Summary
Bacterial contamination in allograft bone was studied in 401 donors. Cadaveric donors had the highest contamination rates (35%), especially in hemipelves, highlighting the need for strict screening in bone banks.
Area of Science:
- Orthopedics
- Microbiology
- Transplantation
Background:
- Allograft bone is crucial for musculoskeletal reconstruction.
- Bacterial contamination poses a significant risk to allograft viability and patient safety.
- Understanding contamination rates across donor types is essential for effective screening protocols.
Purpose of the Study:
- To determine the incidence of bacterial contamination in retrieved allograft bone.
- To analyze contamination rates based on donor type (live, multiorgan, cadaveric) and bone type (hemipelvis, femur, tibia).
Main Methods:
- Retrospective analysis of bacterial contamination data from 401 allograft bone donors.
- Data collected between January 1987 and March 1996.
- Comparison of contamination rates across different donor categories and bone segments.
Main Results:
- Overall contamination rates varied by donor type: live donors (13%), multiorgan donors (24%), and cadaveric donors (35%).
- No significant difference in contamination by bone type was observed in multiorgan donors.
- Cadaveric donors showed a significantly higher contamination rate in hemipelves compared to femurs and tibias.
Conclusions:
- Cadaveric bone allografts present a higher risk of bacterial contamination.
- Hemipelvic allografts from cadaveric donors require particular attention for contamination control.
- Findings are critical for musculoskeletal banks relying solely on screening for contamination, especially those not using secondary irradiation.
