Proximal phalanx: Complete uniarticular fractures

Fracture characteristics

Complete uniarticular fractures originate from the mid-sagittal groove of the proximal phalanx, extend distally into the intramedullary canal and course through the medial or lateral cortex of the proximal phalanx, usually within the distal half of the proximal phalanx.

These fractures are most typically seen in racing breeds.

Complete uniarticular sagittal fracture

Physical exam 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.
