The aim of this study is to investigate changes in lumbar motor neurons induced by mechanical nerve root compression using an in vivo model. This study is to investigate the changes of lumbar motor neuron induced by mechanical nerve root compression using in vivo model. ⋯ It is important to be aware that, in patients with nerve root compression due to lumbar disc herniation or lumbar canal stenosis, dysfunction is not confined to degeneration at the site of compression but also extends to the motor neurons within the lumbar cord as a result of the axon reaction. Patients with weakness of lower leg should therefore be fully informed of the fact that these symptoms will not resolve immediately after surgery.

Multicenter Study Comparative Study
Outcomes of surgical treatment in male versus female adolescent idiopathic scoliosis patients.
This research was part of a multicenter study of the surgical treatment of adolescent idiopathic scoliosis (AIS). ⋯ Male AIS patients had slightly more rigid primary curves compared to females but a similar degree of postoperative scoliosis correction. Differences in the preoperative status and perioperative course did not compromise the outcomes of surgical treatment as in all other measures; the results were comparable between the genders.

Comparative Study
Improvements in general practitioner beliefs and stated management of back pain persist 4.5 years after the cessation of a public health media campaign.
Quasi-experimental, nonrandomized, nonequivalent, parallel group-controlled study involving before-after mailed surveys of general practitioners. ⋯ A population-based strategy to shift societal views about back pain has had a sustained effect on GP beliefs and stated behavior 4.5 years after its cessation.

A reliability study was conducted in quantitative 3-dimensional (3D) measurements for mild scoliosis. ⋯ The reliability of 3D reconstruction of the spine is acceptable, and this technique can be used for clinical studies.

A report of 4 cases of primary bone tumors (3 cases) or infection (1 case) at the cervicothoracic junction treated with resection-reconstruction. ⋯ The resection-reconstruction procedures, including the dissection, rerouting, and anastomosis between the internal thoracic vessels and the peroneal vessels, were successfully performed. At present, all patients are alive, and there is no evidence of recurrent disease, unchanged, or improved neurologic with a mean follow-up of 28 months. All grafts are well incorporated. CONCLUSIONS.: A combined low anterolateral cervical and midsternal approach or a midline sternotomy allows not only a safe and excellent exposure to the cervicothoracic junction but also to the internal thoracic vessels. The internal thoracic vessels are appropriate donor vessels: its longevity, diameter, length, and rerouting capacity allow vascularized graft reconstruction of vertebral column defects of the low cervical (C6-C7) and/or upper thoracic (T1-T3) region.
