A preliminary study on surgical navigation for epiduroscopic laser neural decompression

Area of Science:

• Minimally Invasive Spine Surgery
• Medical Imaging and Navigation

Background:

• Epiduroscopic laser neural decompression effectively treats lumbar spine pathologies like chronic low back pain, spinal stenosis, and disk herniation.
• High radiation exposure from fluoroscopy limits the widespread adoption of this procedure.
• There is a need for radiation-free guidance systems to improve safety and accessibility.

Purpose of the Study:

• To develop and evaluate a novel surgical navigation system for epiduroscopic laser neural decompression.
• To provide radiation-free image guidance during the procedure, reducing cumulative radiation doses.
• To assess the clinical feasibility and effectiveness of the proposed navigation system.

Main Methods:

• The system utilizes an electromagnetic tracking modality for real-time instrument localization relative to the patient.
• Point-based registration establishes the transformation between patient and medical image coordinate systems.
• The navigation system was applied to assist in epiduroscopic laser neural decompression procedures.

Main Results:

• The proposed surgical navigation system demonstrated clinical feasibility in assisting epiduroscopic laser neural decompression.
• The system successfully provided radiation-free image guidance during the procedures.
• Outcomes confirmed the effectiveness and safety of the navigation-assisted approach.

Conclusions:

• The developed radiation-free surgical navigation system is a viable tool for epiduroscopic laser neural decompression.
• This innovation addresses the limitations of radiation exposure, potentially increasing the application of this treatment.
• This represents the first reported application of surgical navigation for epiduroscopic laser neural decompression.
