Pelvic fractures, the most severe bone trauma, account for approximately 3% of all fractures. As they are caused by high-energy injuries, their rates of mortality and disability are high. Over the past two centuries, the treatment strategies for these fractures have evolved from conservative therapy to open reduction and plate fixation, then to closed reduction and percutaneous screw fixation, and recently to screw fixation assisted by artificial intelligence. In the past 40 years, constant progress has been made in the treatment of pelvic fractures. It is generally acknowledged that a personalized treatment plan should be formulated based on each patient's age, fracture type, comorbidities, functional requirements and other factors when an appropriate treatment mode is chosen. The primary aim of treatment is to accelerate functional recovery, decrease the rate of disability after injury, and improve the quality of daily life of the patient. This paper reviews the treatment history of pelvic fractures, discusses the advantages and disadvantages of current treatment options, and looks ahead to future prospects, aiming to offer valuable references for related clinical practice.

Objective:To study the origin traceability of anemarrhenae rhizoma from Bozhou and Hebei based on multi-element fingerprints technology , and establish a discrimination model .Methods:The contents of 48 elements were determined by using induc-tively coupled plasma mass spectrometry ( ICP-MS) for 44 samples of anemarrhenae rhizome from Bozhou and Hebei province .Princi-pal component analysis ( PCA) and orthogonal partial least squares discrimination analysis ( OPLS-DA) were applied in the data analy-sis to screen out the significant elements .And then Fisher linear discrimination analysis was used to determine the origin of anemarrhe-nae rhizoma and the discrimination models were developed .Results:Two discrimination models were developed by the discrimination a-nalysis of the whole model method with nine significant elements identified by PCA and OPLS -DA, and 100％correct classification and 95.5％cross validation were achieved by the models .Conclusion: It is a promising approach to classify the geographical origin of anemarrhenae rhizome based on multi-element fingerprints analysis combined with multivariate statistical analysis .The discrimination models are good enough to be applied in the origin traceability of anemarrhenae rhizome.
