Clinic value of female pelvic shape in South of China
Objective To analyze the current situation of the shape and size of female pelvic inlet in South China and to explore its trends. Methods 844 images and clinical data of female patients with gynecological diseases who underwent CT scan in Nanfang Hospital were collected and 3D model of pelvis was reconstructed for measurement ofthe transverse and anteroposterior diameter, and then judgement of the shape of their inlet. Those patient were divided into 3 groups according to the age. Patients was an ageunder 40 years was assigned into the first group, between 41 to 50 years assigned into the second group, over 50 years assigned into the third groups. The shape and size of pelvic inlet in the three groups were explored, and the relationship between age and the shape and size of pelvic inlet was also explored. Result (1)The morphologic classification of 844 female pelvic inlets among 3 groups was significantly different(P<0.001) . (2)Transverse diameter of pelvic inlet and anteroposterior diameter of pelvic inlet differences among the 3 groups had statistical significance（P＜0.001）. (3)Age was negatively correlated with the anteroposterior diameter of the pelvic inlet（r=-0.292，P＜0.001）. (4)Pelvic inlet area for each groups was also significantly different（P＜0.001）. Conclusion The shape of the female pelvic inlet in south China has changed in the last 30 years, with being transversely oval more common than being verticallyoval. This trend is beneficial to engagement of vaginal delivery.
