Proximal phalanx: Short incomplete fractures

Short incomplete fractures originate from the midsagittal groove of the proximal phalanx and extend no more than one third of the length of the proximal phalanx in the distal direction.

Short incomplete fractures of the proximal phalanx are typically seen in racing breeds and Warmblood horses. Clinical signs are usually acute severe lameness with or without an effusion of the fetlock joint.

In most cases, a dorsopalmar radiograph confirms the diagnosis. A complete radiographic series is required to properly evaluate the full extent of the fracture and to rule out additional injuries.
