The aim of this study was the adjustment of one of the radiogram’s bone structure digital analysis methods, used at present for people, in order to use it in the investigation of horses’ proximal phalanx structures. Research was conducted based on radiograms of the bone of the fetlock belonging to horses of two races: thoroughbreds and Arabian horses. The values of parameters essential for the spongy bone fetlock, such as: the number of radiological trabeculas on mm², the average volume of the trabecula in mm% and the thickness expressed as percentage of surface coated with trabeculas. Analyses were carried out of the differences of each of the parameters of the structure of the essence of the spongy bone fetlock with regards to the race and the sex. The number, the volume and the thickness of radiological trabeculas of horses of thoroughbreds do not show essential differences to those of Arabian horses. Essential differences of these features among mares and stallions among thoroughbreds were not observed either.
