Clinical investigation of proximal tibial fractures in children in the Third Hospital of Hebei Medical University from 2008 to 2012

Abstract

Objective To investigate the age, gender distribution characteristics and structure of proximal tibial fractures in children in the Third affiliated Hospital of Hebei Medical University in 5 years. Methods We retrospectively analyzed the clinical data of all patients with proximal tibial fracture who had been treated in the Third Hospital of Hebei Medical Universcty from January 2008 to December 2012. All the children were divided into four groups by age: <3, 3-6, 7-11, 12-16. The gender and AO/PCCF (Association of Internal Fixation /Pediatric Comprehensive Classification of Long Bone Fractures) classification of different groups were recorded and analyzed. Results A total of 8 987 patients of children fractures were diagnosed or treated by the third hospital of hebei medical university in five years, including 1 163 patients of tibiofibula fractures, 118 patients of proximal tibial fractures. Proximal tibial fractures in children were accounted for 1.3% (118/8 987) of all fractures in children and 10.1% (118/1 163) of the tibial and fibula fractures in children. There were 80 males (67.8%) and 38 females (32.2%). The constituent ratio of proximal tibial fracture in males was higher than that in females. The constituent ratio of fracture showed a higher trend with the increasing of age. The constituent ratio of proximal tibial fractures in 12-16 age group was 52.5%(62/118), which was significantly higher than that in other age groups (P<0.05). There were 78 patients (66.1%) of type 41t-E fracture in AO/PCCF classification. There were 45 patients (38.1%, 45/118) of type 41t-E/7 fracture which was the most frequent fracture type among type 41t-E fractures. There were 40 patients (33.9%, 40/118) of type 41t-M fracture. There were 17 patients (14.4%, 17/118) of type 41t-M/2 and 41t-M/7 fracture which was more frequent than other type among type 41t-M fractures. The age distribution had significant difference in 41t-E/7 and 41-M/2 (χ2=16.657, Hc=32.702, all P values <0.05). Conclusions There were more proximal tibial fractures in males than in females. In the 12-16 age group, type 41t-E and 41t-E/2 were the high-risk fracture types. Male and older children need more attention to prevent proximal tibial fractures.
