What is Particle size influence in an impaction bone grafting model. Comparison of fresh-frozen and freeze-dried allografts about?

## Background: Impaction bone grafting with large particles is considered as mechanically superior to smaller morsels. interest of freeze-dried irradiated bone for impaction bone grafting has been observed with small particles. influence of bone process on other particle sizes still needed to be assessed. ## Material and methods: Twenty-four osteoarthrotic femoral heads were used to prepare fresh-frozen and freeze-dried irradiated cancellous bone. each group was divided into four batches of different particle sizes, each batch containing 18 samples. the different particle sizes were obtained with a retsch cross beater mill sk 100, noviomagus rotating bone mills with two sizes of rasps and a luer bone rongeur. bone grafts were impacted in a contained cylinder. stiffness was monitored during impaction. ## Results: Freeze-dried irradiated grafts showed higher stiffness than fresh-frozen bone whatever the size of the particles. large particles obtained with the rongeur and the large rasp from the noviomagus bone mill were mechanically superior than small particles up to 30 impactions. ## Interpretation: Large particles offer better mechanical performance as a greater magnitude of force
