Figure 1From: Radiological assessment of shoulder balance following posterior spinal fusion for thoracic adolescent idiopathic scoliosisFourteen-year-old girl with Lenke type 2C adolescent idiopathic scoliosis. A, The preoperative Cobb angle of the PT and MT curves were 50° and 78°, respectively. B, Immediately after surgery, the PT and MT curves were corrected to 28° (44.0%) and 17° (78.2%), respectively. The PTC:MTC ratio was calculated as 0.56. This patient had postoperative shoulder imbalance (RSH: +22mm). C, Five years postoperatively, the RSH had decreased to +6 mm and the postoperative shoulder imbalance had improved. Consent for publication of this figure was obtained from the patient's parents.Back to article page
