What is biomeCrawford,_Dzingai_200_m_Berlin_2009chanics? It is a scientific discipline which applies principles studied in mechanics to the understanding of living organisms. So, what does this mean to the LNC?

As a LNC we are challenged to determine if a claimant’s reported injury or injuries can be the result of the mechanism of injury he/she has reported. As a new LNC I have learned this is easier said than done. I am thankful for the LNC who has helped me edit the reports I have completed, she told me to study biomechanics. Studying biomechanics has helped me to better understand the relationship between the M.O.I and the claimant’s reported injuries much better.

For example disk herniations are uncommon in front and side impact cars crashes that are severe enough to cause other serious spinal injuries. In laboratory testing, pure compression, torsion and flexion do not result in disk herniation. Only a combination of lateral bending, hyperflexion, and severe compression can cause a herniation. This is usually the result of heavy lifting, but rarely occurs anywhere in the spine during automobile accidents.

In rear end collisions the neck is most likely to sustain injury and the thoracic and lumbar spine is less likely due to protection by the seat and restraints. Proper placement of the head rest would be an important piece of information to obtain because it can reduce the chance of whiplash injury to the neck.

So a study in biomechanics and how it relates to the body when an injury occurs can be most beneficial to a LNC who is trying to see if the claimant’s reported injury or injuries are a result of the reported M.O.I. or related to another incident.
