Abstract: Objective   To measure and analyze the morphological parameters of the acetabulum in Mongolian population of Inner Mongolia, so as to provide reference for acetabular prosthesis design and clinical surgery.    Methods     A total of 105 patients were randomly selected for pelvic CT examination at the Affiliated Hospital of Inner Mongolia Medical University and the Second People's Hospital of Ulanqab. Mimics 21.0 was used to reconstruct the acetabulum and measure the abduction angle, anteversion angle, suprainferior diameter, anteroposterior diameter and depth, and the results were statistically analyzed by using SPSS 25.0.    Results    The acetabular abduction angle, anteversion angle, suprainferior diameter, anteroposterior diameter and depth were (53.54±6.74) °, (16.16±4.93) °, (62.35±3.89) mm, (57.61±3.83) mm and (29.19±3.69) mm in males and (51.81±5.14) °, (17.45±4.59) °, (57.98±3.24) mm, (55.18±5.45) mm, (26.94±3.94) mm in females, respectively. There was no statistical difference in the acetabulum parameters between the same sex and different sides. There were statistical differences in the suprainferior diameter, anteroposterior diameter and depth between the different sexes. and these three parameters were larger in men, while there was no statistical difference in the acetabular abduction angle and anteversion angle between the different sexes There were differences in the acetabular morphology parameters between Mongolian population and other areas.    Conclusions    There are differences in acetabular parameters between Mongolian population in Inner Mongolia and other regions. The acetabular abduction angle, suprainferior diameter, anteroposterior diameter and depth are larger than other populations in southern China, and the acetabular anteversion angle is smaller. The differences of acetabulum morphology in different regions should be taken into account when designing prosthesis and placing prosthesis during surgery, the preoperative planning of the acetabular prosthesis should be done well in order to avoid blindness and randomness during surgery.
