Biological Reconstruction Using Liquid Nitrogen-Treated Tumor Bearing Bone
In general, a tumor prosthesis is used for reconstruction after removal of osteosarcoma. However, the durability of artificial materials becomes a problem in the long term, and many patients inevitably undergo revision due to loose or damaged prostheses. Moreover, preservation of articular surface is the key to maintain better limb function for long duration. Reconstruction of affected limbs using biological materials has been sought to overcome the aforementioned problems. In some countries, it is significantly difficult to obtain allograft as a biological reconstruction material because of socio-religious or cost problem. Thus, a biological reconstruction method has been developed in which the patient’s affected bone is treated and used for reconstruction. Especially in recycling treatment for affected autologous bone, liquid nitrogen treatment has several favorable characteristics. There is optimal morphological fit because the treated bone itself is one’s own, and bone strength is maintained after treatment. Satisfactory bone union and bone regeneration are expected to be achieved due to good osteoconduction and osteoinduction because proteins and enzymes are preserved in the bone.
