Fluoroscopic Radiation Exposure during Percutaneous Kyphoplasty

Area of Science:

• Medical Imaging
• Radiation Safety
• Orthopedic Surgery

Background:

• Fluoroscopic guidance is essential for kyphoplasty (KP).
• Surgeons are exposed to real-time radiation during procedures.
• Understanding radiation exposure is crucial for operator safety.

Purpose of the Study:

• To measure surgeon radiation exposure during kyphoplasty.
• To assess the impact of X-ray beam direction on radiation dose.
• To identify optimal positioning for radiation dose reduction.

Main Methods:

• Observational study of 84 patients undergoing kyphoplasty.
• Categorization into four groups based on X-ray beam direction.
• Dosimetry badges measured surgeon radiation exposure (28 badges total).

Main Results:

• Radiation exposure occurred during approximately 50% of the procedure time.
• The chest received the highest radiation dose.
• Positioning the X-ray tube away from and below the surgeon significantly reduced radiation levels (2.7-10 fold difference).

Conclusions:

• Optimal X-ray tube positioning is critical for minimizing surgeon radiation exposure during fluoroscopic-guided kyphoplasty.
• Positioning the X-ray tube below the table and opposite the operator is recommended.
• Adherence to recommended positioning can reduce radiation dose by 2.7 to 10 times.
