Abstract:
Objective:To analyze the clinical characteristics of patients with femoral neck fracture in Tianjin Hospital.Methods:Data of femoral neck fracture patients discharged from Tianjin Hospital from January 1, 2016 to December 31, 2017 were retrospectively analyzed. The gender, age, fracture type, injury mechanism and treatment method were collected.Results:Total of 2,150 eligible patients including 736 males and 1414 females were selected. There were significant differences in the gender distribution in different age groups ( χ2=91.63, P<0.001). Among young patients, males were more than females, while among middle-aged and elderly patients, females were more than males. The main type of fracture was displaced type (75.56%, 1,646/2,150), the displaced rate was the lowest in young patients (55.17%, 64/116), while it was the highest in old patients (81.91%, 1,159/1,415). The main injury mechanism of the three age groups were falls [young 61.21% (71/116), middle 80.29% (497/619), eldly 91.24% (1,291/1,415)]. There was a significant difference in the treatment methods between different age groups ( χ2=1,057.11, P<0.001). The main treatment method for young and middle-aged patients was internal fixation, no matter whether the fracture was displaced or not. The proportion of undisplaced patients with internal fixation (86.22%, 169/196) was higher than that of displaced patients with internal fixation (62.88%, 266/423) in middle-aged group ( χ2=34.93, P<0.001). In the elderly, more patients used internal fixation in undisplaced group, while more patients used hemiarthroplasty in displaced group. The age of old femoral neck fracture (median age was 74) was older than that of fresh fracture (median age was 70) ( Z=-2.777, P=0.005). And the displaced rate of patients with old femoral neck fracture (92.41%, 73/79) was higher than that of the fresh ones (75.95%, 1,573/2,071)( χ2=11.48, P=0.001). The patients with old femoral neck fracture usually adopt total hip replacement, while the proportion of three kinds of operation (internal fixation, hemiarthroplasty, total hip replacement) were similar among the fresh ones, and the internal fixation was the most. Conclusion:Femoral neck fracture is the most common in elderly women. The patients with displaced fracture are more than that with undisplaced fracture. Falling is the main injury mechanism in both young and old people. Internal fixation is commonly used in young and middle-aged patients, while arthroplasty is often used in elderly patients.
