ABSTRACT
Objective To compare and analyze the epidemiological features of fractures at the base of the first metacarpal bone between East and West China.Methods We retrospectively analyzed the clinical data of the patients with fracture at the base of the first metacarpal bone who had been treated from January 2010 to December 2011 in 63 hospitals in the east and west areas of China.The data from 35 hospitals in East China were classified as group A while the data from 28 hospitals in West China as group B.The analytic items included gender,age,age distribution and fracture classification.Results A total of 890 cases were collected.The total male/female ratio was 4.56∶ 1.The youth accounted for the highest proportion and the high-risk type of fracture was type Ⅲ (44.49％,396/890).The male/female ratio was 4.59∶1 in group A of 621 patients and 4.49∶1 in group B of 269 patients,showing no statistic between-group difference (P ＞ 0.05).The median age in group A was 39 years,significantly older than that in group B (35 years) (Z =-3.687,P ＜ 0.001).In both groups,the youth accounted for the highest proportion and there were more right-side fractures than left-side ones.Group A had a significantly lower proportion of the youth and a significantly higher proportion of the middle-aged than group B (P ＜ 0.05),but there was no statistic difference in proportions of the children and the aged (P ＞ 0.05).Type Ⅲ was the high-risk type in both groups;group A had significantly more fractures of type Ⅰ and significantly fewer fractures of type Ⅱ than group B (P ＜ 0.05),but there was no statistic difference in proportions of type Ⅲ and type Ⅳ between the 2 groups (P ＞ 0.05).Conclusions Fractures at the base of the first metacarpal bone mostly occurred in the young males.There were more fractures at the right side than at the left side.The most frequent type was type Ⅲ.The proportion of type Ⅰ fractures in East China was higher than in West China while the proportion of type Ⅱ fractures in East China lower than in West China.
ABSTRACT
Objective To compare and analyze the epidemiological features of Colles fractures between Eastern and Western China from 2010 to 2011.Methods The data of patients with Colles fracture treated from January 2010 to December 2011 in 63 hospitals in Eastern and Western China were analyzed retrospectively.The patients from the 35 hospitals in Eastern China were defined as group A and those from the 28 hospitals in Western China as group B.The 2 groups were analyzed and compared in terms of gender,age and laterality.Results A total of 9,255 Colles fractures were collected.The total male/female ratio was 0.82:1.Their ages ranged from 1 to 110 years,with a median age of 51 years.The Colles fractures predominated in an age range from 51 to 60 years.There were 5,006 left sides and 4,249 right sides.There were 5,639 Colles fractures in group A,accounted for 2.55％ of the total body fractures and 22.09％ of the distal ultra-radius fractures.There were 3,616 Colles fractures in group B,accounted for 3.98％ of the total body fractures and 37.55％ of the distal ultra-radius fractures.The male/female ratio was 0.72:1 in group A and 0.99:1 in group B.The median age was 54 years (from 1 to 110 years) for group A and 45 years (from 1 to 99 years) for group B.There were significant differences between the 2 groups in all the above items (P ＜0.05).The largest proportion of age group was from 51 to 60 years and the smallest proportion of age group was ≥81 years for both groups.The proportions of age groups from 1 to 10 years,from 51 to 60 years,from 61 to 70 years,from 71 to 80 years and ≥81 years in group A were larger than in group B while those from 11 to 20 years,from 21 to 30 years,from 31 to 40 years and from 41 to 50 years in group A were smaller than in group B.There were significant differences between the 2 groups in all the proportions of age group (P ＜0.05).The Colles fractures predominated on the left side in both groups,showing no significant difference between the 2 groups (P ＞ 0.05).Conclusions The Colles fractures from 2010 to 2011 predominated in the elderly and female patients in China.The proportions of Colles fractures in all body fractures and distal ultra-radius fractures in Eastern China were lower than those in Western China.There were significant differences in gender and age proportions between the 2 areas.Eastern China had a larger proportion of female patients and a higher median age than Western China.

ABSTRACT
Objective To investigate the epidemiological features and trends of adult fractures at the base of the first metacarpal bone in The Third Mfiliated Hospital to Hebei Medical University from 2003 through 2012.Methods The data of human fractures treated between January 2003 to December 2012 at our hospital were collected through the PACS system and case reports checking system.Adult fractures at the base of the first metacarpal bone were included in the present study and assigned into 2 groups,group A containing the data between 2003 and 2007 and group B the data between 2008 and 2012.Comparison and analysis was done with analytic items of gender,age and fracture type.Results A total of 378 adult fractures at the base of the first metacarpal bone were included,accounting for 1.92％ of hand fractures and 0.35％ of the total adult fractures at the same period.The fractures involved 311 males (82.28％) and 67 females (17.72％).The youth group had 254 fractures with the highest constituent ratio (67.20％).The right side was involved in 286 cases (75.66％) and the left side in 92 (24.34％).There were 198 cases of extra-articular fracture with the highest constituent ratio (52.38％).Group A had 200 fractures,a male to female ratio of 6.14∶ 1,a median age of 34 years,the highest constituent ratio in youth (73.50％) and in type A1 fractures (53.50％);group B had 178 fractures,a male to female ratio of 3.56∶ 1,a median age of 40 years,the highest constituent ratio in youth (60.11％) and in type A1 fractures (51.12％).Compared with group A,group B had a higher constituent ratio of females,older ages,a higher constituent ratio of elderly patients,a lower constituent ratio of youth,and a lower constituent ratio of type C1 fractures.All these differences between the 2 groups were statistically significant (P ＜ 0.05).Conclusions During the 10 year,the adult fractures at the base of the first metacarpal bone accounted for 1.92％ of hand fractures and 0.35％ of the total adult fractures at the same period.The fractures occurred mostly in men and in the age range of 16 to 44 years.About 3/4 of them occurred on the right side.Compared with the first 5 years,the latter 5 years witnessed increasing trends of female and elderly patients and decreasing trends of young patients and type C1 fractures.
ABSTRACT
Objective To investigate the epidemiological features and trends of humeral intercondylar fractures at our hospital from 2003 through 2012.Methods The clinical data were retrospectively analyzed of all the patients with humeral intercondylar fracture who had been treated between January 2003 and December 2012 at our institute.The patients' age,gender,fracture site and AO classification were documented.The data between 2003 and 2007 were classified as group A while the data between 2008 and 2012 as group B.The epidemiological characteristics during the 10 years concerning age,gender and fracture type were compared between the 2 groups.Results A total of 303 humeral intercondylar fractures were recorded,accounting for 5.29％ of the distal humeral fractures,3.39％ of the elbow fractures and 0.24％ of the total fractures at the same period.They involved 197 males and 106 females,with a male/female ratio of 1.86∶ 1.The high-risk age group was adolescent and middle-aged adults,accounting for 63.70％.The high-risk type was type 13-C2,accounting for 44.00％.There were 171 and 132 cases in group A and group B,accounting for 5.40％ and 5.17％ of the contemporary distal humeral fractures,3.72％ and 3.05％ of the contemporary elbow fractures,and 0.26％ and 0.22％ of all the contemporary fractures,respectively,showing no significant differences between the 2 groups(P ＞ 0.05).In groups A and B respectively,the male/female ratios were 1.44∶1 and 2.67∶ 1,the proportions of adolescents and the middle-aged 58.48％ and 70.45％,the proportions of type 13-C1 35.83％ and 18.10％,and the proportions of type 13-C3 14.17％ and 44.76％,showing significant differences between the 2 groups in all the above comparisons (P ＜ 0.05).Conclusion The humeral intercondylar fractures were common in the adolescent and middle-aged patients,with a male predominance (about twice more in males).Compared with the first five years,the latter 5 years witnessed increased proportions of males,adolescent and middle-aged patients,and type 13-C3 but a decreased proportion of type 13-C1.
ABSTRACT
Objective To compare the outcomes of homeopathic bidirectional-traction reduction device and traction table in surgical treatment of femoral intertrochanteric fractures.Methods A retrospective case control study was made on 94 cases of femoral intertrochanteric fractures treated from July 2015 to December 2015.There were 26 males and 68 females,aged 60-75 years.According to the Evans classification,the fractures were type Ⅱ in 24 cases,type Ⅲ in 32 and type Ⅳ in 38.Fifty-seven cases sustained chronic diseases.According to the random number table,the subjects were assigned to receive homeopathic bidirectional-traction reduction (homeopathic reduction group,48 cases) and traction table reduction (control group,46 cases).All fractures were fixed with proximal femoral nail antirotation.Operation time,reduction time,tluoroscopy time,blood loss and rate of closed reduced cases were recorded.Fracture union and rotation of the affected femur to the tibia were detected after operation.Functional outcome was evaluated using the Harris score at the final follow-up.Results All fractures were reduced closely in homeopathic reduction group,while 15 fractures in control group were reduced via a small-incision anterior approach.Operation time,reduction time and fluoroscopy time in homeopathic reduction group were (62.9 ± 12.1) min,(6.8 ± 1.5) min and (11.3 ± 5.6) s respectively,significantly less than the corresponding data in control group (all P ＜ 0.05).One month after operation,rotation of the affected femur to the tibia was (2.8 ± 1.2) ° in homeopathic reduction group,significantly less than that in control group [(11.5 ± 4.7) °] (P ＜ 0.05).Bone union was observed in all cases.At the final follow-up,Harris hip score was (92.6 ± 7.6)points in homeopathic reduction group,significantly higher than that in control group [(87.3 ± 6.5) points] (P ＜ 0.05).Conclusion For the elderly patients with intertrochanteric fractures,homeopathic bidirectional-traction device has advantages of high rate of closed reduction,shorter operation time,less radiological exposure and satisfactory function recovery of the affected hip joint.
