In the case of isolated sternal fractures, conservative treatment with analgesics is common, but pain can persist for more than 10 weeks, which can significantly interfere with daily life. Ultrasound-guided paravertebral nerve block is reported to be a successful means of pain control in patients with chest wall injury or rib fracture.

A 70-year-old female patient presented with anterior chest pain that had persisted for 2 weeks despite conservative treatment. Sagittal reconstruction chest computed tomography and sternum lateral oblique x-ray revealed an isolated sternal fracture. An ultrasound-guided bilateral paravertebral nerve block was performed for pain control. After performing the procedure twice at a 1-week interval, the patient reported complete pain alleviation, and no other problems were observed over the 3-month follow-up period.

Ultrasound-guided bilateral paravertebral nerve block can help patients with isolated sternal fractures to manage pain and return to normal activities sooner than with oral analgesics.
