ALFADEK is a device created for Percutaneous Disc Decompression, by mechanical action, to remove part of the nucleus pulpous of intervertebral disc, for the treatment of radicular pain due to contained herniated disc. ALFADEK uses a particular helical probe based on the principle of Archimedes’ never ending screw. The auger tip of the probe, put into a specific cannula inserted in the disc, turning anticlockwise, collects portions of the nucleus pulpous of the disc, reducing the volume and its internal pressure and the pressure that the disc, herniated or protuberant, exercises on surrounding structures, determining the resolution of the disc-radicular conflict, with immediate reduction of radicular pain.

This procedure is appropriate at each level of the spine with great advantages for the patient. It’s mini-invasive, no pain, with no surgical incisions and with short hospital stay. It is made by local anesthesia under fluoroscopic guidance. Thanks to the particular system of the helical probe, it is possible to examine the disc material removed, that is collected, during the procedure, in a specific reservoir.
