Pelvic and femoral osteotomies can be a challenge even for experienced orthopedic surgeons. Residual metal may complicate the insertion of the endoprosthesis in some cases. Sometimes, the anatomical modification of the previous osteotomy complicates the total hip replacement. This may require the use of an acetabular revision system for the primary implantation. Femoral deformities can require additional osteotomies of the femur during the implantation. In every case, accurate preoperative planning should be performed. A preoperative CT with 3D reconstruction is a powerful tool for further information beyond conventional imaging.
即使对于经验丰富的骨科医生来说，骨盆和股骨截骨术也可能是一项挑战。在某些情况下，残留金属可能会使假体植入复杂化。有时，先前截骨术的解剖结构改变会使全髋关节置换术变得复杂。这可能需要在初次植入时使用髋臼翻修系统。股骨畸形可能需要在植入过程中对股骨进行额外截骨。在每种情况下，都应进行准确的术前规划。术前CT三维重建是获取超越传统成像的更多信息的有力工具。
