Application of Three-Dimensional Computed Tomography for Detecting Femoral Neck Anteversion in Development Dislocation of Hip in Children

Objective To evaluate the value of reconstruction of three-dimentional CT in development dislocation of hip(DDH)in children.Methods Twelve cases of DDH concluded 4 bilateral and 8 unilateral cases.To sum up,16 sick hips were operated and 8 normal hips were also obtained by three-dimensional CT(Hip speed Fi/x,GE Co).Results 3D reconstruction were used to show femoral head,(acetabulum) and relationship of acetabulum and femoral head respectively.The difference between FNA measurement of sick hips and those of normal hips were significant(P0.05).Conclusion Three-dimensional CT of hip increases the information of imaging and affords the new technical support to relat diagnosis and individual therapy of DDH.
