| Objective：To study the epidemic characteristics of the distal femurfractures in adult in Orthopaedic Hospital of Hebei Province from2003to2012and investigate the epidemiological trend of distal femur fracture bycomparing the distribution features of distal femur fractures with special focuson sex, mean age, age groups and AO classification between2003to2007and2008to2012.Methods：The data of the distal femur fractures in adult treated between2003January to2012December in Orthopaedic Hospital of Hebei Provincewere collected through the PACS system and case reports checking system,and the epidemic characteristics and trends were analyzed. Patients’date from2003to2008were defined as group A, and from2008to2012were defined asgroup B. All patients were divided into different groups according to age andgender (every10years, including16to20years group and over80yearsgroup).We comprise the distribution features with special focus on sex, meanage, age groups and AO classification between the two groups.Result：A total of1217cases (849for male and368for women) ofdistal femur fractures in adult were treated in Orthopaedic Hospital of HebeiProvince from2003to2012, accounting8.98%of the femoral fractures(13547cases) and0.96%of all fractures (126479cases) over the same period.The left and right ratio was1.37:1. The fractures mainly caused in age groupof31to40years, accounting for21.45%. Male were more than female before60years and less than female after60years. The most common AOclassification was33-A, with a rate of48.48%. Trend analysis showed thatdistal femur fractures in adult presented an downward trend, but no significant difference (P＞0.05) were found. We also found that cases of males were indecreasing trend during last ten years, with annual2.42%(P＜0.05) and casesof females showed a increased trend with annual5.59%(P＜0.05). The distalfemur fractures in adult have a relationship with seasons and occur morecommon in spring. A total of667cases of distal femur fracture in in group A,509cases in men (76.31%) and158cases in women (23.69%), the mean agewas38.6±15.6years; while there were550cases in group B,340cases inmen (61.82%) and210cases in women (38.18%), the mean age was46.7±18.3years. The sex ratio compared between this two groups has significantdifference (P＜0.05), there was a higher rate of men in group A and a higherrate of women in group B. There was a significant difference (P＜0.05) in themean age between the two groups, group B has a higher mean age than groupA. Compared the distribution of ages ratio contrast between the two groups,there was a significant difference (P＜0.05), the ratios of distribution aged16to50years in group A were higher than group B, while the ratios ofdistribution aged50years and over in group B were higher than group A.There was a significant difference in the distribution of AO classification ratiocontrast (P＜0.05), the ratio of type33-A in group A was higher than group B,while the ratios of type33-B and type33-C in group B were higher than groupA.Conclution: The distal femur fractures in adult in Orthopaedic Hospitalof Hebei Province mainly caused in the young and middle-aged people, withmale was more than female. The proportion of men to women of distal femurfracture was gradually decreased. Fractures occur mainly in young persons inmen with a younger aging, and in elder persons in women with a older aging.The number of extra-articular fractures of AO classification graduallydecreased while the number of intra-articular fractures gradually increased. |
