Summary
Robotic-assisted CT-guided bone procedures are feasible and accurate, with a 98.9% success rate for needle insertion. This innovative technique shows promise for future orthopedic and oncologic interventions.
Area of Science:
- Orthopedic Surgery
- Medical Robotics
- Interventional Radiology
Background:
- Percutaneous bone procedures are crucial for diagnosis and treatment.
- Robotic assistance offers potential for enhanced precision and safety in minimally invasive interventions.
- Current robotic platforms require evaluation for CT-guided bone applications.
Purpose of the Study:
- To assess the feasibility, safety, and accuracy of robotic-assisted CT-guided percutaneous bone procedures.
- To evaluate the Epione® robotic platform in spinal and pelvic bone interventions.
- To establish preliminary data for future large-scale comparative studies.
Main Methods:
- Prospective multicenter pilot study involving 34 adult patients.
- Utilized the Epione® robotic platform for CT-guided percutaneous bone consolidation or tumor ablation.
- Measured feasibility, safety, targeting accuracy (lateral and angular deviation), procedure time, and radiation dose.
Main Results:
- Robotic needle insertion was feasible in 98.9% of 90 procedures across spine and pelvis.
- Mean lateral tip deviation was 2.0 mm and mean angular deviation was 3.1°.
- 17.6% of patients experienced adverse events, with none related to the robotic device or procedure.
Conclusions:
- Robotic-assisted CT-guided bone procedures demonstrate high feasibility and accuracy.
- The technique is safe, with no device- or procedure-related adverse events observed.
- Further investigation in larger comparative studies is warranted.
