Overview

Radiofrequency neurotomy procedures work by disrupting pain signals that are sent from inflamed nervous tissue in the spine to the brain. The procedure is done on an outpatient basis and requires only local anesthetic and mild sedation, alleviating the possible complications of open surgery and general anesthesia.

Using fluoroscopic guidance, cannulae are carefully introduced in the areas of the spine to be treated. Electrodes are then inserted into each cannulae and a series of sensory and motor tests are administered individually at each needle site to confirm correct needle placement. After these diagnostic tests have been confirmed, a high frequency current is sent through the electrodes to heat up and lesion the surrounding nerve tissue. The lesions created disrupt the pain signals sent from the spine to the brain.

Patients typically go home within 1 to 3 hours and most are able to return to work and their normal activities within 24to 38 hours.

Use of the Stryker MultiGen Radiofrequency Generator gives physicians the ability to customize their procedures for optimal patient results. It is the only radiofrequency generator on the market able to handle up to 4 lesions at once, simultaneously and with independent control. Options for customization could include a single bipolar lesion, a mix of bipolar and single lesions, and any combination of thermal lesions and pulsed radiofrequency.
