Interpreting elbow radiographs in children

Area of Science:

• Pediatric Orthopedics
• Radiology
• Pediatric Trauma

Background:

• Elbow fractures in children present diagnostic challenges due to evolving anatomy and multiple ossification centers.
• Radiographic interpretation requires understanding normal developmental variations to avoid misdiagnosis.

Purpose of the Study:

• To review the radiographic diagnosis of elbow fractures in pediatric patients.
• To highlight key imaging findings and assessment methods for accurate diagnosis.

Main Methods:

• Review of anteroposterior (AP) and lateral radiographs, with consideration for oblique views.
• Evaluation of anterior and posterior fat pad signs for joint effusion.
• Assessment of joint alignment using the intersection of anterior humeral and central radial lines.

Main Results:

• Multiple ossification centers can mimic fractures, complicating diagnosis.
• Anterior and posterior fat pad signs suggest significant trauma and joint effusion.
• Fractures with displacement < 2 mm are generally considered stable.

Conclusions:

• Accurate diagnosis relies on understanding pediatric elbow anatomy and development.
• Specific radiographic signs (fat pads, alignment lines) are crucial for identifying elbow injuries.
• Conservative management is appropriate for stable pediatric elbow fractures with minimal displacement.
