Plausibility Model Femur Fractures Resulting From Stair Falls Among Children: An Injury
Published on Jan 1, 2013
ABSTRACT. Background. Stair falls are commonamong young children and are also common false histo-ries in cases of child abuse. When a child presents with afemur fracture and a stair-fall history, a judgment ofplausibility must be made. A lack of objective injury andbiomechanical data makes plausibility determinationmore difficult. Our objective was to characterize keyfeatures associated with femur fractures from reportedstair falls, to develop a model for assessing injury plau-sibility (IP). Methods. Children 2 to 36 months of age who pre-sented with a femur fracture from a reported stair fallwere studied prospectively. Detailed history recording,examinations, fracture characterization, and injury sceneanalyses were conducted, and biomechanical measuresassociated with injury prediction were calculated. Withour proposed IP model, all cases were then scored for thedetail of history, biomechanical compatibility of fracturemorphologic features, time to seeking care, and presenceof other injuries.
