Evaluation of the proximal subchondral bone plate in the equine proximal phalanx: intra- and inter-observer agreement for thickness and sharpness

The aim of this study was to evaluate the intra- and inter-observer agreement in the evaluation of sharpness loss at the subchondral/trabecular bone interface of the proximal subchondral bone plate of the proximal phalanx, and lateromedial asymmetry of the proximal subchondral bone plate of the proximal phalanx, as indicators of SCB sclerosis. The present study demonstrated an overall moderate agreement for assessment of the SCB plate of P1 in 11 isolated limbs, suggesting that subjective radiographic evaluation may be of interest in clinical settings.
