Posterolateral approach to ruptured median and paramedian cervical disk.

The trend toward anterior diskectomy for median and paramedian cervical disk rupture has tended to obscure progressive development of the posterolateral approach to these lesions. Modifications of surgical technique from the classic posterior approach have allowed direct access to these lesions, provided for satisfactory decompression of the spinal cord, especially when there is associated spondylosis, and avoided all of the disadvantages of anterior disk surgery. Of 28 patients operated on since 1950, 26 have had significant preoperative myelopathy or myeloradiculopathy. Two patients with obvious spinal cord compression and massive myelographic defects had no neurologic deficit. Improvement has been observed in every patient; 16 patients have had full recovery, and 8 others have had minor residual symptoms and asymptomatic signs. Although four patients have been lost to follow-up, they were all seen at least once after operation. No instance of increased deficit has been seen postoperatively, in contrast to the author's experience with spondylotic myelopathy. Postoperative contrast studies, which have now been performed on eight patients, confirm satisfactory excision of these lesions and decompression.

Evaluation of cervical spine surgery by postoperative myelography.

After spontaneous remission of nerve root compression, a myelographic defect may persist. Similarly, myelopathy may remain nonprogressive for long periods despite appreciable myelographic deformity. Although operation may arrest or improve the symptoms of cervical disc lesions and spondylosis, the ultimate confirmation that entrapped neural elements have been relieved permanently can only be provided by postoperative myelography. Preoperative and postoperative myelography documents the significant improvement that can be achieved by using posterolateral and posterior approaches to the cervical spine in patients with nerve root or spinal cord compression. The results in this group of patients were achieved with none of the disadvantages or complications of cervical spine fusion or of the interbody removal of cervical disc tissue, also leading to cervical fusion.

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.
