Journal Title: Journal of Turkish Spinal Surgery - Year 2011, Vol 22, Issue 4
Abstract
In this study, patients (21 female, 5 male, mean age 15±2 years, mean follow-up period 60±22 months) with Lenke type 3 adolescent idiopathic scoliosis (AIS) treated with long segmental posterior instrumentation and fusion between the years 2000-2008 were evaluated retrospectively. Proximal thoracic, main thoracic, and lumbar/thoracolumbar Cobb angles, apical vertebral rotations (AVR), apical vertebra translations (AVT), kyphosis, lordosis and vertebral balance were evaluated in anterior-posterior (AP), lateral, traction and bending x-rays. In the early postoperative period, correction ratios, the amount of compensation, AVT, AVR, kyphosis, lordosis and vertebral balance were evaluated. In the final follow-up, coronal and sagittal correction losses and balance were evaluated and SRS- 30 form was used for clinical evaluation. Preoperative mean thoracic Cobb angle was 51° and mean lumbar Cobb angle was 44°. Early postoperative mean correction ratio was measured as 73 %, lumbar/thoracolumbar correction ratio as 77 %; in the last follow-up the mean correction losses were measured as 3 % in the thoracic region and 5 % in the lumbar region. In the sagittal and coronal planes, all cases were found within balance limits. There were no neurological deficits, pseudarthrosis and deep infections in any of our patients. According to SRS-30, total average was measured as 3,8. As a result, segmenter posterior instrumentation and fusion were sucsessfull in the treatment of Lenke type 3 AIS to achieve a significant correction degrees and stability in coronal and sagittal plane and to prevent from decompenzation.
