Three-dimensional templating in hip arthroplasty: the basis for template-directed instrumentation?

Introduction Computed tomography-based three-dimensional models may allow the accurate determination of the center of rotation, lateral and anterior femoral offsets, and the required implant size in total hip arthroplasty. In this cadaver study, the accuracy of anatomical reconstruction was evaluated using a three-dimensional planning tool. Materials and methods A total of eight hip arthroplasties were performed on four bilateral specimens....
