采用深低温冷冻辐照灭菌同种异体骨充填良性骨肿瘤和痛样病变手术刮除后骨腔７例。除１例巨大骨腔由于手术后引流不畅，积血感染外，其余均Ｉ期愈合。术后１月Ｘ线片显示新骨生长、３月后骨愈合良好。深冻同种异体骨与受体组织的相容性好，是较理想之异体储骨。 Sterilization of allogeneic bone-filled benign bone tumors and pain-like lesions was performed using cryogenic cryogenic irradiation to remove the posterior bone cavity in 7 cases. Except for 1 case of huge bone cavity due to poor drainage after surgery, blood infection, the rest healed. X-rays showed new bone growth at 1 month postoperatively and bones healed well after 3 months. The deep frozen allograft bone has good compatibility with the recipient tissue and is an ideal allograft bone.
