Auto Accidents and Whiplash Injury
A recent abstract discussing The Whiplash and TMJ Dysfunction. The Spine Research Institute of San Diego.
TM injuries occur during motor vehicle accidents. This abstracts several articles to describe the forces involved to the TM joint during rear-end motor vehicle accidents. It also challenges the article by Howard et. al, that used a poorly designed model-without considering other works contrary to their methodology-which oversimplified the working of the cervical spine.
There is good supporting evidence that the TMJ receives injury during the initial acceleration phase during whiplash injuries. Stretching and tearing of the posterior attachments, as well as the discal attachments of the medial and lateral parts of the condyle, may occur. In the second phase (the deceleration phase), the head and neck are snapped forward into flexion. The exact sequela of events in this phase are yet undetermined. Enough evidence is presently available to refute Howard's criticism of TM whiplash injuries. Enough evidence also exists to substantiate that major injuries occur to the TM joint apparatus during whiplash related injuries.
The TM joint and related structure can receive sumstantial injuries during cervical whiplash related accidents.
If you suspect you may or may have had a whiplash injury due to an auto accident or experience headaches as a result of an auto accident, please see your Neuromuscular/TMD Dentist.
