Evaluation of platelet-rich plasma applied in the coronary band of healthy equine hooves.

Abstract

Platelet-rich plasma (PRP) is a widely used hemocomponent that holds great promise in equine medicine due to its feasible production and regenerative therapy potential. Its use has been considered as a treatment for chronic laminitis, mainly in terms of its analgesic properties and because it can induce growth in affected hooves. The aim of this study was to evaluate the effect on hoof growth attributable to PRP applied in the coronary band of clinically healthy horses by comparing the responses to PRP, saline, and trimming alone. After randomization, the forelimbs of 9 horses received specific treatment at intervals of 33 days and were trimmed, measured, and radiographed at the same time. Neither hoof growth nor hoof angles were different between the treatment groups at any time point. The application of PRP in the coronary band of horses may be a safe procedure; however, it had no effect on the growth or conformation of hooves in clinically healthy horses.
