New Philadelphia Immobilizer Support Collar
The Philadelphia collar is a semi-rigid CO with a 2 - piece system of Plastizote foam. Plastic struts on the anterior and posterior sides are used for support. The upper portion of the orthosis supports the lower jaw and occiput, while the lower portion covers the upper thoracic region. The Philadelphia Collar are used to immobilize patients with cervical spondylosis or hyperextension of the cervical region. The splints are made from high - density polyethylene sheet, which is anatomically contoured and foam padded along the edge for greater comfort.
