Pediatric cervical spine: normal anatomy, variants, and trauma

Area of Science:

• Pediatric Radiology
• Orthopedic Imaging
• Pediatric Traumatology

Background:

• Emergency radiologic evaluation of pediatric cervical spine injuries presents challenges due to normal variants and unique pediatric anatomy.
• Pediatric cervical spine injuries predominantly affect the upper cervical region due to distinct biomechanical factors.
• Accurate interpretation necessitates knowledge of normal embryologic development and anatomical variations.

Purpose of the Study:

• To highlight the complexities in interpreting pediatric cervical spine imaging.
• To emphasize the importance of understanding normal pediatric cervical spine anatomy and variants.
• To guide radiologists in differentiating normal findings from traumatic injuries.

Main Methods:

• Review of normal pediatric cervical spine embryology and anatomy.
• Identification and description of common normal variants (e.g., pseudosubluxation, widened predental space).
• Discussion of injury patterns unique to the pediatric cervical spine and relevant imaging modalities.

Main Results:

• Synchondroses can be mistaken for fractures without knowledge of normal development.
• Anatomical variants like pseudosubluxation and pseudo-Jefferson fractures are common and require recognition.
• Upper cervical spine injuries are prevalent in children due to specific biomechanics.

Conclusions:

• Familiarity with pediatric cervical spine embryology, anatomy, and variants is crucial for accurate radiologic interpretation.
• Distinguishing normal findings from injuries prevents misdiagnosis in pediatric trauma.
• Understanding injury mechanisms and imaging modalities improves diagnostic confidence.
