Proximal phalanx: Dorsal complete biarticular fractures

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 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.
