| Background: The data of human fractures treated between 2011 January to 2013 August at hebei medical university third hospital were collected to investigate the epidemiological features of ulna and radius fractures in the extremely weather in Hebei Province of Shijiazhuang area as a reference for prevention.Methods: The data of human fractures treated between 2011 January to 2013 August at hebei medical university third hospital were collected through the PACS system and case reports checking system. This retrospective analysis was performed at Shijiazhuang area, ulna and radius fractures and extremelyly weather were selected With the exception of chronic fractures or pathological fractures or periprosthetic fractures. The patients’ hospital number and X-ray number and check up date and Patient information which included gender, age, fracture type, AO/OTA, Colles fractures and Smith fractures were collected. For fracture patients fuzzy or incomplete information or missing information, we according to the patients’ hospital number and X-ray number to maximize the chance that patient information accuracy and completeness from case reports checking system. Relevant reviewers were trained to classify the fractures, including AO/OTA and Colles fractures and Smith fractures. If any disagreement was encountered, a discussion was made until a consent was reached. All data and and information of extremelyly weather into Excel 2007 to delete duplicates. Ulna and radius fractures were selected and distributed into two groups, the data in the extremelyly weather were classified as group A, while the data in the other weather were designed to group B. All the data were calculated and analyzed by SPSS 19.0 package to comparison and analysis was done to both groups in the extremely weather. Measurement data using ±s and both of patient’s age comparison by Independent-Samples T Test, P-value < 0.05 was considered statistically significant. Both of patient’s gender and age distribution comparison by x2 tests, P-value < 0.05 was considered statistically significant.Results: A total of 24997 fractures were selected with 5690 in 237 day in the extremelyly weather and 19307 in 737 day in the other weather. A total of 3944 ulna and radius fractures were selected with 2097 left side and 1847 right side, with 2075 females and 1869 males, the total male/female ratio was 1: 0.9 and the average age were 40.2±22.6. The predominant age of the ulna and radius fractures was from 51 to 60 years, accounting for 18.2%(716/3944), and the age distribution showed that the peak range of ulna and radius fractures was 11~20 years old in man and 51~60 years old in women. The aged over 50 distributions showed that the proportion of females in ulna and radius fractures was higher than males, and the high-risk type of fracture was distal ulna and radius fractures. A total of 1505 Colles fractures were selected, accounting for 38.2%(1505/3944) of the ulna and radius fractures. A total of 187 Smith fractures were selected, accounting for 4.7%(187/3944) of the ulna and radius fractures. A total of 971 ulna and radius fractures were selected in the extremely weather in group A with 487 females and 484 males, the total male/female ratio was 1:1.0, and the average age were 41.5±21.8. In the extremely weather the predominant age of the ulna and radius fractures was from 51 to 60 years, accounting for 20.6%(200/971), and the age distribution showed that the peak range of ulna and radius fractures is 21~30 years old in man and 51~60 years old in women. In the extremely weather the aged over 50 distribution showed that the proportion of females in ulna and radius fractures was higher than males, and the high-risk type of fracture was distal ulna and radius fractures. A total of 367 Colles fractures were selected in the extremely weather, accounting for 37.8%(367/971) of the ulna and radius fractures. A total of 43 Smith fractures were selected in the extremely weather, accounting for 4.4%(43/971) of the ulna and radius fractures. The ulna and radius fractures A total of 2973 ulna and radius fractures were selected in the other weather in group B with 1382 females and 1591 males, the total male/female ratio was 1:0.9, and the average age were 39.8±22.8.In the other weather the predominant age of the ulna and radius fractures was from 51 to 60 years, accounting for 17.4%(516/2973), and the age distribution showed that the peak range of ulna and radius fractures is 11~20 years old in man and 51~60 years old in woman. In the other weather the aged over 50 distribution showed that the proportion of females in ulna and radius fractures was higher than males, and the high-risk type of fracture was distal ulna and radius fractures. A total of 1138 Colles fractures were selected in the other weather, accounting for 38.3%(1138/2973) of the ulna and radius fractures. A total of 144 Smith fractures were selected in the other weather, accounting for 4.8%(144/2973) of the ulna and radius fractures. There were 971 cases in group A and 2973 cases in group B, respectively accounting for 17.1%(971/5690) and 15.4%(2973/19307) of all the ulna and radius fractures in each group at the same time, giving a significant difference between groups(x2=9.185, P<0.01). The proportion of females in group A(59.2%) was higher than that in group B(56.5%), giving a significant difference between groups(x2=3.953, P<0.05). The average age were 68.8±16.5 in group A and 64.9±18.2 in group B(t=-2.144, P<0.05). The fracture type ratio compared between A and B type had no significant difference(P<0.05), and the Smith fractures ratio compared between A and B type had no significant difference(x2=0.037, P<0.05). The Colles fractures ratio compared between A and B type had significant difference(x2=8.398, P<0.05).Conclusion: The current investigation about ulna and radius fractures in the extremely weather in Hebei Province of Shijiazhuang area from 2011 January through 2013 August were characterized by the peak age of ulna and radius fractures was 21~30 years old in man and 51~60 years old in women, the ulna and radius fractures and Colles fractures patients has significantly increased, the women and elderly patients has significantly increased. |
