[FE modeling and analysis of the locking plate for proximal humerus fracture].

The FE model of proximal humeral locking plate was established and analyzed to provide academic support of the proximal humeral locking plate failure. The stress distributions of the locking plate were observed under the situations of the fracture area providing support and without support. In summary, this type of locking plate cannot afford the stress at 120 degrees abduction position under the situation of fracture area provides without support.

[Safety analysis and test advices of superconductive magnet].

Based on the current GB standard and IEC standard, some unique security risk points of the superconductive magnet were discussed and pointed, some security eigenvalue of widely used MRI were calculated, method and technology of the quench risk & protection were focused. Currently during the type test of superconductive MRI, the national standards and industry standards have not included items focus on superconductive magnet particularly, so this paper gives some recommended discussing and hopes to improve and enhance the future standard. Because superconductive MRI uses a large number of helium gas which is very short in China and if quenching, helium will evaporate quickly, so the helium recycling are also discussed.

[Design & development of orthopedics implants failure management system].

The orthopedics implants failure management system has been put forward according to the present status. The function of the system and typical failure case reasoning route also have been described. Furthermore, the analysis process has been presented by illustrating a typical failure case analysis.

[Comparison of domestic and international standards for orthopedic implants].

A great deal of comparisons on domestic standards for Orthopedic implants with ISO and ASTM standards have been presented, and some conclusions have been drawn: Domestic standards for orthopedic implants coincide with ISO and ASTM standards in the items of materials, geometry and classification. There are much bigger differences in some key performances of implants such as assembly, fatigue, wear and tear and so on. Some constructive ways have been suggested.

[Failure analysis of orthopedic implants].

The clinical failure factors of Orthopedic implants which happened recent years have been summarized. The main failure factors are quality of orthopedic implants itself, iatrogenic and patient-derived. The ways to preventive measures have been suggested.
