A total of 96 patients consented to participate in the initial prospective study,CONSORT study flow diagram.There were no differences in demographics (Demographics and radiological analysis between patient groups. Values are the actual numbers or reported as mean ± standard deviation.BMI, body mass index.The use of screws to supplement cup fixation had a significant effect on the proximal migration of the acetabulum cups (Comparing proximal migration (y-axis translation) between cups fixated with or without screws (Translations and rotations of the acetabulum cup from the 2-week baseline exam between screw and no screw fixation groups. Values are reported as mean ± standard deviation.Within the screw fixation group, 24 patients received 1 screw and 18 patients received 2 screws. There was 1 patient who received 3 screws and was excluded from the following analysis. There was no difference in the inclination angle or the anteversion angle between these patients (Comparing proximal migration (y-axis translation) between cups fixated with 1 or 2 screws (Further, there were 11 patients who were excluded from the presented analysis for deviating from their study arm; six patients underwent the DA approach but did not receive screws and five patients underwent the DL approach but received 2 screws. There was no significant difference in the inclination or the anteversion angle between these groups (
