To evaluate inter- and intraobserver reliability of the assessment computed tomography features commonly used in identification classification medial coronoid process disease to assess variability percentage ulna sclerosis from single transverse images.Eight observers, on two occasions, reviewed 84 standardised images acquired at level apex process. Observers assessed: disease, fragmentation, osteophytes, grade delineation with normal bone defined using a sclerometer. Cohen's kappa intraclass correlation coefficient were calculated.Inter-observer agreement was fair moderate for changes consistent almost perfect osteophyte detection. Agreement poor grading. Percentage measured sclerometer had agreement.These findings suggest that subjective is less repeatable than more quantitative methods.
