Summary
A novel robotic needle guide (iSYS 1.3) enables accurate CT-guided bone biopsies. This system simplifies procedures, allowing precise needle placement in challenging bone lesions without readjustment.
Area of Science:
- Orthopedic surgery
- Medical robotics
- Diagnostic imaging
Background:
- CT-guided bone biopsies are crucial for diagnosing bone lesions.
- Accurate needle placement is essential for diagnostic yield and patient safety.
- Existing methods may require multiple adjustments, increasing procedure time and risk.
Observation:
- A novel robotic needle guide (iSYS 1.3) was evaluated for CT-guided bone biopsies.
- Preclinical testing involved swine vertebral bodies, followed by clinical evaluation in three patients.
- The system was mounted on a standard CT scanner table for transpedicular access.
Findings:
- The robotic system achieved accurate needle placement in the center of vertebral bodies in all preclinical and clinical cases.
- No needle readjustment was necessary during any biopsy procedure.
- All biopsies were performed successfully without complications, with CT scans confirming intrapedicular trajectories that avoided critical structures.
Implications:
- The iSYS 1.3 facilitates accurate and simple stereotactic bone biopsies.
- This robotic system can improve accessibility for less experienced teams in challenging anatomical regions.
- It holds potential to enhance the safety and efficiency of bone lesion biopsies.
