Fractures of the proximal phalanx are quite common, constituting 30% of all fractures, and appear mostly in young horses running on the race track. Most of them are fatigue fractures. The most typical are sagittal proximal fractures. Treatment by means of osteosynthesis give good results. However comminuted ones occur rarely but their treatment and prognosis is much worse. The attempts undertaken for their management do not always succeed. In this article the treatment of one case of comminuted proximal phalanx fractures by means of osteosynthesis using cortical 4.5 mm screws is presented. A very good result was attained evidenced by the return of the horse to its previous type of work (a return to the race track).
