Sospette fratture costali: quale imaging?
Rib fracture is the most common thoracic injury: 10%
of all traumatic injuries
ACR, Appropriateness Criteria - 2014
Almost 40% of patients who sustain severe non penetrating
chest trauma
Bansidhar BJ, Am Surg. 2002 Alkadhi H, J Comput Assist Tomogr. 2004
Isolated rib fractures have a low morbidity and mortality
Bansidhar BJ, Am Surg. 2002 Alkadhi H, J Comput Assist Tomogr. 2004
The diagnosis of associated complications may have a more
significant clinical impact

Several studies have investigated the role of US in the detection of rib fractures
CHEST ULTRASOUND

The ultrasound imaging is not complicated and can also be
performed by trained clinicians

Prospective study: 50 patients with clinical suspicion of rib fracture

Detection of chest wall fractures: sensitivities of US (80.3%), clinical acumen (26.0%), chest radiography (23.7%)
Rainer, J Trauma. 2004
Radiography may miss 50% of rib fractures, especially those occurring in
costal cartilages and non dislocated fract.
M. E. Hurley. Injury 2004
Ultrasound also detects costal cartilage fractures and costo-chondral junction fractures
better than radiography

further studies with a well-established gold standard should be completed before ultrasonography is used routinely
Nella diagnosi delle fratture costali gli US hanno un ruolo di rilievo,
specie nei bambini e nelle gravide
La diagnosi è di scarso impatto ai fini della gestione clinica e del trattamento
E’ più importante diagnosticare tempestivamente le complicanze

Injury, Int. J. Care Injured (2004)
A prospective study. Patients presenting with a high clinical suspicion of rib fracture(s) to the Accident and Emergency Department were referred for radiological work-up with a PA chest radiograph, an oblique rib view and a chest ultrasound
US is marginally superior to plain film and especially oblique rib views for rib fracture detection and may be helpful in diagnosing rib fractures not visualized on conventional radiography, if clinically indicated.
