A Case Series Of437Patients With Hand Injury

Objective: The study which provides reference for relevant prevention andtreatment in the future is not only aim to learn the distribution of related factors ofhand trauma and the relationship among factors, but also to analyze the factors ofprognosis of hand injury as well as its economic burden.Methods: Employing the retrospective study, we selected437cases of handinjury who occurred in2011and whose diagnosis accorded with definition of handinjury in Kaiyun Street branch of China-Japan union hospital of Jilin University andcollected the relevant information. The data was processed and analyzed by the SPSS17.0statistical software.Results:①general condition: the average age of the patients was36±23yearsold and the main part of the patients were in25~49years old. Male to female ratiowas3.97to1among the patients. The patients mainly were workers and accountedfor43.25%(189/437).The patients who were the most in the survey were the peoplegraduating from junior high schools or lower and accounted for40.05%(175/437).②condition of injury: the number of people injured middle finger were themost,which accounted for22.07%(162/734).The bone accounted for the highestproportion of wounded tissue, which is29.02%(177/610). The primary cause ofinjury was crush injury and the proportion of it was34.32%(150/437).The ratio ofopen injury which was more than closed wound was85.81%(375/437).The handwound almost occurred in the factory and the percentage was48.05%(210/437).Thedaily peak time when28.61%of cases occurred was from4p.m.to12p.m.and thewound mostly happened in Monday.13.50%of the cases which accounted for thehighest proportion of patients were injured in April. The majority of the patients（77.12%）saw a doctor within6hours, while patients（2.74%）who saw a doctorbetween12to23hours were the least.277cases (63.39%) were single site damagewhich was most frequently in the wound.224cases(51.26%) were the injury ofdominant hand in this study. Well-healed patients accounted for26.54%(116/437),who were the most.However, there was1.38%of the cases who were deprived offunction.50.34%of the patients paid more than RMB10000.③the injuredenvironment: There were differences in multiple-site damage and the wound category under various environments （p＜0.05）. The incidence of multiple-sitedamage(50.00%) in the farmland was the highest. The open injury was common in thefarmland and the ratio was100.00%.④the kind of wound: There were differences inoccupation about the kind of wound（p＜0.05）. The crush injury which accounted for50.26%(95/189) was a familiar kind of wound of workers, while twist injury thepercentage of which was48.81%(41/84)was popular in the group of farmer. Therewere also differences in multiple-site damage of people with different kinds of wound（p＜0.05）.The ratio(48.45%) of multiple-site damage of the people with twist injurywas the highest.⑤treatment effect: wound category， the kind of wound andmultiple-site damage were the factors of treatment effect. The effect was better in thepatients who were open injury,as well as people with single-site injury and patientswith twist injury.Conclusion:①The patients primarily were male in age group of25to49yearsold, workers as well as people graduating from junior high schools.②the number ofpeople injured middle finger were the most.The bone accounted for the highestproportion of wounded tissue. Crush injury, open injury and single-site injuryrespectively accounted for the highest proportion of the kind of wound, the injurysorts and multiple-site damage. The hand wound almost occurred in the factory. Thedaily peak time was from4p.m.to12p.m,and the wound mostly happened in Mondayas well as in April. The majority of the patients saw a doctor within6hours. Most ofthe patients were partly deprived of function and paid more than RMB10000.③There were differences in multiple-site damage and the wound category under thevarious environments. Meanwhile, there were differences in occupation about thekind of wound. Besides, there were also differences in multiple-site damage of peoplewith different kinds of wound.④Wound category， the kind of wound andmultiple-site damage were the factors of treatment effect.
