title: Focal increased radiopharmaceutical uptake in the dorsoproximal diaphyseal region of the equine proximal phalanx.
abstract: The aims of this study were to establish the frequency of occurrence, intensity and symmetry of focal increased radiopharmaceutical uptake in the dorsoproximal aspect of the diaphysis of the proximal phalanx; to determine if this focal increased radiopharmaceutical uptake was related to age, height, gender, breed, bodyweight, or discipline of the horse, and if there was any relationship with lameness. Scintigraphic images from 690 horses were analyzed subjectively and objectively. Age, breed, discipline, height, weight, gender, and lame limb(s) or reasons for presentation were recorded for all horses. Univariate and multivariable logistic regression was performed to identify associations between available variables and focal increased radiopharmaceutical uptake. Focal increased radiopharmaceutical uptake was present in 17% of forelimbs and 7% of hindlimbs. It occurred most frequently in the forelimbs of older, taller, and heavier warmblood and warmblood cross dressage horses, and the hindlimbs of older, taller, and heavier showjumpers and dressage horses. It was usually bilaterally symmetrical and was not associated with lameness.
