Arthroscopic Removal of Apical and Abaxial Sesamoid Fracture Fragments in Five Horses

Five horses with apical and abaxial fractures of the proximal sesamoid bones were treated arthroscopically. Ipsilateral and contralateral triangulation were used to remove abaxial fragments; apical fragments were removed by ipsilateral triangulation. Excellent visibility of the fracture fragments was obtained with each method. Dissection and removal of fragments was accomplished with standard arthroscopic instruments, tendon-splitting knives, and curved scissors. Excellent functional and cosmetic results were achieved in all cases.
