Brief summary

The objective of this study is to determine whether the Air Barrier System (ABS) reduces airborne colony-forming units (e.g. bacteria) present at surgery sites during posterior spinal procedures

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.

Interventions

Device is deployed adjacent to the surgery site and activated.
