Abstract:

BACKGROUND: Fractures around femoral prosthesis are common complications after total hip arthroplasty, and the incidence rate is increased continuously, therefore, the improvement of methods and technology for the treatment of fractures around femoral prosthesis has become a research topic.
OBJECTIVE: To explore the therapeutic effect of various internal fixations for treatment of fractures around femoral prosthesis after total hip arthroplasty, and to provide a theoretical reference information for the improvement of treatment technology as well as the improvement of the quality of life in patients.
METHODS: The factors and internal fixation of the fractures around prosthesis during and after total hip arthroplasty were analyzed through experimental data analysis, especially the clinical effects of shape memory alloy embracing fixcator and locking plate internal fixation for the treatment of fractures around femoral prosthesis after total hip arthroplasty; and the effects of different internal fixations for the treatment of fractures around femoral prosthesis after total hip arthroplasty were compared.
RESULTS AND CONCLUSION: The age, years, type of prosthesis and the stability of the prosthesis were the risk factors of fractures around femoral prosthesis after total hip arthroplasty, such as the fracture risk of uncemented prosthesis was higher than that of the bone cement prosthesis. For the choice of internal fixation method for the treatment of fractures around prosthesis after total hip arthroplasty, shape memory alloy embracing fixcator could not damage the cortical bone around the prosthesis, and has the advantages of fixed solid, simple operation, less invasive and fewer complications, and so on, while the locking compression plate combined with steel cable internal fixation has the advantages of less trauma, little blood interference on the fracture fragments and fixed solid. Two kinds of internal fixation can obtain better clinical therapeutic effect, but the therapeutic effect of locking compression plate internal. fixation is bet ter than that of the shape memory alloy embracing fixcator internal fixation.
