Feasibility of Navigable Percutaneous Disk Decompressor (L'DISQ-C) for Cervical Disk Herniation

Area of Science:

• Neurosurgery
• Spinal Surgery
• Minimally Invasive Procedures

Background:

• Cervical disk herniation is a common condition requiring effective treatment.
• Minimally invasive techniques are sought to reduce surgical morbidity.
• The L'DISQ-C offers a novel approach to percutaneous disk decompression.

Purpose of the Study:

• To evaluate the procedural efficacy of the L'DISQ-C for cervical disk herniation.
• To assess the safety profile of the L'DISQ-C in cadaveric models.
• To determine the accuracy of wand tip navigation and thermal effects.

Main Methods:

• Intradiskal decompression performed on five human cadaveric cervical spines.
• L'DISQ-C used under C-arm fluoroscopic guidance.
• Evaluation of wand tip positioning, temperature variations, and histologic changes.

Main Results:

• Successful navigation of the L'DISQ-C tip into target regions in most cervical disks.
• Minimal temperature elevations (4.14–12.17°C) observed within the nucleus pulposus.
• Histologic examination revealed only minor denaturation at the procedure tract margin.

Conclusions:

• The L'DISQ-C demonstrated effective navigation to the posterior cervical disk target.
• Percutaneous decompression was achieved without significant thermal or structural damage.
• The L'DISQ-C shows promise as a safe and effective tool for cervical disk herniation.
