Influence of clinical information on the detection of wrist fractures in children.
The purpose of this investigation is to assess the importance of clinical information for the detection of non-displaced wrist fractures in children. Twenty non-displaced fractures of the distal radius in children younger than 15 years of age and twenty age-matched controls were evaluated by five blinded observers before and after giving clinical data, and a receiver operating characteristic (ROC) analysis using a continuous rating scale with a line-marking method was performed. The detection of the fractures was significantly improved with clinical information, and the main reason for this was an increase in true positive fraction. Availability of adequate clinical data should be emphasized for interpreting radiography.
