Distal Radius Of The Comparison Of The X-ray Imaging Measurement

Objectives:Preliminary discussion of computer software for distal radius radiographic measurement accuracy and feasibility.Methods:Selection of wangjing hospital radiology shot of the standard wrist joint normal digital X-ray30pieces, the experimenter himself use the wrist joint computer measuring software to have related measurement; From the above X-ray film1of randomly selected, And from Wangjing Hospital osteopathic graduate in30randomly selected, The30officers were using clinical scale measurement method and computer wrist measurement software measurement method on the1radiographic measurement, Each kind of method for the measurement of time. Measurement of main content:radius ulnar deviation, ulnar variance, wrist joint arc chord.Results:Computer wrist measurement software for radial longitudinal axis determination: The distal and slope to radial carpal articular surface distance was38.996+10.494mm, Proximal point to the radiocarpal joint surface distance of69.337+11.011mm; Computer wrist measurement software measurement value standard deviation, range, dispersion coefficients are measured values of small contest rule; Taking the measured value of the deviation from the mean absolute value of test analysis, radius ulnar deviation and wrist joint arc chord of the P value of less than0.05, with statistical significance; Ulnar variance P values greater than0.05, not statistically significant.Conclusions:People using computer wrist measurement software measurement numerical dispersion is small, the software has a good consistency and repeatability.
