[Cost analysis of a bone bank].

The costs of a bone-bank working in accordance with the guidelines of the german federal chamber of physicians are described. Establishing a bone-bank storing deep-frozen bone is not very expensive. The main costs are due to laboratory costs for excluding HIV, hepatitis, syphilis and bacterial contamination of bone grafts. In our experience with 206 bone grafts about 20% of them are to be discharged because of positive laboratory tests. The costs of each bone graft are DM 327. A second HIV-Test of the donor 3 months after explantation of a bone graft will cause rising of costs up to 47%. About 20-30% of bone graft donors will probably not carry out this test. In this case discharging of the bone graft is necessary.
