Follow-up Studies of Treatment of Cervical Spondylosis

Of questionnaires which were sent to the patients of cervical radiculo- and/or myelopathy treated in this department during 1958-1970, 63 were completed and returned, 25 of these returned to our clinic for examination.The results were as follows;1) Nearly same results were obtained in the patients of radiculopathy both treated nonoperatively and with anterior spine fusion. Indication of the operative treatment should be strictly limited just to the patients complained severe and recurrent symptoms.2) In the series of cervical myelopathy who were treated non-operatively 4 cases were improved, 4 unchanged and 4 worse in 9 years. Of 8 cases who were undergone anterior spine fusion 4 were exellent and 3 improved.In the series of laminectomy of 8 cases 4 were improved, but 2 unchanged and 2 worse. These cases had revealed primarily severe cord lesion and 3 cases could not walk without support before operation. The cases of poor results had complained more than 3 years of history of myelopathy.
