Ultrasound as an adjunct to radiography in minor musculoskeletal pediatric trauma

الملخص EN

Purpose : To assess the value of ultrasound as an adjunct to radiography in minor musculoskeletal pediatric trauma.

Methods : Fifty children with 53 suspected fractures were referred for upper and / or lower limbs X-rays, followed by ultrasound.

On radiography, we noted presence of fracture, of soft tissue thickening, or absence of any lesion.

On ultrasound, we noted presence of fracture, of soft tissue lesion, or absence of lesions.

Results : A fracture was seen on both examinations in 25 patients with 28 fractures.

In 4 patients where only soft tissue thickening was seen on radiography, ultrasound showed fracture in 1 patient, hematoma in 1 patient and was normal in 2 patients.

In another patient with a doubtful diagnosis of fracture on radiography, ultrasound was normal.

In 20 patients with normal X-rays, ultrasound showed fracture in 6 patients, hematoma in 7 patients and was normal in 7 patients.

Conclusion : Ultrasound was helpful as an adjunct to radiography, it yielded additional bone (7 / 50 patients) and soft tissue (8 / 50 patients) diagnostic information in 30 % of patients.

However, ultrasound remains operator-dependent and can be used only in particular circumstances, especially in children with normal X-rays and a high index of clinical suspicion for an occult or subradiological fracture.
