Cervical dystonia following exposure to high-G forces.
Injuries to the cervical region have been associated with high-G loads sustained during air combat maneuvering (ACM) in high performance fighter aircraft. The spectrum of injuries ranges from mild neck pain to musculoskeletal strain, injury to the nerve roots or spinal cord, and fracture of the cervical spine. A 36-year-old fighter pilot with 2,800 h in tactical jet aircraft developed progressive cervical dystonia (spasmodic torticollis), following an ACM flight. The patient was successfully treated with local intramuscular injections of botulinum toxin into the affected cervical muscles, resulting in total relief of his spasmodic torticollis. The aeromedical considerations of this rare complication of exposure to G forces in high performance aircraft are discussed.
