In a recent study, it was illustrated that there is an improvement of thoracic adolescent idiopathic scoliosis with surgery using pedicle screw. The surgery offers excellent clinical and radiological results in the very long term. 

This study was conducted to find the functional and radiographic outcomes in adolescents treated for thoracic idiopathic scoliosis using pedicular screws, with the follow-up of an average 20 years.

In this study, 109 patients were inspected. The radiographic data were assessed on fullspine radiographs (thoracic kyphosis, Cobb angle, pelvic tilt, lumbar lordosis, pelvic incidence). The Clinical data were assessed with Analog Pain Scale ODI, SRS-30 and SF-12. Listhesis below the arthrodesis and disc height were calculated.

Radiographic data were evaluated for 46 patients after 17.4 years. Mean Cobb angle was 58° before the surgery, and there was a mean correction of 40.1% with a loss of 5.3° at the final follow-up. Thoracic kyphosis and lumbar lordosis rose considerably at end follow-up. 

It was concluded that there is an improvement in very long-term clinical and radiographic results after posterior spinal fusion using pedicular screws for the treatment of thoracic adolescent idiopathic scoliosis.
