Prospective reports will be collected on approximately 10,000 patients undergoing lumbar or cervical spinal surgery using intraoperative monitoring. Patients will be enrolled in registry after signing informed consent. Data will be collected prior to surgery, during surgery, immediately following surgery and 4 to 6 weeks post surgery. The registry will serve as a database for surgeries using IOM.
Specific outcome measures will be: neurological assessment, length of hospital stay, pain intensity, and complications.
