Cervical injuries--perils of the swimmer's view: case report.

A subluxation of an unstable cervical spine injury occurring during swimmer's positioning is described. Based on this experience, it is recommended that the initial radiographs be obtained and reviewed without traction or swimmer's positioning. With clinical or radiographic evidence of cervical injury, bilateral oblique views, plain lateral tomography, or computerized axial tomography may be required to evaluate the C7-T1 junction.
