Randomized Controlled Trial
Anterior cervical fusion with tantalum implant: a prospective randomized controlled study.
A prospective randomized controlled study was carried out. ⋯ The efficacy to achieve fusion after 1-level anterior cervical discectomy, with a good radiologic and clinical outcome, using tantalum implant is equivalent to that of autologous graft and anterior plate, being safer as avoids donor-site graft harvesting and plating complications.

Randomized Controlled Trial
Effect of intervertebral disc height on postoperative motion and outcomes after ProDisc-L lumbar disc replacement.
Retrospective study of patients enrolled in prospective randomized Food and Drug Administration trial. ⋯ Patients with greater disc collapse benefit more in ROM from a total disc replacement. The optimal range to maximize ROM for postoperative anterior disc height is 16 mm to 18 mm. This optimal range did not translate into better clinical outcome at 2 years follow-up.

A cross-sectional survey among health professionals working in a Kuwait hospital. ⋯ No causal relationships can be inferred using these cross-sectional data. However, results suggest that direct patient contact that includes lifting and/or transferring patients may be an important risk factor. Further research is warranted to evaluate effectiveness of back education and prevention programs among hospital staff in Kuwait.

A prospective cohort study in adolescents. ⋯ Regular smoking in adolescence was associated with LBP in young adults. Pack-years of smoking showed an exposure-response relationship among girls.

A retrospective study. ⋯ The impact of ASD on clinical outcome after fusion showed a significant correlation, especially with the ASD after multiple-segments fusion. Careful attention is needed in multiple-segments fusion such as degenerative lumbar deformity.
