How to Remove Osteochondral Axial Fragments From the Proximopalmar or Proximoplantar Aspect of the Proximal Phalanx Using a Bipolar Radiofrequency Device

摘要

Osteochondral (OC) fragments of the plantaro-prox-imal aspect of the proximal phalanx are most frequently reported in Standardbred racehorses but are rarely encountered in Thoroughbred racehorses or Warmbloods. These fragments have been classified previously into three categories: Type 1: fragments originating from the palmar/plantar aspect of the proximal end of the first phalanx just medial or lateral to the sagittal ridge (axial). Type 2: fragments originating from the plantar/palmar aspect of the eminences of the proximal phalanx. Type 3: fragments originating from the base of the proximal sesamoid bones.
