Expert debate and synthesis of research to inform future management approaches for acute whiplash disorders. ⋯ The burden of whiplash injuries, the high rate of transition to chronicity, and evidence of limited effects of current management on transition rates demand new directions in evaluation and management. Several directions have been proposed for future research, which reflect the potential multifaceted dimensions of an acute whiplash disorder.

An anatomic study of anterior cervical dissection of 11 embalmed cadavers and measurement of structures relative to cervical spine. ⋯ On the basis this study, spine surgeons can have enhanced knowledge of high anterior cervical anatomy. The neurovascular structures in this study did not demonstrate side-to-side anatomic variation; therefore, patient pathology and surgeon preference should dictate the operative side.

Randomized Controlled Trial Multicenter Study
Lumbar disc arthroplasty with Maverick disc versus stand-alone interbody fusion: a prospective, randomized, controlled, multicenter investigational device exemption trial.
Randomized, controlled, multicenter, investigational device exemption trial. ⋯ The investigational group consistently demonstrated statistical superiority versus fusion on key clinical outcomes including improved physical function, reduced pain, and earlier return to work.

Randomized Controlled Trial Comparative Study
Segmental contribution toward total cervical range of motion: a comparison of cervical disc arthroplasty and fusion.
Prospective radiographic evaluation of patients that underwent cervical total disc replacement (TDR-C) or anterior cervical discectomy and fusion (ACDF) for one-level cervical disc disease. ⋯ Compensation for the loss of motion at the operative level in ACDF is seen throughout the unfused cervical spine. Cervical disc arthroplasty, however, increases total cervical ROM compared with ACDF and maintains a physiologic distribution of ROM throughout the cervical spine at 2 years, potentially lowering the risk for adjacent segment breakdown.
