Muhle staging system of cervical canal stenosis

Muhle staging system of cervical canal stenosis

• stage 0: physiological alignment of the cervical spine is seen

• stage 1: disc herniation or protrusion without cord impingement on flexion and extension

• stage 2: cervical spondylosis with anterior cord impingement on flexion and extension. No posterior cord encroachment or pincer effect is seen at this stage.

• stage 3: cervical spondylosis with restricted motion of the involved segment, anterior or posterior cord impingement and pincer effect

• stage 4: cervical spondylitic myelopathy, anterior and/or posterior cord impingement and pincer effect at one or multiple levels, adjacent to or away from the primarily involved segment.
