Abstract:
Objective To study the accuracy in placement pediele screws with different method in the selection of entrance point in surgery of scoliosis.Method 27 cases with Lenke Ⅰ type of Adolescent Idiopathic Seoliosis(AIS)from Mar 2006 to September 2008,were retrospectively analyzed.14 eases were randomly divided into standard group(group A)and the entrance point was the same one as described in literatures.13 cases were randomly divided into individually group(group B)and the entran~point wag designed by surgeons on CT scans before surgery.There was no statistical difference in the mean age at time of surgery,Cobb angle on coronal and saggital(T5T12)plane,flexibility and rotational degree of apical vertebra preoperatively between two groups.Result There was no statistical difference in the time of surgery,blood losing,fixation segments,correction rate in Cobb angle and rotational degree of apical vertebra between two groups.The accuracy in placement pedicle screws in individually group was higher than that in control group(P＜0.01).Conclusion The accuracy in placement pedicle screws in the surgery of scoliesis can be improved by individual selection of entrance point.
