- Bone allograft is sterilised by gamma irradiation and stored at -80°C for use within 5 years, or by freeze-drying method and stored for long-term use
Common conditions requiring bone transplant
-
Bone fusion – donated bone can stimulate bone living cells to make bone grow and connect together (e.g. metal implantation for patients with scoliosis)
-
Bone defect restoration – donated bone can restore bone tissue defects (e.g. after benign tumour resection or artificial joint replacement)
-
Bone defect reconstruction – donated bone can reconstruct and fix bone defects (e.g. after bone resection due to malignant tumour)
