Cervical spondylosis causing vertebrobasilar insufficiency: a surgical treatment.

Although the most common aetiology of transient vertebrobasilar insufficiency is atherosclerosis, a similar syndrome may occasionally be produced by cervical osteophytes. The possibility of such a remedial lesion makes further investigation mandatory in such patients-especially if symptoms are associated with sudden movements of the head or neck. When vertebral compression results from osteophytes, it can be easily relieved by a minor modification of the usual anterior cervical fusion technique. This method has proved to be quite efficacious in two patients whose case histories are reported.

Thoracic spondylosis presenting with spastic paraparesis.

Spondylotic change of the spine is common in the cervical and lumbar regions and may present with compression of the spinal cord and nerve roots. Myelopathy due to degenerative disease in the thoracic spine is exceptional. Only a few cases have been reported in the literature and these reports have described disease in the lower four thoracic segments. We report a case of paraparesis caused by degenerative disease in the upper thoracic spine which has not previously been described.

Asymptomatic degenerative disk disease and spondylosis of the cervical spine: MR imaging.

Evidence on magnetic resonance (MR) images of disk degeneration and herniation, as well as of cord and root impingement, may be regarded either as normal, age-related changes or as causative of symptoms. Individuals referred for MR examinations of the larynx without symptoms referable to the cervical spine were studied retrospectively (35 patients) or prospectively (65 patients) over a 2-year period. With a solenoid surface coil, 5-mm-thick sections were acquired in sagittal, axial, and coronal planes with T1-weighted spin-echo pulsing sequences. Disk protrusion (herniation/bulge) was seen in five of 25 (20%) patients aged 45-54 and 24 of 42 (57%) patients older than 64 years of age. Posterolateral protrusions were seen in only nine of 100 patients and occurred with greatest frequency in patients over 64 years of age. In no patient was obliteration of the intraforaminal fat seen. Spinal cord impingement was observed in nine of 58 (16%) patients under 64 years of age, and in 11 of 42 (26%) patients over 64 years of age. Cord compression was observed in seven of 100 patients and occurred solely secondary to disk protrusion in all cases. The percentage of cord area reduction never exceeded 16% and averaged approximately 7%.

A comparison of the short-term effects of ibuprofen and diclofenac in spondylosis.

In this controlled, single-blind parallel group study, the effect of ibuprofen 1200 mg daily was compared with diclofenac 75 mg daily. Thirty patients entered the study, randomized into two groups, each group receiving one tablet three times daily for two weeks. A one-week wash-out period (i.e. a drug-free period during which only physiotherapy was given), preceded and followed the treatment on active drug. Assessments were made by the same clinician throughout who was unaware of the treatment of individual patients. Statistically significant improvement was shown by patients receiving ibuprofen for the degree of pain relief at rest and improvement was also shown for the degree of pain at rest and during exercise, for pain relief during exercise and for spinal flexion. Patients who received diclofenac showed statistically significant improvement for forward flexion, together with improvement for the degree of pain on exercise. Side-effects were very few.

Analysis of cervical spine curvature in patients with cervical spondylosis.

Computer-aided design techniques were used to analyze the degree of spinal curvature shown on cervical spine radiograms of 28 patients. On films standardized as to size, a geometrical chord was constructed from the 2nd to the 7th cervical vertebrae (C2 to C7), and an arc was drawn along the posterior margin of the vertebrae. The resulting area was used as an index of curvature, and the spinal canal diameter was measured. Severity of myelopathy as well as clinical improvement was related to the geometrical data. There was no clear correlation between severity of the preoperative myelopathy and degree of curvature. Severe myelopathy was seen in association with straight, lordotic, and hyperlordotic spines. Neck pain was most severe in patients with reversed cervical curvature. The degree of curvature, however, seems to relate to the postoperative clinical outcome. Patients with relatively normal curvature showed the greatest improvement in symptoms and signs. Postoperative magnetic resonance scanning confirms that posterior migration of the spinal cord after laminectomy may be inadequate to clear osteophytes in patients with straightened or reversed curvature of the cervical spine. Spinal geometry should be considered in the selection of the best surgical procedure and the extent of laminectomy for patients with spondylotic myelopathy. Significant abnormalities of spinal curvature may account for some instances of poor outcome after laminectomy.

Medical management of cervical spondylosis.

Medical management is often the initial management of cervical spondylitic syndromes, including radiculopathy, myelopathy, and neck pain. This includes pharmacological and rehabilitation treatment. Prospective studies comparing the efficacy of surgical versus medical management are lacking. The indications and efficacy of pharmacological and rehabilitative treatments are reviewed. The use of anti-inflammatory drugs, muscle relaxants, analgesics, antidepressants, anticonvulsants, steroids, facet joint ablation, and physical therapy are reviewed. A rationale for the medical management of acute neck pain, chronic neck pain, radiculopathy, and myelopathy is presented.
