Cervical spondylosis. Prognostic value of preoperative signs and symptoms

One hundred and forty-one patients with cervical spondylosis were studied, looking for a possible prognostic value in preoperative signs and symptoms. Duration of symptoms lasting from one month to five years until surgical treatment and spinal fluid protein level had no prognostic value in these patients. In those with radiculopathy, the degree of upper limb pareses, muscle atrophy, absent or diminished reflexes, sensory involvement, number of myelographic defects and age had prognostic value. In those with myelopathy, the degree of lower limbs pareses and spasticity, sensory involvement, number of myelographic defects and age had prognostic value. Surgery is a definite method of treatment for patients with progressive signs and symptoms due to cervical spondylosis; some of the preoperative signs and symptoms are valuable in establishing their prognosis.
