中文摘要:
目的：通过术前术后对髋关节前倾角及髋臼壁发育情况的观察，探讨螺旋CT三维重建技术在儿童发育性髋关节脱位(DDH)治疗中的应用价值。
方法：2003年6月至2007年6月，发育性髋关节脱位53例(61髋),男12例，女41例；左侧34例，右侧11例，双侧8例；年龄3～16岁，平均5. 6岁。行双侧髋关节螺旋CT三维重建检查，测量前倾角(FNA)及髋臼壁的发育情况，与术中所见比较。采用Pemberton或Chiari骨盆截骨及股骨近端旋转截骨治疗，术后复查三维CT,测量FNA,观察新髋臼的情况，与术前进行比较。
结果：53例患髋前倾角均增大，最大90°，最小35°，平均(45.6±11.4)°。正常45髋前倾角为(23. 5±10.2)°。髋臼各壁不同程度发育不良，与术中所见符合。术后前倾角较术前明显降低，前倾角平均(15.6±5.8)°。髋臼对股骨头包容明显改善。
结论：髋关节螺旋CT三维重建技术可以全面显示髋关节的病理形态，精确地测量FNA,对术者选择适当的治疗方案具有重要的指导意义，术后能更直观地判断手术效果，评估预后。 |

ABSTRACT
Objective: To investigate the value of 3-dimensional CT in the treatment of developmental dislocation of hip (DDH).
Methods: From 2003.6 to 2007.6, the femoral neck anteversion(FNA) and morphology of acetebulum in 53 patients with DDH(61 hips) were studied by three-dimensional CT imaging. Among the patients,12 patients were male and 41 patients were female, ranging in age from 3 to 16 years(mean 5.6 years). Thirty-four patients had dislocation in left hip joint,11 patients had dislocation in right hip joints,and 8 patients had double dislocations. The patients were treated with Pemberton or Chiari acetabuloplasty and femoral osteotomy. After operation all the cases were obeserved by 3-dimensional CT again. The femoral neck anteversions were measured and the shapes of new acetabulum were observed.
Results: Among 61 hips of DDH,the maximum femoral neck anteversion was 90°.The minimum was 35°and the average was(45. 6±11.4)°.Among 45 normal hips,the average femoral neck anteversion was(23. 5±10.2)°.The acetabulum were dysplastic according with what were found in the operation. After operation the femoral neck anteversions decreased and averaged(15. 6±5. 8)°.The femoral head containment improved.
Conclusion: The advantages of 3D CT scan includes manifestation of acetebular morphology,correct measurement of femoral neck anteversion and evaluation of operative procedure and efficacy. The 3-dimensional CT method is deserved to use widely in the treatment of developmental dislocation of hip in children. |
