    Citation Excerpt :

    The second patient had an intracapsular condylar fracture and developed myofascial pain dysfunction. The authors theorized that these and several other airbag-related temporomandibular joint injuries occur as a result of complex summation of forces generated by the inertia of the occupant traveling in a forward direction at impact, as well as by forces oriented in rearward and upward directions by the deploying airbag as it makes contact with the victim's mandible.1 Garcia19 suggests that temporomandibular joint injuries may occur either through posterior displacement of the condyles with anterior displacement of the menisci and compression of retrodiscal tissues in a closed or nearly closed mandible or, alternatively, via airbag impact with an extended mandible adding to the mandibular whiplash mechanism.

    The second patient had an intracapsular condylar fracture and subsequently developed myofascial pain dysfunction. The authors theorized that these and several other air bag-related TMJ injuries occurred as a result of a complex summation of forces generated by the inertia of the occupant traveling in a forward direction at vehicular impact, as well as by forces oriented in rearward and upward directions by the rapid deployment of the air bag as it makes contact with the victim's mandible.1 Garcia17 suggested that TMJ injuries may occur either through posterior displacement of the condyles with anterior displacement of the menisci and compression of retrodiskal tissues in a closed or nearly closed mandible or, alternatively, by air bag impact with an extended mandible, adding to the mandibular whiplash mechanism.
