- The navicular bone (NB) showed a more osteoporotic structure in the upright foot than in the lower angle foot, suggesting a more unloaded NB appearance.
- The deep digital flexor tendon (DDFT) appeared more compact in the upright foot than in the lower angle foot, suggesting a more contracted DDFT appearance.
- Exposing the distal limb tissues of young horses to a balanced biomechanical loading regime should be aimed at reducing uneven locomotor tissue development in the distal limb, thus possibly preventing early retirement as a sports horse later in life.
Unevenness is an important feature of foot conformation and coincides with both kinetic and kinematic asymmetrical locomotor differences. It reportedly may lead to early retirement of elite horses from a warmblood population. The aim of this study was to evaluate the radiological consequences of an uneven feet conformation and on distal limb tissue development. In a retrospective study, the complete sets of good quality radiographs of both distal forelimbs were compared objectively for 121 “foot lame” horses that had been admitted for magnetic resonance imaging of one or both front feet (2003-2010). A chi-square test was used to test for significant radiometric differences between the upright and the lower angle foot (P < .05); 60% of the horses were unilaterally lame in the upright foot, whereas 40% were lame in the lower angle foot, which appeared to be a nonsignificant difference. In 84% of the horses, the navicular bone (NB) had a substantially more radiolucent, osteoporotic structure (P < .05). In 88% of the horses, the deep digital flexor tendon (DDFT) in the upright foot was significantly more radiodense and pronounced than in the lower angle foot (P < .05). The NB showed a significantly more osteoporotic structure as scored in the upright foot than in the lower angle foot, whereas the DDFT appeared was scored more compact in the upright foot than in the lower angle foot, suggesting less tension on the DDFT. In conclusion, radiological differences between uneven feet in foot lame horses seem to be related to differences in distal limb locomotor tissue development.
