after tolerating a practice without pain.

THE TAKEAWAY

Children typically have greater chest wall elasticity, and thus, it is unusual for them to sustain a sternal fracture. Diagnosis in children is complicated by the presence of ossification centers for bone growth on imaging. In this case, the fracture was first noticed on ultrasound and confirmed with MRI. Since these fractures can be associated with damage to surrounding structures, additional injuries should be considered when evaluating a patient with a sternum fracture.
