Cervical orthoses is important for the postopereative treatment of the cervical disorder. A Newly designed cervical orthoses, N-type cervical orthoses, has been developed for 5 years. It is characteristic of the N-type cervical orthoses that it is supported by frontal, suboccipital region, mastoid process and thorax without supporting mandibula.The availability of the N-type cervical orthoses is as follows;1) Alignment can be changed at will by posterior adjustable dual hinge.2) It can be easily taken off because frontal solid cuff is inlaid design and truncal jacket is fixed by magic tape.3) It allows the patient to eat and talk easily because no mandibular support is necessary.4) It is lighter than other orthoses (700gr).As a result of measurement of stability with the N-type cervical orthoses by radiography and photography, range of motion was 13.2° in flexion and extension, 7.6°, in bending, 8.3° in rotation, and rate of control was, 77.4% in flexion, and extension 74.8% in bending and 87.1% in rotation.
