Accuracy of Freehand Versus Modified Funnel Technique for Pedicle Screw Insertion in the Thoracic Spine.

Aim: To describe a new pedicle screw insertion technique, a modification of the funnel technique, and to compare this technique with conventional freehand screw insertion regarding their accuracy and complications in the thoracic spine.

Material And Methods: Three hundred forty-three patients who underwent a posterior spinal fusion with different etiologies were retrospectively analyzed. In 84 patients, pedicle screws were placed using the freehand technique, and in 259 patients, the modified funnel technique was used.

Management and results of early-onset scoliosis with dual magnetically controlled growing rods: Additional preliminary results of spinal fusion surgery.

Objectives: The aim of this study was to evaluate the clinical and radiographic outcomes and complications of dual magnetically controlled growing rods (MCGRs) in the treatment of early-onset scoliosis (EOS) and to investigate the results of patients with definitive spinal fusion following MCGR.

Patients And Methods: A total of 15 patients (7 males, 8 females; mean age: 8.7±1.
