Your question is bit confusing sir. It is not explaining clearly whether you need the biomaterial which are actually needed as  part of the fracture fixation technique or bone grafts etc.

Both will be helpful , many thanks for your answer

Simply the biomaterial should have good mechanical properties, biodegradability and biocompatibility, finally it should mimic the bone nature

Bio-compatibility (non antigenic and easy integration) , biodegradability and good bio mechanical strength are the requirements. It should also be biomimetic. As regards to the part of fixation techniques you can think of well fabricated cortical screws derived from cortical bone  which needs no removal and also bone plates made out of synthetic absorbable like polymers already in use in suture materials which should be fabricated in the way that the biodegrability should be slow till the bone healing is over. and later on it will be resorbed.
