Abstract:
BACKGROUND: Femoral intertrochanteric fractures are closely related to sex, age, geographical environment and race. But there is a lack of epidemiology studies on femoral intertrochanteric fractures in the Inner Mongolia Autonomous Region. OBJECTIVE: To investigate the epidemiological features of femoral intertrochanteric fractures in Hohhot. METHODS: The clinical data of 1638 patients with femoral intertrochanteric fractures admitted in four hospitals of Hohhot from May 2008 to April 2015, including their age, gender, the etiology, time of injury, fracture types, were collected and reviewed retrospectively, and the distribution of the epidemiological characteristics were described. RESULTS AND CONCLUSION: Patients aged 70-79 years accounted for 27.35%, which was the highest in all groups. The overall proportion of older patients was up to 61.17%, among whom, the number of patients with the age of 75-89 years (33.82%) was the highest, and the number of children was the lowest (6.53%). The number of male patients was higher than that of female patients before the age of 50 years, and there was a small peak incidence in age of 10-19 years, but the number of female patients was more than that of male patients after 50 years (P < 0.05). Falling down became the leading cause of femoral intertrochanteric injury, accounting for 50.16% (P < 0.05); in addition, traffic and high falling injuries were also the major injury causes in male patients. The highest incidence of femoral intertrochanteric fractures occurred in winter (36.75%), while the lowest incidence was found in spring (15.75%). The incidence of femoral intertrochanteric fractures showed the epidemic peak in November, while it was lowest in July. According to the Evans classification, type Ⅲ was the most common (35.23%), and the proportion of unstable fracture was significantly higher than that of stable fracture (63.74% vs. 36.26%, P < 0.05). 31-A2 fractures accounted for 57.02% in AO classification. To conclude, the distribution of patients with femoral intertrochanteric fractures in Hohhot exhibits certain epidemiological characteristics in the aspects of age, sex, etiology, time of injury, and fracture types.
