For the study, researchers followed 45 patients who underwent procedures between 1996 and 2004. There were 28 thoracic and 17 thoracolumbar procedures. The patients had curves less than 85 degrees and were operated on with a total discectomy, bone-on-bone apposition and dual-screw, dual-rod fixation.
Patients experienced an average of five vertebrae (four discs) instrumented and an average hospital stay of 9.1 days. The average preoperative curve for the thoracic patients was 52.5 degrees and the final postoverate curve was 27.9 degrees. The average preoperative curve for the thoracolumbar patients was 50.5 degrees, which became 18.3 degrees postoperatively.
For all patients, the sagittal and coronal balance was restored. There were no neurologic, vascular, pulmonary or implant-related complications reported.
