Comparative Analysis of Optoelectronic Accuracy in the Laboratory Setting Versus Clinical Operative Environment: A...

Area of Science:

• Medical technology
• Surgical robotics
• Image-guided surgery

Background:

• Robotic-assisted surgery relies on optoelectronic cameras for navigation.
• Discrepancies exist between camera accuracy in labs and clinical settings.

Purpose of the Study:

• To systematically review and quantify the accuracy of optoelectronic cameras in robotic surgery.
• To identify factors contributing to accuracy disparities between laboratory and clinical environments.

Main Methods:

• Systematic review of PubMed and Cochrane Library databases.
• Vetting 465 references, with 137 included in the analysis.
• Categorization into intrinsic, registration, and application accuracy.

Main Results:

• Intrinsic accuracy was <0.1 mm translation and <0.1° rotation.
• Laboratory platforms showed 0.1–0.5 mm translation and 0.1–1.0° rotation.
• Robotic-assisted spinal surgery accuracy was 1.5–6.0 mm translation and 1.5–5.0° rotation.

Conclusions:

• Maintaining optoelectronic data fidelity is crucial for robotic-assisted spinal surgery.
• Clinical environments introduce more error potential than laboratory settings.
• Improved planning, fiducial placement, registration, and workflow can enhance accuracy.
