Morcellised bone allograft in an in vitro model was used to test the tendency towards cup rotation using small or larger fragment sizes of an impacted graft bed and different fat contents. A cup cemented on an impacted graft bed of larger sized bone chips from the Howex bone mill containing natural marrow fat was loaded eccentrically until the cup rotated. This required 3450 N. The same chips impacted in the same way, but defatted with warm saline solution required 7000 N for rotation. The… CONTINUE READING
