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