The study was carried out in 2 groups. Both groups have no differencies in Cobb angle, age and type of curves. T1 vertberal tilt( T1 tilt), first rib angee(FRA), clavicle angle (CA), coracoid process height(CPH), clavicle-rib cage intersection (CRCI), first rib cage height (FRCH), and trapezius lenght (TL) for shoulder balance; Cobb angle correction and central sacral vertical line distance to C7 plumb line for coronal balance; lomber lordosis ,thoracal kyphosis and sacral slope for sagittal balance are measured preoperative and postoperative. In DVR gruop all but one shoulder parameters were better than IDVR group. There is no diferencies in FRCH in both groups. Cobb angle correction was better in DVR group than IDVR group but no difference in thrunc shift. Thoracal kyposis and lomber lordosis were found minimally decreased and same in both group after surgery. As a result; we can say the patients who undergo DVR have better shoulder cosmesis and coronal correction than IDVR group.trCerrahi tedaviDengeErgenlerMedicalThesis
