Comparative Study
Reverse causality in the association between whiplash and symptoms of anxiety and depression: the HUNT study.
Longitudinal population-based cohort study. ⋯ This is the first published study with a prewhiplash prospective evaluation of psychological status. Our findings are in conflict with previous research suggesting whiplash to be the cause of associated psychological symptoms rather than their consequence. Self-reported whiplash injury was clinically relevant as it independently increased subsequent disability pension award. The strength of this effect, even in the absence of neck pain, suggests the ascertainment of this diagnostic label, or factors associated with this, are important predictors of disability.

Comparative Study
One, two-, and three-level instrumented posterolateral fusion of the lumbar spine with a local bone graft: a prospective study with a 2-year follow-up.
Prospective trial. ⋯ If one- and two-level posterolateral fusion were performed, the local bone graft technique provides a good and uniform bone union rate; however, for three-level fusion poor results were obtained because of an insufficient amount of local bone.

Case Reports
Percutaneous endoscopic lumbar discectomy via contralateral approach: a technical case report.
Technical case report. ⋯ When a conventional transforaminal PELD is difficult because of some anatomical reasons, PELD via a contralateral route could be a good alternative option in selected cases.

Case Reports
Administration of sodium ibandronate in the treatment of complicated giant cell tumor of the spine.
Case study. ⋯ These case studies demonstrate the potential promise of using sodium ibandronate in the treatment of primary and recurrent giant cell tumors of the spine. Furthermore, clinical evaluation should be performed in future studies.

Comparative Study
The effects of age, sex, ethnicity, and spinal level on the rate of intervertebral disc degeneration: a review of 1712 intervertebral discs.
A gross anatomic and magnetic resonance imaging study of intervertebral disc (IVD) degeneration in fresh cadaveric lumbar spines. ⋯ The relatively early degeneration at L5-S1 in all races and lower Thompson grade in donors of African ethnicity needs further investigation. Factors such as sagittal alignment, facet joint arthritis, and genetics potentially play a role in IVD degeneration.
