Image-guided thoracoscopic spinal surgery: a merging of 2 technologies

Area of Science:

• Neurosurgery
• Spinal Surgery
• Medical Technology

Background:

• Thoracoscopic spinal surgery presents significant orientation challenges due to complex 3D anatomy and 2D imaging limitations.
• Frameless stereotactic image guidance aims to overcome these difficulties.

Purpose of the Study:

• To quantitatively assess the application and effectiveness of frameless stereotactic image guidance in thoracoscopic discectomy.
• To evaluate the impact of image guidance on accuracy, efficiency, and patient outcomes.

Main Methods:

• Retrospective review of clinical and intraoperative navigational data from 16 patients.
• Analysis of registration (calculated) and navigation (intraoperative) errors to determine accuracy.
• Review of clinical outcomes and complications.

Main Results:

• Achieved high accuracy with registration error of 1.7 mm and navigation error of 1.2 mm.
• The initial time investment for image guidance was offset by procedural efficiencies.
• Clinical outcomes and complication rates were comparable to previous experiences.

Conclusions:

• Image-guided thoracoscopic spinal surgery significantly improves 3D orientation during 2D imaging procedures.
• This technology enhances accuracy, efficiency, and safety in thoracoscopic discectomy.
• Continued integration of guidance technology with surgical procedures is anticipated.
