Comparative Study
Auditory startle alters the response of human subjects exposed to a single whiplash-like perturbation.
Human volunteers were exposed to a single whiplash-like perturbation. ⋯ An acoustic startle alters the neck muscle and kinematic responses and may be as important as gender in the genesis of whiplash injury.

Comparative Study
Radiographic analysis of intervertebral separation with a 0 degrees and 30 degrees rope angle using the Saunders cervical traction device.
Radiographic analysis of cervical intervertebral separation, (IVS) while using the Saunders Cervical Traction Device (SCTD) (Chattanooga Corp., Chattanooga, TN) on a healthy population. ⋯ The research findings may have treatment implications when applying cervical traction with the SCTD. Further research using subjects with cervical nerve root compression will need to be conducted to substantiate clinical outcomes.

Comparative Study
Radiographic assessment of segmental motion at the atlantoaxial junction in the Klippel-Feil patient.
A retrospective review of 33 consecutive Klippel-Feil syndrome (KFS) patients at a single institution. ⋯ Hypermobility of the atlantoaxial junction, as indicated by increased AADI on flexion-extension radiographs, is not necessarily associated with an increased risk for the development of symptoms or neurologic signs in the KFS patient. Occipitalization plays an integral role in the degree of motion at the atlantoaxial region. Greatest AADI values were in patients with occipitalization and a fused C2-C3 segment. The presence of symptoms was not related to the degree of AADI change. Evaluation of the PADI provides additional information for identifying patients at risk for developing symptoms. Nonetheless, KFS patients remain largely asymptomatic.

A retrospective chart and radiographic review of patients with a Fontan physiology who underwent surgical correction of their scoliosis. ⋯ Operative treatment of scoliosis in these patients may be successful; however, complications are frequent and significant.
