Primary Outcome Measures:
  • CFU Density [ Time Frame: Surgical case CFU density will be determined at up to 1 month from completion of surgical cases ]
    Colony-forming unit density at incision site (CFU/m3)

Enrollment: 41
Study Start Date: November 2011
Study Completion Date: February 2015
Primary Completion Date: February 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: No device
Subject does not receive ABS system
Experimental: Air Barrier System device
Device is deployed adjacent to the surgery site and activated.
Device: Air Barrier System device
Device is deployed adjacent to the surgery site and activated.

Detailed Description:
The ABS is a device that uses localized clean air flow to shield a surgery site from ambient airborne contamination. This study examines the hypothesis that the ABS can reduce the presence of airborne colony-forming units at the surgery site during posterior spinal procedures.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
