Abstract

BACKGROUND:Periprosthetic
fracture 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.贵州省人民医院骨科胡如印

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.
