Abstract
Described herein are method, systems and devices for measuring the region adjacent to or around a nerve root, such as the space within an intervertebral foramen before, during and/or after a spinal decompression procedure. Measurement devices may be advanced by pulling on them using a guidewire passing through the intervertebral foramen and out of the subject. The measurement device may include sounds for determining one or more dimensions of the space around a nerve root within an intervertebral space, lateral recess or central canal. Various embodiments of sounds, including calibrated, inflatable, expandable, moldable, and tapered sounds (or combinations of these) are described.
