Learning curve as shown by logarithmic correlation between surgery series and operative time.
- Fig. 2
Twenty-four–month follow-up parameters versus preoperative measurements. ODI, VAS, SF-12 PC, SF-12 MC, and satisfaction are graded on their respective scales. Disc heights are given in millimeters. Range of motion is given in degrees. (post op, postoperative; pre op, preoperative.)
