Effects of aluminum hinged shoes on the structure of contracted feet in Thoroughbred yearlings.

Tanaka K, Hiraga A, Takahashi T, Kuwano A, Morrison SE - J Equine Sci (2015)

Bottom Line: We applied aluminum hinged shoes (AHSs) to the club foot-associated contracted feet of 11 Thoroughbred yearlings to examine the effects of the shoes on the shape of the hoof and third phalanx (P III).After 3 months of AHS use, the size of the affected hooves increased significantly, reaching the approximate size of the healthy contralateral hooves with respect to the maximum lateral width of the foot, the mean ratio of the bearing border width to the coronary band width, and the mean ratio of the solar surface width to the articular surface width.These results suggest that the AHSs corrected the contracted feet in these yearling horses.

Frontal macroscopic views (left columns) and corresponding dorsopalmar radiographic views (right columns) in a case of contracted foot (male, 13 months of age, left frontal foot).a, b) Before AHS application. The angles of the lateral and medial sides of the hoof wall and P III were approximately perpendicular to the ground. b, c) Foot after 3 months of AHS application. The angles of the lateral and medial sides of the hoof wall and P III were lower than those before AHS use.

The angles of the lateral and medial sides of the hoof wall and P III were approximately perpendicular to the ground. b, c) Foot after 3 months of AHS application. The angles of the lateral and medial sides of the hoof wall and P III were lower than those before AHS use.

Mentions: Before AHS application, we observed a significant difference in the maximum lateral width of the hoof between the contracted and control feet. In contrast, 3 months after AHS application, this difference was not significant. In addition, the B/C and S/A ratios of the contracted feet, which were significantly lower than those of the controls before AHS application, showed no significant difference compared with the controls after 3 months. These results suggest that the shape of the contracted foot gradually reached to that of the control foot during AHS application (Fig. 5Fig. 5.
