ABSTRACT

Purpose: The aim of this study is to evaluate the postoperative correction of thoracolumbar and lumbar idiopathic scoliosis treated with short posterior fusion. Methods: Retrospective analysis of 15 patients with thoracolumbar and lumbar idiopathic scoliosis treated with correction and short posterior fusion with minimum follow-up of 30 months. Inclusion criteria were: thoracolumbar and lumbar idiopathic scoliosis with non-structured compensatory curves, elasticity in lateral bending film, lateral trunk shift less than 3 cm, and no severe alteration in thoracic sagittal contours. The mean coronal Cobb angle of the main thoracolumbar curve was 44° (range, 38°-48°) and the Cobb angles of the compensatory curves on thoracolumbar or lumbar region were 18° (range, 12°-29°). Mean preoperative thoracic kyphosis was 28° (range, 23°-30°), and mean lumbar lordosis was 46° (range, 37°-62°). Mean rotation of apical vertebra was 22° (range, 23°-30°) and sagittal imbalance in frontal plane was 2.1 cm (range, 0.7-2.8 cm). Results: The mean Cobb angle of major curve was reduced from 44° to 12°, and the compensatory curves from 18° to 13°. Mean postoperative kyphosis angle and lumbar lordosis angles were 36° and 51° respectively. Rotation of apical vertebra was reduced from 22° to 16°, and sagittal imbalance from 2.1 cm to 0.7 cm. Conclusions: In selected patients, short posterior fusion shows good results in the treatment of thoracolumbar and lumbar idiopathic scoliosis. Using this technique with proper preoperative planning high correction rates can be achieved. Level of evidence: IV therapeutic study.
