Table 1.
Pre-operative and post-operative visual analog scale scores for various spine procedures.
| Procedure Group | Pre-Operative VAS | VAS One Week after Surgery | Pre-Operative VAS Declared after Six Months |
|---|---|---|---|
| MLD | 6.45 (SD = 0.57) | 1.52 (SD = 0.53) | 7.02 (SD = 0.48) |
| ACDF | 4.28 (SD = 0.76) | 1.11 (SD = 0.59) | 4.76 (SD = 0.88) |
| endoLIF | 6.00 (SD = 0.82) | 2.00 (SD = 1.41) | 5.00 (SD = 1.73) |
| PECD | 6.83 (SD = 1.09) | 2.33 (SD = 1.12) | 6.83 (SD = 1.09) |
| IELD | 6.19 (SD = 1.36) | 2.74 (SD = 1.46) | 8.30 (SD = 1.16) |
| TELD | 6.28 (SD = 0.91) | 1.57 (SD = 0.66) | 8.00 (SD = 0.59) |
Note: VAS score = visual analog scale score, ACDF = anterior cervical discectomy with fusion, endoLIF = endoscopic interbody fusion with percutaneous screw fixation, PECD = endoscopic posterior cervical discectomy, IELD = interlaminar endoscopic lumbar discectomy, TELD = transforaminal endoscopic lumbar discectomy.
