Computed Tomography-Based Navigation for Total Hip Arthroplasty

  • Nobuhiko Sugano


CT-based navigation systems have been reported to be more accurate than conventional methods and even than imageless navigation in total hip arthroplasty. Although there is additional cost for preoperative CT images and it requires preoperative planning time, it may reduce the implant inventory cost by precisely predicting implant size and OR time by reducing the decision-making time regarding the final implant size and modular parts selection. It is particularly useful for complex cases such as DDH and post-traumatic deformities. It can be used through any surgical approaches or patient positions on the OR table. It can be used with either cementless or cemented implants. It can be also used for revision surgery. Because CT-based navigation accurately determines the best positioning and alignment of instruments and implants, it smooths the path for less-invasive THA with limited anatomic exposure.
