[Biomechanical aspects of cervical trauma]

Area of Science:

• Biomechanics of traumatic injuries.
• Orthopedics and sports medicine.
• Forensic biomechanics.

Context:

• Clinical reports often lack precise biomechanical terminology, compromising injury assessments.
• Physicians may lack specialized training in injury biomechanics, relying on familiar clinical findings.
• Accurate documentation of injury mechanisms is vital for expert biomechanical opinion.

Purpose:

• To clarify the complex biomechanics of neck injuries.
• To differentiate between contact and non-contact injury mechanisms.
• To address the inaccuracies and limitations of the term "whiplash" in describing neck trauma.

Summary:

• Neck injuries result from indirect trauma, either head contact or non-head-contact mechanisms.
• Mechanisms include hyperflexion, hyperextension, and hypertranslation, with shearing forces at C1-C2.
• The term "whiplash" is misleading, incorrectly implying a whip-like motion and conflating mechanism with injury type.

Impact:

• Promotes accurate terminology in clinical reporting of neck injuries.
• Enhances understanding of injury mechanisms for better medical-legal evaluations.
• Aids clinicians in focusing on relevant findings by clarifying biomechanical principles.
