A cervical thoracic orthosis includes a chest plate and a back plate for overlying a patient's chest and back, fastening means for securing in a fixed position around the patient's upper torso, an occipital support shaped to conform to the occipital region of the patient's head, an occipital support bar secured to the occipital support and fastened to the back plate a chin support shaped to conform to the chin and lower jaw region of the patient, and a chin support bar secured to the chin support and fastened to the chest plate. In one embodiment, the chin support is hinged to the chin support bar so the chin support can rotate to a desired angle at which the patient's head is held. Adjustable fasteners extending between the occipital support and the chin support are secured to hold the patient's head in the desired angular position. The occipital support bar extends vertically and is shaped to provide a rigid means of support conforming to the shape of the patient's upper cervical spine. The occipital support also includes a U-shaped lateral support bar extending around the occipital region of the patient's head to reinforce the occipital support and prevent rotation of the patient's head. The chest plate, back plate, occipital support and chin support are all made from a thin, semi-rigid shell lined with an inner layer of an open cell containing resilient foam. The shells bend to conform to anatomical contours.
