Rear End MVA: Head Position and Neck Injury

Rear end MVA

At the Centeno-Schultz Clinic we acknowledge the potential impact of motor vehicle accidents on a patient’s well-being.

Injuries to ligaments, facet joints, muscles, intervertebraldisc and nerves can occur.acceleration deceleration

Rear end motor vehicle accidents can cause an acceleration deceleration injury to the cervical spine.

Does head position at time of impact in a rear end MVA matter?  Does it led to injury of specific areas?

Panjabi examined these concerns in a 2006 study.  He concluded that head-turned rear impact caused significantly greater injury at C0-C1 and C5-C6 facet joint, as compared to head-forward rear and frontal impacts which resulted in multiplanar injuries at C5-C6 and C7-T1.

This is significant as the pain referral patterns are different as previously discussed.

The C0-C1 facet refers to the suboccipital area whereas the C5/6 and C7/1 facets refer to the periscapular area.

Knowing the importance of head position in a rear end MVA is critical to understanding what areas are at greatest risk for injury and how best to treat them.  This is standard of care at the Centeno-Schultz Clinic.
