The hypothesis of this study is to find evidence if there is an influence of spine surgery on the serum levels of two proteins secreted from neuronal cells.

Spinal Injury

Primary Outcome Measures:
  • S-100B levels [ Time Frame: 4 hours ]
    average timeframe between blood withdrawal (twice, pre-and post-operatively)

Biospecimen Retention:   Samples Without DNA
serum levels of the biomarkers S-100B and NSE are measured

Estimated Enrollment: 30
Study Start Date: March 2013
Study Completion Date: November 2013
Primary Completion Date: November 2013 (Final data collection date for primary outcome measure)
Spine surgery
Patients undergoing spine surgery
Bone surgery
Patients undergoing bone surgery for fracture treatment other than spine fractures

Detailed Description:
The question, if there is an effect on the cerebrospinal system during spine surgery, which can be traced by monitoring serum levels of neuromarkers is not yet answered. This study has its background from other studies on patients with traumatic brain injury (TBI), in whom elevated serum levels of the two neuromarkers S-100B and NSE are associated with injury severity, neuronal damage, brain, tissue damage, and outcome. Patients undergoing spine surgery with or without pre-existing traumatic neurologic symptoms are planned to be the study cohort. Pre- and postoperatively the serum levels of S-100B and NSE are obtained and are statistically compared with patients undergoing other types of bone-related surgery.
