This valuable product is used in cases of calving paralysis which commonly cause knuckling-under of one, or sometimes both, hind legs. The BOS splint is simply applied to the back of the leg using the special adhesive elastic bandage included in the kit. The splint bottom should be at ground level. Generally application of the BOS splint will allow the animal normal mobility almost immediately after application. The small splint is suitable for Jersey or smaller Friesian cows, and the large splint for larger Friesian or Holstein cows and the x-large for very large Holstein. Leave the splint in place from 4-7 days, depending on the severity of the condition. In all cases the splint can be moulded somewhat to the individually required shape by use of a heat gun or hair dryer. The BOS splint can be reused with a new bandage. Dimension length o.a. Note: Administration of anti-inflammatories at initial splint application may also be beneficial. Consult your veterinarian.
