应用深低温冷藏胎儿骨移植治疗肿瘤性骨缺损、骨不愈合及延迟愈合５１例，除２例病变复发外，未见明显的移植骨溶解吸收现象，平均骨愈合时间为４个月，患肢功能恢复满意，表明深低温冷冻可进一步使胎儿骨的抗原性降低到最低限度，移植后不出现明显的免疫排斥反应，并保持有较强的骨诱导性，从而加速了植骨区的愈合过程。
Application of deep cryogenic fetal bone transplantation in the treatment of tumorous bone defects, nonunion and delayed healing in 51 cases, in addition to two cases of disease recurrence, no significant graft osteolytic absorption, the average bone healing time of 4 months, limbs Functional recovery was satisfactory, indicating that cryogenic freezing can further reduce the antigenicity of the fetus bone to a minimum, no significant immune rejection after transplantation, and maintain a strong osteoinduction, thus accelerating the healing process of bone graft area .
