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

Figure 2

A 15-year-old female with Lenke 1BN adolescent idiopathic scoliosis underwent selective posterior thoracic fusion from T4 to L1. The preoperative coronal balance of -2mm (a) worsened to 22mm immediately after surgery (b), but recovered to 1mm at the final follow-up (c). The lumbar angle decreased from 25.5° in the early postoperative period to 11.3° at the final follow-up.
