Table 2 Comparison of surgery-related indicators between the two groups

From: Clinical outcomes of transforaminal endoscopic lateral recess decompression by using the visualized drilled foraminoplasty and visualized reamed foraminoplasty: a comparison study

Items VDF group (n = 45) VRF group (n = 42) P value
Radiation exposure time(s) 28.11 ± 7.13 15.48 ± 5.01 < 0.05
Operation time (minutes) 75.51 ± 15.63 66.07 ± 11.23 < 0.05
Time to return to work (days) 12.02 ± 3.50 10.95 ± 2.52 0.11
  1. The Radiation exposure time, operation time and time to return to work were verified by student t-test. P < 0.05 represented significance. VDF visualized drilled foraminoplasty, VRF visualized reamed foraminoplasty
