Fig. 7. Elastic bandage material should be applied along the top of the cast to prevent dirt, bedding, or debris from entering between the limb and the cast. Acryclic can be seen conforming around the cast edges.
Fig. 9. Two rolls of 3-inch fiberglass casting material are applied with the horse standing on the board and should encompass all of the foot except the toe.
glass casting material are applied with the horse standing on the board and should encompass all of the foot except for the toe (Fig. 9). It should extend proximally to encompass the proximal pastern. The proximal aspect of the cast should overlap only
half the width of the felt strip. It is important to fold the stockinette distally at some time during cast application so that it becomes incorporated into the casting material. The third roll of casting material should incorporate the toe and be applied with an assistant extending the limb cranially off of the board (Fig. 10).3 It is important to extend the limb cranially to keep the limb in extension as much as possible; pulling the hindlimb caudally to place the last roll of casting material will result in too much flexion of the distal limb. Flexing the limb while the casting material is not cured will result in wrin- kling; as a result, this will cause focal pressure to the limb under the cast and not allow proper hoof- pastern alignment. A figure-8 pattern may be used to adequately cover the toe and ground surface of the
Fig. 8. Once the stockinette and felt strip have been applied, the horse’s hind foot should be positioned so that the toe of the affected limb rests on a board that is at least 2 inches thick and 4 inches wide; the contralateral foot should be placed on a board with the same dimensions.
