The equine foot is an anatomically complex structure, in which soft tissue attachments between the distal phalanx (DP) and the hoof capsule support the entire musculoskeletal system. Equine laminitis affects these soft tissues of the foot and commonly leads to its structural collapse. Radiography is commonly used to diagnose laminitis and guide treatment and therapy. Several measurements to assess the position of the DP in relation to the hoof capsule have been described. Many of those have not been fully validated and the soft tissues in the sole area have not been the focus of previous diagnostic imaging evaluations. Our objectives were to establish normal hoof wall and sole measurements for Digital Radiography (DR) and Magnetic Resonance Imaging (MRI), to correlate and compare DR measurements with those made on MR images, to compare DR measurements before and after barium application to the surface of the sole, and to evaluate inter- and intra-observer correlation. We also aimed to distinguish if the two soft tissue layers seen on DR correspond to the epidermal and dermal layers as suggested previously and if these structures can also be imaged in the sole region. Fifty cadaver front feet of 25 adult horses of various breeds were imaged with DR and a 3 Tesla MR and various measurements were performed. Normal DR and MRI measurements are presented and statistically different (P < 0.0001). However, the difference is small (< 2mm). Measurements with barium applied to the surface of the sole were consistently smaller, than measurements without barium on the sole (P < 0.0001). There was good overall inter- and intra-observer correlation between DR (0.98/0.98) and MR (0.99/0.99) measurements. MRI measurements of the deep/sublamellar dermis and interdigitating epidermal and dermal layer corresponded to the lucent soft tissue opaque band surrounding the DP on DR images. Our measurements not only support established measurements, but also offer new approaches to quantitatively assess the anatomy of the equine foot.
