For anterior correction and instrumentation of thoracic curves single rod techniques are widely used. Disadvantages of this technique include screw pullouts, rod @entity174 and limited control of @entity1513 . This is a prospective study of 23 consecutive @entity1 with @entity1514 treated with a new anterior dual rod system. Aim of the study was to evaluate the safety and efficacy of this new technique in the surgical treatment of @entity1514 . To the best knowledge of the authors, this is the largest series on dual rod dual screw instrumentation over the entire fusion length in @entity1514 . Twenty-three @entity1 with an average age of 15 years were surgically treated with a new anterior dual rod system through a standard open double thoracotomy approach. Average clinical and radiological follow-up was 28 months (24-46 months). Fusion was carried out mostly from end-to-end vertebra. The primary curve was corrected from 66.6 degrees to 28.3 degrees (57.5% correction) with an average loss of correction of 2.0 degrees at Cobb levels and of 1.3 degrees at fusion levels. Spontaneous correction of the secondary lumbar curve averaged 43.2% (preoperative Cobb angle 41.2 degrees ). The apical @entity717 was corrected by 41.1% with a consecutive correction of the rib hump of clinically 66.7%. The @entity1513 measured 29.2 degrees preoperatively and 33.6 degrees at follow-up. In seven @entity1 with a preoperative hyperkyphosis of on average 47.3 degrees @entity1513 was corrected to 41.0 degrees . This new instrumentation enables an entire dual rod instrumentation over the whole thoracic fusion length. It offers primary stability without the need of postoperative bracing. Dual screw dual rod instrumentation offers the advantages of a high screw pullout resistance, an increased overall stability and satisfactory sagittal plane control.
