  • Title: [The selection of spongiosa donors for a bone bank].
    Author: Peters KM, Bruchhausen B, Leusch HG, Forst R.
    Journal: Dtsch Med Wochenschr; 1991 Dec 13; 116(50):1897-902. PubMed ID: 1748067.
    Abstract:
    A prospective trial was carried out in 156 unselected patients (41 men, mean age 67.5 years, 115 women, mean age 71.4 years) who had undergone total hip joint replacement because of degenerative or inflammatory arthritis or fracture of the neck of the femur. The excised femoral heads were subjected to three-stage bone bank screening so as to ascertain how many of them would pass the clinical, biochemical and microbiological exclusion criteria. Only 26 out of 156 femoral heads (17%) proved to be acceptable for the bone bank. Ninety patients (58%) were excluded on clinical grounds such as old age (over 80 years), malignant neoplasms, rheumatoid arthritis, previous intraarticular injections or long-term steroid medication. Positive hepatitis serology excluded 19%, and raised preoperative neopterin concentration excluded 25%, though three months postoperatively this was confirmed in only 2%. Routine neopterin assay seems to be a useful step towards improved bone bank screening, since neopterin concentration is clearly increased in recent virus infections such as HIV. Bacterial contamination was of no practical importance. Because of the low proportion of femoral heads passed as suitable for the bone bank, the existing exclusion criteria will have to be critically scrutinized, and alternative procedures for harvesting bone safe for transplantation (freeze drying, autoclaving, irradiation) will have to be employed.
