“…This second concern may not be of major importance. Huppertz et al [18] have reported that preoperative CT for THA is associated with slight but justifiable increases in both radiation exposure and per-patient cost.…”

“…A further limitation of the mechanical device, as used in the current study, is that it is based on preoperative CT imaging. Although the true cost of a CT for hip planning is only 53 Euros and requires only a body mass index-dependent mean effective dose of 4.0 mSv for the bone detail [6], the use of plain radiographs for threedimensional planning would certainly be more practical.…”

Background Although surgical navigation reduces the rate of malpositioned acetabular cups in total hip arthroplasty (THA), its use has not been widely adopted. As a result of our perceived need for simple and efficient methods of navigation, we developed a mechanical navigation device for acetabular cup orientation. Questions/purposes We assessed accuracy of cup orientation (mean error of cup inclination and anteversion) of a novel mechanical navigation device, percentage of outliers, length of operation, and compared the results with a series of CT-based computer-assisted THAs.Methods Cup orientation of 70 THAs performed using the mechanical navigation device was compared with a historical control group of 146 THAs performed using CT-based computer navigation. Postoperative cup orientation was measured using a validated two-dimensional/ three-dimensional matching method. An outlier was defined outside a range of ± 10°from the planned inclination and/or anteversion. Results Using the mechanical navigation device, we observed a decrease in the errors of inclination (1.3°± 3.4°[ range, À6.6°to 8.2°] versus 3.5°± 4.2°[À12.7°to 6.9°]), errors of anteversion (1.0°± 4.1°[À8.8°to 9.5°] versus 3.0°± 5.8°[À11.8°to 19.6°]), percentages of outliers (0% versus 9.6%), and length of operation (112 ± 22 [78-184] minutes versus 132 ± 18 minutes) compared with CT-based navigation. Conclusions Compared with CT-based surgical navigation, navigation of acetabular cup orientation using a mechanical device can be performed in less time, lower mean errors, and minimal equipment.
