Cervical intervertebral disc protrusion in an RAAF F-111C pilot: a case report.

This case report describes a serious cervical spine injury occurring in an F-111 pilot of the RAAF. The pilot developed a significant cervical intervertebral disc protrusion with severe, progressive neurological signs and symptoms in his right arm for a period of 4 mo. Multiple investigations including MRI and myelography established the site of the lesion as C6/7. He eventually responded to bed rest and made a complete recovery. The aeromedical disposition of this aviator and the roles of different treatment modalities in the aviation environment are discussed. The need for more research into +Gz-related neck injuries and the requirement for preventive strategies to protect the cervical spines of high performance pilots are also highlighted.
