How can we improve detection of equine distal phalanx fractures radiographically?

Lateromedial (A), dorsoproximomedial-plantarodistolateral oblique (B), and plantaroproximomedial-dorsodistolateral oblique (C) radiographs and T1 medial parasagittal (D), T1 transverse (E) and STIR transverse (F) MRI images of the right hind foot of a 7-year-old event horse with moderate right hindlimb lameness of 1 weeks’ duration. A) Narrow fracture lines can be seen spanning the superimposed plantar processes of the distal phalanx in a slightly plantarproximo-dorsodistal direction; the fracture involves the plantar aspect of the articular margin of the distal phalanx. B) a poorly defined, faint radiolucent line is seen extending across the medial plantar process of the distal phalanx. C, The fracture line extends in a dorsoaxial-plantaroabaxial direction across the medial plantar process of the distal phalanx near the junction with the body of the bone. A small separate centre of ossification is present at the palmar aspect of the medial plantar process. D, Narrow hyperintense fracture line running through the medial plantar process in a palmaroproximal-dorsodistal direction with reduced signal in the surrounding trabecular bone. E, Narrow hyperintense fracture line running through the medial plantar process in a mediolateral direction with reduced signal in the surrounding trabecular bone. F, Hyperintense fracture line in the axial compact bone of the medial plantar process with markedly increased signal in the trabecular bone of the medial plantar process and plantaromedial aspect of the body of the distal phalanx
