The Yale cervical orthosis is a lightweight polyethylene foam Philadelphia collar with molded fiberglass extensions over the thorax. This orthosis was studied on 17 normal subjects in the extremes of the ranges of flexion, extension, rotation, and lateral bending using roentgenograms and axial photographs to assess how effectively it limited motion of the neck. Overall, it satisfactorily controlled cervical motion and was similar to the most effective rigid cervical orthoses. Flexion and extension ranges were compared at different segmental levels of the spine. The Yale orthosis was most successful in restricting flexion in the area of the middle and lower cervical spine and was acceptable in controlling extension range. The orthosis was least effective in controlling motion in the upper spine, particularly at the atlantoaxial articulation. The Yale orthosis is recommended for postsurgical protection of the middle and lower cervical spine and in select situations of spinal instability, but it is not recommended for control of odontoid fractures or atlantoaxial subluxation.
耶鲁颈椎矫形器是一种轻质聚乙烯泡沫费城颈托，在胸部有模压玻璃纤维延伸部分。使用X线片和轴向照片，对17名正常受试者在屈伸、旋转和侧屈范围的极限状态下进行了该矫形器的研究，以评估其限制颈部运动的效果。总体而言，它能令人满意地控制颈椎运动，与最有效的刚性颈椎矫形器相似。在脊柱的不同节段水平比较了屈伸范围。耶鲁矫形器在限制中下颈椎区域的屈曲方面最为成功，在控制伸展范围方面也可接受。该矫形器在上脊柱控制运动方面效果最差，尤其是在寰枢关节处。推荐耶鲁矫形器用于中下颈椎术后保护以及某些脊柱不稳定的情况，但不推荐用于控制齿状突骨折或寰枢椎半脱位。
