Is rotation the mode of failure in pertrochanteric fractures fixed with nails? Theoretical approach and illustrative cases

ConclusionExcessive rotation leading to eventual “cut-out” has not been adequately studied, and thus, available evidence is not sufficient to definitely prove this theoretical approach. As nailing is gradually overtaking extramedullary fixation as the treatment of choice, especially for comminuted pertrochanteric fractures which can be rotatio nally unstable, further research is warranted to improve our understanding of the pathogenetic mechanisms of failure.
