Abstract：Objective To investigate the epidemiological features and trends of adult proximal tibia fractures.Methods The data of patients with proximal tibia fractures between 2003 and 2012 at the Orthopaedics Department of the Third Affiliated Hospital of Hebei Medical University were collected and analyzed through the PACS system and case reports checking system. The data between 2003 and 2007 were classified as group Ⅰ, while the data between 2008 and 2012 were classified as group Ⅱ. Statistical data included gender, age and fracture type and comparison analysis was done to both groups.Results A total of 107 648 adult fractures were selected with 18 432 tibia and fibula fractures and 3 655 proximal tibia fractures. The proximal tibia fractures accounted for 19.8%(3 665/18 432) of the tibia and fibula fractures and 3.4%(3 665/107 648) of the total fractures. There were 2 575 males (70.5%, 2 575/3 655) and the peak range of highest age distribution (27.5%) was 31-40 years old with 707 fractures. There were 1 080 females (29.5%, 1 080/3 655) and the peak range of highest age distribution (20.7%) was 41-50 years old with 224 fractures. According to the AO classification, there were 1 227 fractures in 41-A1 subtype with the highest proportion of 33.6%. A total of 1 651 intraarticular fractures with 1 150 males and 501 females and 2 004 extraarticular fractures with 1 425 males and 579 females were selected. There was no statistically significant difference in sex ratios(χ2=0.918, P>0.05). 1 909 cases and 1 746 cases were classified as group Ⅰ and Ⅱ respectively, accounting for 18.7%(1 909/10 234) and 21.3%(1 746/8 198) of the proximal tibia fractures(χ2=13.364, P＜0.01), 3.4%(1 909/55 423) and 3.3% (1 746/52 225)of the total(χ2=0.784, P>0.05). The sex ratios were 2.5∶1(1 371/538) and 2.2∶1(1 204/542) respectively (χ2 =3.583, P>0.05) and the proportion of fractures older than 60 were 8.4%(161/1 909) and 12.8%(224/1 746)(χ2=18.697, P＜0.01). The proportion of 41-B in group Ⅱ (39.5%, 690/1 746) was higher than that in group Ⅰ (35.1%, 671/1 909) (χ2=7.45, P<0.01) and the proportion of 41-C in group Ⅱ (16.1%, 281/1 746) was lower than that in group Ⅰ (19.0%, 362/1 909) (χ2=5.177, P<0.05).Conlusions Adult proximal tibia fractures account for 19.8% of the tibia and fibula fractures and 3.4% of the total fractures. Males account for nearly 70% and are mostly seen between 31 to 40 years old. While females account for nearly 30% and are mostly seen between 41 to 50 years old. The proportion of fractures for patients who are older than 60 years increases 4.4%. There is no change in proportions of extraarticular and intraarticular fractures.
