Abstract
OBJECTIVE: This study evaluated radiation exposure and operation time of percutaneous endoscopic lumbar discectomy (PELD) by using fluoroscopy-based navigation system for access and localization.
METHODS: 86 PELD cases performed by a single surgeon were retrospectively analyzed. Patients were separated into two groups: Group A (using a 3D-printed navigation instrument and fluoroscopy-based navigation system) and Group B (with conventional fluoroscopy and standard instrumentation) . The operation, fluoroscopy, and total access time were collected, as well as fluoroscopy and access times.
RESULTS: The operative time for Group A was 59 minutes (standard deviation (stdev), 6 minutes) and 106 minutes (stdev, 15 minutes) in Group B (p<0.001). In Group A, fluoroscopy was used an average of 5 times (stdev, 0.7) and 29 times (stdev, 8) in Group B (p<0.001). The fluoroscopy time was 9 minutes (stdev, 2 minutes) in Group A and 40 minutes (stdev, 8 minutes) in Group B (p<0.001). The number of times access attempts were 1.3 (stdev, 0.5) in Group A and 8 times (stdev, 2 times) in Group B (p<0.001). The total access time was 11 minutes (stdev, 2 minutes) in Group A and 28 minutes (stdev, 5 minutes) in Group B (p<0.001).
CONCLUSIONS: PELD using fluoroscopy-based navigation system showed lower operative, fluoroscopy, and access time compared to conventional techniques. In addition, fewer fluoroscopy images and access attempts were made in the navigation group. These data suggest that this novel technique reduces fluoroscopy, operation time and may reduce risks of repeated surgical access attempts.
