Cervical extension is considered a risk factor for provoking radicular and spinal cord compromise. However, there have been no reports on the relation between extension strain (ES) and cervical spine disorders: degenerative cervical spine disorders, dynamic canal stenosis (DCS), and cervical myelopathy. We performed a cross-sectional study to investigate the relation. ⋯ These findings suggested that ES of the cervical spine is a risk factor for degenerative cervical spine disorders, and DCS and the aging process are risk factors for cervical myelopathy.

The Quick Disability of the Arm, Shoulder, and Hand (QuickDASH) questionnaire is a region-specific, self-administered questionnaire, which consists of a disability/symptom (QuickDASH-DS) scale, and the same two optional modules, the work (DASH-W) and the sport/music (DASH-SM) modules, as the DASH. After the Japanese version of DASH (DASH-JSSH) was cross-culturally adapted and developed, we made the Japanese version of QuickDASH (QuickDASH-JSSH) by extracting 11 out of 30 items of the DASH-JSSH regarding disability/symptoms. The purpose of this study was to test the reliability, validity, and responsiveness of QuickDASH-JSSH. ⋯ The Japanese version of QuickDASH has equivalent evaluation capacities to the original QuickDASH.

Serum interleukin-6 (IL-6) has been used for quantitative estimation of the surgical magnitude of major cardiac and thoracoabdominal surgery, but there have been few studies assessing IL-6 as a marker of surgical magnitude of spinal surgery. ⋯ Serum IL-6 on the first day varied depending on the surgical procedure used. Therefore, it might be a quantitative marker of surgical magnitude following spinal surgery.
