[Limb fractures: ultrasound imaging features]

Area of Science:

• Orthopedics
• Radiology
• Medical Imaging

Background:

• Radiographs are standard for limb fracture evaluation.
• Ultrasound (US) offers a non-irradiating alternative and complementary imaging modality.
• US can detect fractures not visible on radiographs.

Purpose of the Study:

• To review the direct and indirect US findings of limb fractures.
• To correlate US findings with radiographic evidence.
• To enhance the understanding of US in fracture diagnosis.

Main Methods:

• Review of direct and indirect US findings in limb fractures.
• Correlation of US findings with radiographic images.
• Discussion of specific US features indicative of fractures.

Main Results:

• Direct US findings include cortical discontinuity and irregularity.
• Indirect US findings include subperiosteal hematoma (suggesting cortical fractures) and juxtaphyseal hematoma (suggesting physeal fractures).
• US can identify fractures with or without radiographic abnormalities.

Conclusions:

• Ultrasound is a valuable tool for evaluating limb fractures.
• Understanding US features is crucial for accurate fracture diagnosis.
• US complements radiography in fracture assessment.
