| The pelvis is an important component in the human skeletal system, in women, the pelvis is closely related to pregnancy, childbirth and various gynecological diseases. Pelvis is playing an important role in human body.Due to the limitations of the research methods, it has been unable to depth understanding. Since1895the X-ray was discovered, Scholars at home and abroad have found an increasingly wide utilization in pelvic measurement. Chinese scholars begined to focus on the female pelvis since the50’s of last century. In the following30years, They finished a large-scale study in pelvic measurement by X-ray and mde a great contribution to the clinical obstetrics. From1983to1985, Shuwen-Wang and Lian Yue et al organized and coordinated the female pelvic measurement work flow. The following three years, data collected were analysed and statistics were released finally. The research has thrown up some differengts between the Han and Uighur women pelvis, but the research had focused on the300women In the Tianshan Mountain and Manas County. Great changes have taken place in the social culture, economy, life habit, but the research on the pelvic measurement stagnated. Foreign research shows that the female pelvis morphology and diameter have changed enormously over the last20or30years. The overall trend of these changes is not conducive to the natural delivery. Nowadays, The clinical data of female pelvis without the ethnic and regional differences originate from the "information" twenty years ago.Xinjiang is a multi-ethnic region inhabited by different races. Uighur ethnic group is a Mixed race by the Caucasus and Mongolia while Han belongs to the Mongolia race.According to foreign theory and practice, There were significant differences in pelvic diameters among different species and the result is agreeable with one by chinese scholars. In1987, one hundred Uighur women pelvises and one hundred Han female pelvises were measured and their characteristics were analyzed by Xiufeng-Li. There were significant differences between group Uighur women and group Han female. After20years, there was no further study on the female pelvis in Xinjiang area. The study cannot fully represents Xinjiang female pelvis now for its time too long, meanwhile200women is quite a small sample, so the results should be treated cautiously.With the development of computer technology and computer graphics, medical imaging technology has a great improvement. CT and MR were used for female pelvic research, including Obstetric diameter measurement, noninvasive prenatal diagnosis and some gynecological diseases diagnosis and treatment. China lags behind other nations in the field of scientific study. As China’s economic development and the living standards of residents upgrading, the pelvis maybe probably change, how to evaluate these effects and what is its significance clinically? That is a question. For the purpose of promoting national reunification, ethnic unity,social stability and reducing medical disputes, it’s necessary to an in depth study of the female pelvis in Xinjiang area.A workman must sharpen his tools if he is to do his work well. The classical method is X-ray pelvimetry. Due to the influence of shooting angle and patient position, pelvic midplane blind zone, two-dimensional pictures, large amounts of radiation, there exists defects in X-ray pelvimetry. In recent years, the female pelvic research method already changed with computer development. The real-time image processing technology has extensive application foreground in medicine area. The core technology is3D reconstruction. This method changes two-dimensional images into three-dimensional model with the help of reverse engineering software. In a word, The real-time image processing technology is a state-of-art anatomical research method.China is a country with Han nationality as the main body, multi-ethnic country, Part of minority and Han nationality is not the same. Due to the nutrition, living and working habits and regional difference, pelvic diameter has regional and ethnic characteristics significantly.By using digital technology, Research on female pelvis which focus on the Southern Chinese Han women has just started. The technique is not applied to the comparative study between Uighur women and Han women yet. Uighur women in xinjiang area have more multiple delivery history. The rate of repeat cesarean section is higher than that of other areas, and therefore the rate of bad healing of incision is higher. Strictly control the indications for cesarean section is particularly important in the region. Besides the objective factors and social economy, also includes the clinicians in relative cephalopelvic disproportion standard master less accurate. The original pelvic methods have great limitations. Current clinical pelvis measurement method only provide an indirect evaluation of bony. Internal pelvimetry and pelvic morphology are closely associated with the natural childbirth, but these cannot be evaluated now. With the help of three-dimensional reconstruction of digital technology, pelvic factor can be more accurate and detailed assessment.With the help of geomagic software and ug software,this subject adopting digital three-dimensional reconstruction technique made the digital pelvimetry possible. We have received many data of pelvimetry for our research into the female pelvis in Xinjiang area. Taking into account the differences of nationalities, regions is very important in clinical practice. As for the small amount of sample and the age limitations, more accurate and comprehensive data would be left behind to further research.Part one:Based on digital Three-Dimensional reconstruction and measurement in vivo CT raw data of the normal female pelvic[Objective]Three-dimensional digital reconstruction used in clinical is called for mastering the relevant computer software operation, image data acquisition and storage, it is different from the general clinical CT or MRI routine data storage. Computer pelvic3D reconstruction based on CT scanning is used in vivo data directly, can most reflect the anatomy of human body.Application of female pelvic CT scan data combined with the software Mimics to construct medical interaction in female pelvic three-dimensional digital model, combined with Geomagic software, UG software,3D pelvic model for reconstruction of the random scaling, cutting and arbitrary rotation angle, not only can accurately measure directly related morphological anatomy, obstetric diameter and angle of the pelvis, but also of gynecological preoperative evaluation, operation simulation is used to reduce the human factor influence, the traditional measurement, more truly reflect the physiological condition of pelvis.Digital model and simulation platform for female obstetrics and gynecology diseases, diagnosis and treatment.

Convenient in clinical application to establish individual virtual pelvis, providing a technical platform for the relevant research.Part twoUighur female pelvic of Xinjiang digital three-dimensional model reconstruction and Pelvic measurement [Objective]Foreign research shows that:The different nutrition, life, work habits and region may impact the pelvic morphology and characteristic, the pelvic morphology has obvious regional and ethnic characteristics. To understand Xinjiang uygur femal normal pelvic morphology changes. We reconstructed the Xinjiang uygur women’s normal pelvic based on CT three-dimensional model reconstruction, measured the pelvic main longitudinal measurement, concluded the modern xinjiang uygur female of child-bearing age physiological constant value of the pelvis, cleared the pelvic fine anatomical features and obstetric physical constants, and we had reconstruct the normal female pelvic successfully before. In the process of measurement, we found that the ratio of tail joint abnormal in the Uighur women is relatively high. So, we measured the detailed morphological and physiological constant of the sacrum.The first section:materials and methods1.the research object:From2012January to2013January, in the people’s Hospital of Xinjiang autonomous region, Hetian People’s Hospital, Yili Xinhua hospital image center, the100Han and100Uighur fertility active women, age25-40years old, mean age (31.6±6.7) years old, were selected. All women living in Xinjiang, the body upright, legs of normal development, and they have at least a full-term pregnancy, vaginal birth history, neonatal birth weight between 2500g-4000g, eliminate pathological pelvis.2, Software and equipment,3D reconstruction and measurement method was mentioned in the first part. Split the sacrum use the tool of Edit Masks in the Mimics10.01. Create the three-dimensional digital model of the sacrum separately. Sacral digital model into UG software, on the sacrum, sacral camber length, anterior sacral foramina and the posterior sacral foramina transverse diameter, vertical diameter, hole iliac line distance, sacral hiatus width and depth were measured.4. Statistical methods SPSS13.0statistical software was used for statistical observation of the index, mean and standard deviation of each data.The second section:the results1, Using the CT scan raw datac of the Uighur women pelvic and the3D reconstruction technology, and combining the Mimics soft, we can reconstruct the complete pelvis successfully, We can also split the pelvic use the Geomagic software, such as the left and right side of the pelvis and sacrum. The model of the Xinjiang uygur female pelvics were clear, arbitrarily scaling, cut and rotation in any angle. The measurement of bstetric physical constant of pelvic was used Mimics and UG soft, and obtained14physiological constant.2, The measurement of modern Xinjiang uygur female pelvic obstetric physiological constant and diameter:12physiological diameters and2angles were measured:pelvic entrance diameter (136.70±7.23mm), posterior sagittal diameter (47.67±7.59mm), midpelvis transverse diameter (105.36±6.17mm), midpiece sagittal diameter (42.06±6.40mm), transverse outlet diameter (114.09±0.35mm), transverse outlet sagittal diameter (66.13±9.09mm), pelvic inlet anteroposterior diameter (113.52±7.88mm), the sacral shame inside diameter (124.10±9.87mm), midpelvis anteroposterior diameter (121.22±7.11mm), pelvic outlet anteroposterior diameter (111.27±8.72mm), pubic symphysis height (32.22±3.45mm), length of the sacrum (105.87±9.53mm) and pubic arch angle (90.49±8.44°), sacral camber length (131.73±10.31°).3, The measurement of modern Xinjiang uygur female morphological characteristics physiological constant of sacrum:In Uigur females,63cases (63.3%) as were the standard type,7cases of sacral had4sacral pass, including2cases of lumbar vertebra and sacral pore was sacralization completely,3cases of lumbar vertebra and sacral pore was sacralization uncompletely,2cases vertebra and sacral pore was lumbarization.10cases (10%) had5sacral pass,20cases (20%) had sacrococcygeal joint abnormalities. We measured the physiological constant of sacrum:length of the sacrum:(4pairs of standard sacral pore:106.6±12.0mm,4pairs of unstandard sacral pore:96.4±11.2mm, The sacrum and coccyx joint abnormalities:116.0±10.2mm). Camber of the sacrum(4pairs of the standard sacral pore:132.8±13.2°,4pairs of the nonstandard sacral pore:135.1±3.9°,5pairs of the sacral pore:134.7±3.7°, the sacrum and coccyx joint abnormalities:160.8±4.2°). The rest of the measurements can be found in the body.4ã€Modern characteristics of xinjiang uygur female pelvis type:In100cases of Xinjiang uygur female,42cases(42.0%) were gynecoid type,38cases(38.0%) were platypelloid type,15cases(15.0%) were anthhropoid type,5cases(5.0%) were android type. The gynecoid type and platypelloid type was the most common type.Third Section:Discussion1. We reconstructed100cases xinjiang uygur female pelvis successfully based CT original data, using the Mimics soft and digital3-D reconstruction technology. The pelive were flat, smooth, radian nature, and we can observe it in arbitrary rotation. We can also split the pelvic use the Geomagic software, such as the left and right side of the pelvis and sacrum. Three-dimensional measurement of pelvic was used Mimics and UG soft, and obtained14physiological constant. 2.We found that the coccyx upwarp and the sacrum and coccyx joint abnormalities in the xinjiang uygur female was relatively high, the pelvic has its own characteristics.3. In the pelvic morphology study, we found:The gynecoid type and platypelloid type was the most common type, the anthhropoid type was less and the android type was the least in the xinjiang uygur female.Part threeHan female pelvic of Xinjiang digital three-dimensional model reconstruction and Pelvic measurement [Objective]Xinjiang is a multi-ethnic gathering areas, to understand the Xinjiang region of normal Han female pelvic morphology and obstetric physiological constants of characteristics, we use three-dimensional digital reconstruction of digitized measurement technology successfully build on the100cases in the body normal Xinjiang Uygur female pelvis foundation100cases, using the same reconstruction parameters body Xinjiang normal Han female pelvis digitized three-dimensional reconstruction, and reconstruction of the a successful pelvic the obstetric physiological constant measurement, get the modern Xinjiang Han women of childbearing age pelvis obstetric physiological constant value clear pelvis fineanatomical characteristics and the obstetric physiological constant. To get Uighur and Han female pelvis morphological and physiological constants, we also extracted the the Xinjiang Han female pelvis sacrum parts morphological and physiological constant measurement.[materials and methods] 1.the research object the Han and Uighur child-bearing period women active100cases respectively.
