ABSTRACT
Objective To evaluate the clinical efficacy of our self-made minimally invasive pelvic channel instrument in the treatment of pelvic ring fracture-dislocation.Methods A retrospective study was conducted of the 35 patients who had been treated for pelvic ring fracture-dislocation from December 2015 to November 2017 and fully followed up at Department I of Orthopaedis,Beijing Chaoyang Emergency Rescue Center.They were 25 males and 10 females,aged from 20 to 73 years (average,41.3 years).According to the Tile classification for pelvic fractures,there were 26 cases of type B (type B1 in 8,type B2 in 12 and type B3 in 6) and 9 cases of type C(type C1 in 5,type C2 in 3 and type C3 in 1).Infix or anterior plate combined with percutaneous internal fixation with sacroiliac cannulated screws was used in 11 patients,sacroiliac triangle fixation combined with percutaneous internal fixation with anterior ring cannulated screws in 5 ones,and internal fixation with cannulated screws for anterior and posterior rings in 19 ones.All the channels were established using our self-made minimally invasive pelvic channel instrument for internal fixation with cannulated screws.The time for each screw placement and the number of X-ray projection were recorded.Postoperative reduction,pelvic function at the final follows-ups and complications were recorded.Results A total of 84 cannulated screws were inserted in the 35 patients.The time for each cannulated screw placement ranged from 5 to 13 minutes (average,8.1 minutes);the number of X-ray projection for each screw placement ranged from 7 to 15 times (average,10.3 times).Postoperative CT showed that all the cannulated screws were located in the preset channels.According to the Matta radiological criteria,postoperative reduction quality was excellent in 29,good in 4 and fair in 2,giving a good to excellent rate of 94.3％.The follow-up time for the 35 patients ranged from 6 to 15 months (average,12.3 months).At the final follow-ups,all the patients showed fine fracture union.There was no loosening or breakage of screws in all but one patient in whom one sacroiliac screw became loose 3 months after surgery.By the Majeed criteria,the pelvic function was excellent in 27 cases,good in 5,fair in 3 and poor in one,giving a good to excellent rate of 91.4％.Conclusion Our self-made minimally invasive pelvic channel instrument can be used to establish pelvic channels,leading to more accurate placement,shorter operative time and less X-ray projection.
ABSTRACT
Objective The aim of this study was to assess the risk factors and epidemiological characteristics of placental abruption (PA) in Hebei province.Methods A cross-sectional survey was conducted to collect data on 218 880 pregnant women who were hospitalized in 22 hospitals which were under a monitoring program,in Hebei province,from January 1,2013 to December 31,2016.Data regarding epidemiological characteristics as time distribution,population distribution and related risk factors of placental abruption were gathered and analyzed.Results In this cohort study,218 880 women were included,with 669 (0.31％) of the pregnant women having PA.The overall prevalence rates were higher in the South than in the north parts of the area and higher in more developed regional economic centers.The average age of women having the episode was (27.87 ± 4.50) years and presented “J” distribution on the prevalence of maternal age.Results from the multivariate regression analysis showed that the following factors were independently at risk for placental abruption:pregnancy the including hypertension (OR=1.65,95％CI:1.09-2.50),mild preeclampsia (OR=3.65,95％CI:2.40-5.56),severe preeclampsia (OR=4.72,95％CI:3.86-5.76) and anemia (OR=2.41,95％CI:2.05-2.83) which were all increased in pregnant women with PA compared with the normal female population without placental abruption.Conclusions Placental abruption seemed to be associated with a moderate increasing risk of age,and was seen higher in those population older than 35 or younger than 20 year-olds.It was suggested that appropriate inoculation programs should be taken in different regions,especially on high-risk groups.Health education on related disease was of great significance for improving the prenatal outcome.
ABSTRACT
Objective To analyze the correlation between age and pregnancy-induced hypertension (PIH) in pregnant women from Hebei province in 2016.Methods A retrospective analysis was conducted by using the clinical data of 64 909 pregnant women,delivering in 22 hospitals in Hebei in 2016.Descriptive statistics was used to describe the general data and pregnancy outcomes of pregnant women,andx2 test was used to compare the incidence of PIH in different age groups,and logistic regression analysis was used to analyze the risk factors for PIH.Results The incidence of PIH was lowest in 20-29 year old women,and increased obviously in those aged ＜20 and ＞35 years (P＜0.05),and the incidence was positively correlated with age.Logistic regression analysis showed that age,times of pregnancy,number of previous cesarean section and fetus number of current pregnancy were the risk factors for PIH (OR=1.293,1.153,1.307,3.607),while times of deliver and times of prenatal examination were the protective factors (OR=0.655,0.951).Conclusion Advanced age pregnancy and young age pregnancy would significantly increase the incidence of PIH.Prenatal care should be strengthened for pregnant women at risk for PIH.
