Abstract:
OBJECTIVES:The purpose of this study was to determine the accuracy and reproducibility of image intensifier
(fluoroscopic) measurements of gap and step-off displacements on the articular surface of the distal radius using a standard cadaver osteotomy fracture model.
METHODS:Fourteen orthopedic residents were randomly assigned using the fish bowl method to measure the gap and step-off displacements in cadaveric fluoroscopic images using a digital caliper. Each physician was randomly assigned the images where they examined the images twice and the average taken using a standard technique. The interobserver and intra-observer reliability were calculated using the intraclass correlation coefficient (ICC). Rank Sum test was used to evaluate the validity of measurements.
RESULTS:The results of the study showed that there was no significant difference between the cadaveric and
measured step-off and gap displacements. Intraclass correlation coefficient scores showed moderate (0.41) to perfect (1.0) agreement.
CONCLUSION:The study showed that fluoroscopy can aid in the interpretation of gap and step-off displacements in acute distal radius fractures.
