title: Mechanical failure of single cannulated screw fixation of unstable slipped capital femoral epiphysis.
abstract: Slipped capital femoral epiphysis (SCFE) is a common hip condition in adolescents, most commonly treated with in-situ cannulated screw fixation. We report two cases of cannulated screw failure within the femoral neck following SCFE fixation. To our knowledge, this is the first reported case in the literature of cannulated screw failure within the femoral neck following in-situ screw fixation for unstable SCFE.
