A limb immobilizer device is provided for bracing and immobilizing the limb of a wearer. The device comprises an elongated cuff having a substantially rectangular body that is adapted wrap around the limb of the wearer. A plurality of cuff straps extend across the opening of the cuff to secure the cuff into a tubular shape around the limb, while one or more elongated wraps extend from the ends of the cuff to secure the cuff in position along the wearer's limb. The elongated wraps encircle the elongated cuff and the wearer's limb several times to secure the cuff to the limb and thus prevent movement. The wraps are preferably elastic and in some embodiments are removably attached to the cuff. Additionally, the interior surface of the cuff may support one or more pockets therealong that are adapted to support thermal packs for additional limb treatment.
