MATERIAL and METHODS: We conducted a retrospective study among 53 Lenke Type 1 AIS patients who underwent corrective surgery at our centre between 2006 and 2012. Patients were classified as group 1 if they underwent selective surgery and as group 2 if they underwent non-selective surgery. Surgical results of preoperative and postoperative sagittal and spinopelvic measurements, pelvic tilt (PT), pelvic incidence (PI), sacral slope (SS), lumbar lordosis (LL) and thoracic kyphosis (TK) values were analysed using the SURGIMAP Software (Nemaris nc. USA) measurement system.

RESULTS: In both groups, a comparison of pre- and postoperative sagittal spinal parameters did not show a statistically significant difference. In both groups, pre- and postoperative measurements of LL and TK did not show a statistically significant difference.

CONCLUSION: After selective and non-selective surgery, sagittal spinal and spinopelvic parameters are not affected in the middle term. We think that the long-term studies to be done in this regard will increasingly require the necessity of keeping the pelvis in mind while evaluating the sagittal plan in AIS surgery.
