Abstract: This research project presents a study of the fixation of screws in augmented and non-augmented cancellous bone at a microscopic scale.It is estimated that somewhere close to one million screws are failing each year.Therefore, the aim is to identify the key parameters affecting screw pull-out in order to improve screw fixation in cancellous bone, and hence screw design.The background for this study comes from work by Stryker, comparing screw pull-out from augmented and non-augmented cancellous bone, where a few cases of screw pull-out gave better results without bone augmentation.This is contrary to most evidence and the hypothesis to explain these results is that the screw pull-out from cancellous bone could be strongly affected by the cancellous bone micro architecture.I would like to mention some of the people who helped me to survive this
