Randomized Controlled Trial Comparative Study Clinical Trial
The value of MR imaging in differentiating between hard and soft cervical disc disease: a comparison with intraoperative findings.
The aim of this study is to assess the accuracy of MRI alone in the differentiation of soft cervical disc protrusion from osteophytic compression in cervical disc disease. In a retrospective study, the MRI scans of 41 patients with cervical disc disease, who had previously undergone surgery, were presented to three independent observers, randomly on two different occasions, to identify the accuracy of the diagnosis of the presence of hard or soft disc or both as a cause of compression. The observers (two neurosurgeons and one neuroradiologist) were not involved with the treatment of the cases at any stage and were unaware of the surgical findings. ⋯ The sensitivity of diagnosis of a hard disc was high (87%) but specificity was low (44%), due to the overestimation of the presence of hard disc. There was a significantly higher incidence of hard disc in the elderly age group (76% over the fifth decade, P = 0.0073). It is concluded that MRI alone is not a very efficient diagnostic tool in distinguishing between hard and soft disc in the cervical disc disease.

Review
Is there a rational basis for post-surgical lifting restrictions? 2. Possible scientific approach.
Lifting restrictions postoperatively are quite common but there appears to be little scientific basis for them. Lifting restricitions are inhibitory in terms of return to work and may be a factor in chronicity. The mean changes in functional spinal motion unit (FSU) stiffness with in vitro or computer-simulated discectomies, facetectomies and laminectomies were reviewed from the literature. ⋯ The adjusted NIOSH guidelines provide a reasonable way to estimate weight restrictions and accomodations such as lifting aids. Such resitrictions should be as liberal as possible so as to facilitate, not prevent, return to work. Patients need more advice regarding lifting activities and clinicians should be more knowledgeable about the working conditions and constraints of a given workplace to effectively match the solution to the patient's condition.

Tuberculosis of the spine is probably one of the earliest diseases to have affected the human race. Over the past few decades, the epidemiology, pathology, natural history and diagnostic methodology have been well studied. ⋯ Although it appears from this study that conservative treatment is as effective as surgical intervention for earlier and milder diseases, there are still reservations on the effect of such treatment at much longer follow-ups and for more severe diseases. Further developments in diagnosis using molecular genetic techniques, more effective antibiotics and more aggressive surgical protocols in the next millennium may help in solving the problems of late severe deformity and paraplegia in the debilitated immunocompromised patients.
