Clinical study of CD-Horizon in idiopathic scoliosis / 中国矫形外科杂志

ABSTRACT

[Objective]To discuss the effective method of idiopathic scoliosis and evaluate the result of screw-rod and screw-hook-rod system.[Method]From January 2000 to January 2004,85 cases with idiopathic scoliosis were treated by CD-Horizon instrument.Fifty-one cases were corrected with pedicle screws system only(group A),34 cases were applicated with pedicle hooks or vertebral plate hooks in thoracic vertebra,while with pedicle screws system in lumbar vertebrae(group B).The Cobb's angle of coronal plane and sagittal plane and horizontal plane malformation were compared in preoperative score,postoperative score and the score at 2 years follow-up.[Result]The mean followed-up duration of 85 cases was three years and a half.The coronal plane and sagittal plane correction rate of group A was higher than that of group B at postoperative and 2-year follow-up(P0.05).[Conclusion]Using CD-Horizon instrument is a very effective choice for patients with idiopathic scoliosis.Pedicle screw-rod system offers a significantly better curve correction compared with screw-hook-rod system.
