Characteristic of
Allogeneic
bone grafts
Safety:
Extensive tests for infectious diseases such as AIDS, Hepatitis B&C
and Syphilis are performed on all donors procured by SPTB. Each
donor is thoroughly evaluated using medical and social history
questions, medical records, blood test and culture results, physical
examinations and autopsy reports.
Special washing
technique ensures the bone marrow that carry pathogenic factors and
immunogenic been eliminated drastically. 15-25kGy
gamma
irradiation sterilization effectively eliminate almost
all micro-organisms in the
bone grafts and ensuring no
infection and diseases transmitting from bone allograft to recipient.
validity:
Deep-frozen/freeze-drying and irradiation techniques can
significantly reduces the immunogenic response of the bone
allograft. Its` excellent histocompatibility can be easily creeping substituted ; The
nature porous structure make it easy for osteoconduction; The preserving
endogenous BMP and other bioactive elements make it easy for osteoinduction ; natural biomechanical strength
meet the function reconstruction need.
Convenience:
The majority of the grafts are freeze-dried to a moisture
level of less than 6%
can be stored at
room temperature for up to three years.
In
operation room, disinfect
outer package, disclosing
three layers of plastic bag, taking out the allograft bone, rehydrating grafts 15 minutes
before usage.
Deep frozen bone grafts can be
processed and shaped according to the doctors¡¯ order form, air-expressing with special package;
The grafts should be stored in the -2
