Intraoperative neurophysiological monitoring

Real-time monitoring of peripheral nerves

OSIRION I offers a fast introduction to intraoperative neuromonitoring. OSIRION I is a system for recording electromyographic signals and for stimulating peripheral nerves.

Action potentials triggered by stimulation are recorded electromyographically (EMG) from the muscles using needle electrodes or surface electrodes attached to a ventilation tube, and converted into an optical and acoustic signal. The measurements can be very easily interpreted by the surgeon.

Neuromonitoring helps the surgeon to localize and identify nerve structures at the surgical site. The procedure also provides the operating surgeon with the opportunity to constantly monitor the functionality of the nerves during surgery, so as to ensure that the function of the nerves is preserved and minimal damage is caused.

There is a risk to the integrity of the spinal cord and spinal nerves during spinal surgery due to the corrective forces being exerted on the spine, the surgical opening of the spinal canal, implantation, and related procedures.

Hence, neurological damage can result from a variety of mechanisms and may occur at almost any stage of the operation. So as to promptly detect and respond to any such incident, intraoperative monitoring of spinal nerve function is essential if the risk of postoperative neurological deficits is to be minimized.
