35. How many screws are necessary to be considered an experienced surgeon for freehand placement of thoracolumbar pedicle screws? Analysis of the learning curve using the cumulative summation test for learning curve (LC-CUSUM)

Several studies have demonstrated the learning curve for freehand pedicle screw placement (PSP) in residents, spinal fellows, and young surgeons. Also, the authors have suggested the numbers of required screws for PSP. Despite advances in statistical analysis for the learning curve, there is no study investigating how many screws are required to reach an adequate performance level in freehand PSP.
