Due to the vehicle characteristics neck injuries are common in motorcycle and moped users involved in traffic accidents. We are reporting on neck injuries amongst 502 fatalities of drivers and passengers of motorcycles and mopeds, and cyclists. Cervical spine injuries were found in 124 cases (24.7%). Cervical spine injury was statistically significantly more frequently in passengers (61.9%) compared to the drivers (20.7%) of motorcycle and moped (chi2 = 13.384; p < 0.01), the lesions are usually localized in the upper cervical spine (52.4%), the most frequently at atlantoocciptal region (F = 25.835; p); these injuries were most frequently caused by frontal (31.45%) or rear (50.81%) axial collisions. Almost all cases of cervical spine injuries were present without apparent external injuries; they were associated with lesions of neck muscles, blood vessels and/or neck organs, and in 79 cases (63.7%) there was a lesion of the cervical spinal cord. The research results indicate a large incidence of neck injuries in traffic accidents especially in motorcycle, moped and bicycle axial collision with the possible absence of external injuries, which may represent a clinical and forensic problem.
