Collimation Reduces Radiation Exposure to the Surgeon in Endoscopic Spine Surgery: A Prospective Study
1Department of Orthopaedics and Traumatology, Faculty of Medicine, Çanakkale Onsekiz Mart University, Canakkale, Turkey.
Summary
Collimation significantly reduces surgeon radiation exposure during transforaminal percutaneous endoscopic lumbar diskectomy (PELD). This study demonstrates that using collimation during PELD is effective in lowering radiation doses for spine surgeons.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Medical Imaging
Background:
- No studies compare surgeon radiation dose between standard fluoroscopy and collimation during transforaminal PELD.
- Transforaminal PELD involves significant fluoroscopic radiation exposure for surgeons.
Purpose of the Study:
- To compare surgeon radiation dose during transforaminal PELD using standard fluoroscopy versus collimation.
- To evaluate the effectiveness of collimation in reducing radiation exposure for spine surgeons.
Main Methods:
- A single surgeon placed a gamma radiation dosimeter on their chest during transforaminal PELD surgeries.
- Patients were divided into two groups: nonforaminoplasty (24 patients) and foraminoplasty (13 patients).
- Radiation exposure was measured and compared between standard fluoroscopy and collimation within each group and overall.
Main Results:
- Surgeon radiation exposure was significantly lower when collimation was used in both groups and overall.
- Nonforaminoplasty group: 0.083 mSv (standard) vs. 0.039 mSv (collimation), p=0.019.
- Foraminoplasty group: 0.153 mSv (standard) vs. 0.041 mSv (collimation), p=0.001. Overall: 0.108 mSv (standard) vs. 0.039 mSv (collimation), p<0.001.
Conclusions:
- Collimation use during transforaminal PELD significantly reduces surgeon radiation exposure.
- Spine surgeons should consider implementing collimation during transforaminal PELD procedures to minimize radiation risk.
