Corrective Maneuvers Used in Different Scoliosis Deformities With the Experience of 72 Operated Patients

This study aimed to show the correction maneuvers used in scoliosis surgery and give hints and tips on achieving optimal correction with the help of visual content.

Seventy-two scoliosis patients with 96 major curves operated between 2011 and 2018 evaluated retrospectively. Seven different correction maneuvers (Ucar convex rod rotation technique, cantilever technique, convex double-rod rotation technique, convex double-rod translation technique, double-rod rotation with coronal bending, convex rod rotation with coronal bending, direct vertebral rotation) were used in these surgeries alone or together. Each method is explained with figures and videos. Type of scoliosis, follow-up time, age, preoperative and postoperative degree of curvature, amount of correction, surgical time, amount of transfusion, hemoglobin level, and hospital stay were evaluated.

The mean follow-up was 42.5 (24-108) months, and the mean age was 15.8 (12-29) years. The mean preoperative scoliosis angle of the patients was 75.9 (50-139) degrees, and the final follow-up was 15.6 (5-40) degrees. The scoliotic deformity correction rate was 79.3%. The mean preoperative thoracic kyphosis of the patients was 58.7 (12-110) degrees, and the final follow-up was 41.2 (25-62) degrees. The mean surgical time was 293 (160-440) minutes. The mean hospitalization length was 5.8 (2-21) days. The blood delivered to patients during surgery and postoperative was 715 (300-1800) mL. There was a statistically significant difference between the preoperative and final follow-up scoliosis angle ( P =0.000).

Providing an ideal correction without damaging the spinal cord depends on correctly applying the correction maneuvers. The use of correction maneuvers alone or in combination in the appropriate order will shorten the duration of the case, decrease the amount of bleeding, shorten the hospital stay, increase the amount of correction, and reduce complications.
