Development of adjacent segment degeneration following anterior cervical decompression and fusion (ACDF) is still controversial, as adjacent-level kinematics is poorly understood. This study reports preliminary data from a high-accuracy 3D analysis technique developed for in vivo cervical kinematics. ⋯ This study showed increased segmental motion in flexion/extension angular-ROM at one level adjacent to ACDF. However, increases in the rotational angular-ROM were not statistically significant when cranial/caudal adjacent levels were analyzed separately. This preliminary study highlighted the capabilities of a 3D-kinematic analysis method to detect subtle changes in kinematics and disc height at the adjacent levels to ACDF. Thus, reliable evidence related to ACDF's influence on adjacent-level cervical kinematics can be collected.

Randomized Controlled Trial Comparative Study
Knowledge transfer of spinal manipulation skills by student-teachers: a randomised controlled trial.
To assess the use of peer-assisted learning (PAL) of complex manipulative motor skills with respect to gender in medical students. ⋯ The peer-assisted learning system does not seem to be generally qualified to transfer such complex spatiotemporal demands as spinal manipulative procedures.

Comparative Study
Continuing conservative care versus crossover to radiofrequency kyphoplasty: a comparative effectiveness study on the treatment of vertebral body fractures.
There is controversy about how to treat vertebral fractures. Conservative care is the default approach. Radiofrequency kyphoplasty uses ultrahigh viscosity cement to restore spinal posture and stabilize the fracture. The aims of this study were to compare radiofrequency kyphoplasty to conservative care and assess the usual algorithm of starting all patients on conservative care for 6 weeks before offering surgery. ⋯ For the vast majority of patients with a VAS ≥5, conservative care did not provide meaningful clinical improvement. In contrast, nearly all patients who underwent radiofrequency kyphoplasty had rapid substantial improvement. Surgery was clearly much more effective than conservative care and should be offered to patients much sooner.
