This invention is an improved cervical collar (10) having an elongated neck encircling band (12), a chin support brace (14), a sternum and shoulder brace (15), and adjustment system secured to the sternum and shoulder brace (15), and the elongated neck encircling band (12) for adjusting the height of the sternum and shoulder brace (15) in relation to the elongated neck encircling band (12). The adjustment system is designed to lock the sternum and shoulder brace (15) in position preventing further extension of the sternum and shoulder brace (15) in relation to the elongated neck encircling band (12) as well as preventing retrograde movement of the sternum and shoulder brace (15) in relation to the neck encircling band (12). The collar also includes a positive alignment tracking system for maintaining the sternum and shoulder brace (15) in parallel alignment with the elongated neck encircling band (12) as the height of the sternum and shoulder brace (15) is adjusted.
