Complete dorsal plane biarticular fractures originate from the proximal articular surface of the middle of the proximal phalanx. They are often associated with pre-existing osteoarthritis of the fetlock joint.
They occur in all breeds, in all activities.
Clinical signs and imaging
Clinical signs are usually acute severe lameness with an effusion of the fetlock joint and soft-tissue swelling.
A complete radiographic series is required to properly evaluate the full extent of the fracture and to rule out comminuted fractures and/or additional injuries.
