Status of Bone Allografting in Japan - Nation-Wide Survey of Bone Grafting Performed from 1995 through 1999.
We report the status of bone allografting in Japan on the basis of the information obtained through questionnaires performed by the Japanese Orthopaedic Association (JOA). JOA performed a nation-wide survey in 2000, in order to clarify the current status of musculoskeletal tissue grafting in the orthopaedic practices in Japan. Conducted period was for 5 years from 1995 to 1999. As the results of this survey, it had been clarified that 92,984 bone graftings, which included autografts, allografts and synthetic bone substitutes, were performed during conducted 5 years. While the allografts were used only in 3,212 cases (3%), autograftings were performed in 64,193 cases (69%), synthetic bone substitutes were used in 25,576 cases (28%) in this series. The proportion of the number of operations for use bone substitutes increased every year, whereas that autografting decreased. The proportion of the number of allografting remained almost unaltered. Of the 706 institutions which answered to have experiences of tissue grafting, only 193 (27%) performed allograft.Since Kitasato University Hospital Bone Bank was developed in 1971, we have applied to clinical while doing basic research for preserved bone allograft. When extensive bone graft is required, allograft is very useful. In Japan, however, allograft is not performed widely. The foundation of regional bone banks is expected to resolve this problem. Since excision of bone preparations from cadaver donors is not common, bone allografts are not supplied sufficiently at present. It is needed to develop a network connecting bone banks in Japan. The enlightenment activities to the ordinary people and medical institutions will also be required.
