Transverse fractures of the proximal phalanx occur in all breeds in all activities. They are specifically associated with incomplete sagittal fractures of the proximal phalanx in racing breeds and Warmblood horses, and may go unnoticed on preoperative examination.
The picture shows a 3 year old Standardbred male who suffered a displaced transverse fracture of the proximal phalanx, 5 days after repair of the sagittal proximal phalanx fracture.
Clinical signs and imaging
Clinical signs are acute severe lameness with soft-tissue swelling of the pastern and possible axial deformity.
A complete radiographic series is required to properly evaluate the full extent of the fracture.
