Abstract
Background: One method for treating adolescent idiopathic scoliosis (AIS), which is characterised by abnormal spinal alignment in the coronal, sagittal, and rotational planes, is surgical correction.
The two surgical techniques most typically used to correct spine alignment are Simple rod derotation (SRD) and Direct vertebral derotation (DVR)
Aim: The study’s goal was to assess the effectiveness of two treatment methods for adolescent idiopathic scoliosis: simple rod derotation and direct vertebral rotation.
Subjects and methods: A randomised controlled research involving 36 adolescents with idiopathic scoliosis was done. patients were randomly split into one of two groups: 18 patients in group A had DVR treatment, while 18 patients in group B received SRD with a 2-year follow-up.
Results: Apical Vertebral Rotation measured from CT scans in DVR group was 24.4° ±8.38° preoperatively and it decreased significantly postoperatively to 14.4°±4.61 °with (42.22%) correction rate while in SRD group it was 25.03°±7.99° preoperatively and it also decreased significantly postoperatively to a mean value of 21.41°±7.01° with (14.65%) correction rate. There were statistically significant differences between both groups postoperative (P<0.001)
Conclusion: The Apical Vertebral Rotation was greatly enhanced in both procedures, with Direct vertebral rotation being better. Both Simple rod derotation and Direct vertebral rotation reduce the rib hump, although the improvement is much greater with Direct vertebral rotation.
