We retrospectively reviewed surgical results of posterolateral transpedicular partial corpectomy without anterior vertebral reconstruction in 23 consecutive patients with symptomatic metastatic spinal cord compression at thoracic spine. ⋯ The results of this study suggest that the stability of implants can be maintained up to 55.8 months without anterior vertebral reconstruction in thoracic spine.

A prospective study involving 56 patients with cervical spondylotic myelopathy (CSM) was conducted. ⋯ Outcomes of mild forms of CSM during nonsurgical treatment were generally good as shown by average JOA scores. The only prognostic factor for mild forms of CSM was circumferential spinal cord compression in the maximum compression segment on axial MRI. Surgical treatment can be considered for patients with this prognostic factor.

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.
