Clinical epidemiology features of the acetabular fracture in patients with different ages / 中华骨科杂志

ABSTRACT

Objective To analyze the epidemiology,mechanisms of injury,type of fracture,clinical and radiological feature of acetabular fractures in patients aged 60 years and older.Methods Retrospectively analyzed the clinical data of patients with acetabular fractures between Janurary 1990 and December 2013 in Orthopaedic Department of the First Affiliated Hospital of Soochow University.According to certain inclusion and exclusion criteria,a total of 637 patients (637 hips) with acetabular fractures were included in the study.The patients were divided into 2 group acetabular fractures in elderly (≥60 years) and acetabular fractures in younger patients (＜ 60 years).Analysis of mechanism of injury,fracture pattern,the annual incidence of fracture,radiological features,associated injuries.Results 133 patients were ≥60 years and the remaining 504 were ＜ 60 years.We identified a significant increase in the incidence of elderly with acetabular fractures between 1990 and 2013 (6.7％ in 1990 vs.40.0％ in 2013).The incidence of associated injuries were significant lower in the elderly than younger (27.1％ vs.48.8％).The most common mechanism of injury in the elderly was a fall (36.1％),but this accounted for only 0.2％ of the younger with fractures.The incidence of anterior wall,anterior column,anterior and posterior hemitransverse were significant higher in the elderly than younger.The incidence of radiological features were significant higher in the elderly than younger,including quadrilateral plate fracture,Gull sign,anterior dislocation of hip,femoral head injury,comminuted posterior wall fracture and posterior wall marginal impaction,except posterior dislocation of hip which was significant lower in the elderly than younger.Conclusion There was an increasing trend of the proportion of elderly in acetabular fractures and the mean age of patients with fractures during the period of study.The older had a different incidence of associated injuries,mechanism of injury,fracture pattern,and radiological features compared with the younger.
