An article for treatment of an injured leg of a horse includes front (2) and rear (4) pivotally attached parts. The two parts form a cavity for receiving the leg when in a closed position and allow the leg to be received or removed when in an open position. In a first embodiment, one portion of the rear part receives the hoof of the leg, and the hoof is captured between lower portions of the front and rear parts as the front part is rotated toward the closed position but before the closed position is reached. In a second embodiment, the hoof of the leg is received by the front part. The capturing of the hoof before the front and rear parts are brought into full engagement allows the injured leg to be placed in tension to set the leg before the leg is fully encased in the inner lining of the article.
