Abstract Background/Objectives It is to sustain the test accuracy and improve diagnostic capability of selfdeveloped aid in Dunn view to confirm modification of pistol grip in neck of femur that causes anterior femoro acetabular impingement. Method/statistical Analysis The test was performed before and after the usage of the self-developed aid in the patients referred to the test of Dunn view (45 and 90-degree flexion) who were scheduled with hip arthroscopy. α-angle and femoral head-neck offset were measured by oblique transverse images in MRI test and statistical significance was analyzed with paired T-test. Findings In the MRI images and Dunn 45° and 90° images before and after ancillary device use, as a result of measuring and analyzing α-angle, it was not statistically significant at 45° (P>0.05), but it was found there was statistical significance in 90° (P<0.05). In the MRI images and Dunn 45° and 90° images before and after ancillary device use, as a result of measuring and analyzing femoral head-neck offset, it was found there was statistical significance in both 45° and 90° (P<0.05). Improvements/Applications Upon the comparison results of unidirectional image and MRI test before and after the use of the aid in this study, statistically significant outcomes were found in 45 and 90 degree of Dunn view after the use of the aid. Therefore, it is considered that they could be used as the foundation data in the image studies with Dunn view.
