ABSTRACT
Restoration of the sagittal alignment is one of the fundamental goals in scoliosis correction surgery. Having an increase in popularity of segmental spinal instrumentation, thoracic kyphosis [TK] is often sacrificed to achieve frontal and axial plane correction. Patients with a Lenke type 1 deformity underwent selective thoracic fusion [lowest instrumented vertebra of T12 or L1] using corrective segmental spinal instrumentation [Hook-Rod] and were followed up for 2 years. They were evaluated before and after operation for coronal and sagittal alignments using standing anteroposterior and lateral radiographs. There were 63 patients [21 male, 42 female] with a mean age of 15.8 +/- 2.1 years included to this study. TK reduction had significant correlation [P
