Coronal Imbalance after Selective Posterior Thoracic Fusion in Patients with Lenke 1 and 2 Adolescent Idiopathic Scoliosis

Figure 3

A 15-year-old female with Lenke 1CN adolescent idiopathic scoliosis underwent selective posterior thoracic fusion from T4 to T12. The preoperative coronal balance of 6mm (a) worsened to -24mm immediately after surgery (b), but recovered to -3mm at the final follow-up (c). The lumbar angle decreased from 30.2° in the early postoperative period to 17.5° at the final follow-up.
