Randomized Controlled Trial Multicenter Study Comparative Study
Qigong and exercise therapy in patients with long-term neck pain: a prospective randomized trial.
A randomized, controlled, multicenter trial: 1-year follow-up. ⋯ These results indicate that treatments including supervised qigong or exercise therapy resulting in reduced pain and disability can be recommended for persons with long-term nonspecific neck pain.

Randomized Controlled Trial
Circumferential fusion is dominant over posterolateral fusion in a long-term perspective: cost-utility evaluation of a randomized controlled trial in severe, chronic low back pain.
Cost-utility evaluation of a randomized, controlled trial with a 4- to 8-year follow-up. ⋯ Circumferential fusion is dominant over instrumented posterolateral fusion, that is, both being significantly cheaper and significantly better in a long-term, societal perspective.

Randomized Controlled Trial
Effect of low-dose ketamine on voltage requirement for transcranial electrical motor evoked potentials in children.
Randomized controlled trial. OBJECTIVE.: To determine the effect of low-dose ketamine on the voltage needed to elicit maximal amplitude of the motor-evoked response to transcranial electrical stimulation during propofol/remifentanil anesthesia in children undergoing scoliosis surgery. ⋯ Addition of low-dose ketamine to propofol/remifentanil anesthesia does not significantly reduce the voltage needed to elicit maximum amplitude of the motor-evoked response to transcranial electrical stimulation.

Observational cohort study. ⋯ Stable vertebral fractures in childhood with no neurologic deficits at injury do not render more degenerative changes than can be expected according to age, but they are associated with more Schmorl's nodes at adjacent disc levels.

Case Reports
Brachial neuritis: an under-recognized cause of upper extremity paresis after cervical decompression surgery.
Case series. ⋯ Brachial neuritis appears to be an under-recognized cause of delayed-onset shoulder pain associated with upper extremity weakness that develops as a consequence of the stress of surgery rather than as a complication of surgical technique.
