Expert Review & Medical-Legal Consultation

Dr. Calancie provides independent expert review in selected cases involving neurological deficits after spine surgery.

His background in spinal cord injury, intraoperative neuromonitoring, Motor Evoked Potential testing, EMG, and pedicle screw stimulation makes him well suited to evaluate complex surgical events in which a patient awakens with a new postoperative neurological deficit.

The purpose of this work is to provide clear, evidence-based interpretation of the available neurophysiologic and clinical record.

Areas of Review

Dr. Calancie’s expert review may include assessment of:

  • Intraoperative neuromonitoring records

  • Motor Evoked Potential responses

  • EMG activity during spine surgery

  • Pedicle screw stimulation data

  • Alarm criteria and warning signs

  • Timing and possible mechanism of neurological injury

  • Relationship between intraoperative events and postoperative deficits

  • Spinal cord injury prognosis and recovery potential

Intraoperative Neuromonitoring Interpretation

Many spine surgery cases involving postoperative neurological deficits depend on careful interpretation of the intraoperative neuromonitoring record.

Key questions may include:

  • Were there changes in MEP, EMG, or other monitoring signals?

  • Were warning signs present?

  • Were the warning signs recognized?

  • Were the responses to those warnings appropriate?

  • Is the pattern of change consistent with a particular mechanism of injury?

  • Does the record support or fail to support a causal relationship between surgical events and postoperative outcome?

Dr. Calancie’s experience developing and validating neuromonitoring approaches provides a strong foundation for this type of review.

Pedicle Screw Placement and Neural Injury

Dr. Calancie has particular expertise in the use of stimulus-evoked EMG and pulse-train stimulation for evaluating pedicle screw placement during spine surgery.

This experience is relevant in cases where a postoperative deficit may involve:

  • Medial pedicle wall breach

  • Nerve root irritation or injury

  • Spinal cord compromise

  • Screw trajectory or placement concerns

  • Interpretation of stimulation thresholds

  • Adequacy of intraoperative feedback

His laboratory’s work in this area included development of monitoring methods and a randomized, blinded clinical trial evaluating pulse-train stimulation during thoracic pedicle screw implantation.

Independent, Evidence-Based Opinion

In medical-legal matters, Dr. Calancie’s role is not to advocate for a predetermined conclusion. His role is to evaluate the record and provide an independent opinion grounded in neurophysiology, surgical monitoring principles, and the available clinical evidence.

This may include identifying what the data support, what they do not support, and where uncertainty remains.
