The Use of Computed Tomography-Based Navigation System for Biportal Endoscopic Lumbar Decompression.

Area of Science:

• Neurosurgery
• Orthopedic Surgery
• Minimally Invasive Spine Surgery

Background:

• Biportal endoscopic spine surgery requires detailed anatomical knowledge.
• Aberrant anatomy, degeneration, and deformities increase challenges in endoscopic lumbar decompression.
• Minimally invasive approaches demand high precision to avoid complications.

Purpose of the Study:

• To evaluate the efficacy and precision of computed tomography (CT)-based surgical navigation in biportal endoscopic lumbar decompression.
• To describe the application of CT-based navigation in managing complex lumbar compressive pathologies.

Main Methods:

• Utilizing a CT-based surgical navigation system integrated with the biportal endoscopic technique.
• Performing lumbar decompression for compressive pathologies under navigation guidance.
• Documenting surgical steps, indications, advantages, tips, limitations, and complication avoidance.

Main Results:

• CT-based navigation offers enhanced precision for careful decompression, minimizing bony work.
• The system helps prevent spinal instability and reduces the risk of wrong-level surgery.
• This approach is particularly beneficial for complex cases involving challenging anatomy or multilevel pathologies.

Conclusions:

• CT-based navigation is an effective and precise strategy for biportal endoscopic lumbar decompression.
• Its use is highly recommended in complex cases with anatomical variations or multilevel disease.
• This technology improves safety and accuracy in minimally invasive spine surgery.
