An injury to the neck region caused by forcible flexion and, for example after a car accident involving sudden deceleration. The injury usually affects the ligaments, spinal joints and soft tissues of the neck. Subluxation (partial dislocation) of a cervical joint sometimes occurs and cervical vertebra may occasionally be fractured if the forces are severe. Pain and stiffness of the neck result. The patient usually recovers fully but may take several weeks, months or, in the worst cases, years, to do so. Unfortunately, experience in the UK has been that amongst the many genuine cases there are many fraudulent claims for this injury by people seeking compensation. Treatment includes immobilisation of the neck in a collar, and analgesic and muscle-relaxing drugs. PHYSIOTHERAPY may be necessary.
