Boiled and unboiled detached autogenous bone fragments--an experimental study
The Netherlands Journal of Surgery
|August 1, 1986
Summary
Boiling bone fragments for sterilization causes a temporary delay in healing but does not harm bone regeneration. This sterilization method is safe for contaminated bone fragments in clinical settings.
Area of Science:
- Orthopedic Surgery
- Biomaterials Science
- Veterinary Medicine
Background:
- Sterilization of bone grafts is crucial for preventing infection.
- Autologous bone grafts are ideal but limited in supply.
- Alternative sterilization methods for contaminated bone are needed.
Purpose of the Study:
- To evaluate the effect of boiling on bone fragment resorption and new bone formation.
- To assess the clinical relevance of boiling as a sterilization method for contaminated bone.
Main Methods:
- Canine model using standardized detached bone fragments.
- Comparison of boiled versus unboiled bone fragments.
- Radiological, histological, and microangiographic examinations at various time points.
Main Results:
- Boiled bone showed a 10-14 day delay in resorption and new bone formation initially.
- Differences in healing were not discernible after 12 weeks.
- Boiled bone grafts demonstrated delayed but normal resorption and new bone formation.
Conclusions:
- Boiling is a safe sterilization method for contaminated bone fragments.
- Sterilized bone shows a transient delay in healing, with no long-term adverse effects.
- Boiling offers a viable option for preparing bone grafts from contaminated sources.
