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.
Key words--- radiography; incomplete
fracture; wrist; ROC analysis
