A 53-year-old woman with adult degenerative scoliosis. Anteroposterior-view radiograph (a) and lateral-view radiograph (b) before surgery. Low-temperature-plasma sterilization of the S2AI operation guide template before surgery (c). During the operation, the operation guide template was attached to the bone surface and secured for drilling, tapping, and screw placement along the axis of the screw trajectory (d). Postoperative follow-up anteroposterior (e) and lateral views (f) show that the deformity was well corrected, and the S2AI screw and other screws were in the desired places
