The purpose of this study was to determine prognostic criteria for return to work 9-12 years after standard nucleotomy for herniated nucleus pulposus confirmed by CT. From 1985 until 1988, 182 patients (102 male, 80 female, mean age 45 years) with a single-level herniated nucleus pulposus were operated on for the first time. In summer 1997, an average of 10.2 years after the operation, 101 of 182 patients (55.5%) returned a standardised questionnaire. ⋯ Group II contained 57 patients, of whom 18 worked only part of the time, 9 had changed to a lighter full-time job, 23 had taken early retirement, and 7 were receiving a pension. Patients in group I were significantly younger (38 vs. 51 years), had a smaller proportion of patients with more than 20% overweight (27% vs. 44%), had a smaller proportion of severe, grade 0 and 1, motor dysfunction (0% vs. 16.3%), had been operated sooner (within 3 days: 52.3% vs. 19.3%), had undergone fewer re-operations for recurrence of the herniation (4.5% vs. 21.1%), and had worked less frequently in physically demanding jobs (6.7% vs. 22.8%). We concluded that when there is a relative indication for herniated nucleus pulposus surgery, it should be limited to patients aged below 40 years, with slight motor dysfunction, who work in physically undemanding jobs, so as to make a satisfactory long-term result more likely.

One of the most common complications of lumbar spine surgery is peridural fibrosis, a fibroblastic invasion of the nerve roots and the peridural sac exposed at operation. Peridural fibrosis may produce symptoms similar to those the patient experienced preoperatively and, if another spinal operation is necessary, may increase the risk of injury at reexposure. In a controlled study in dogs, we assessed the use of expanded polytetrafluoroethylene (ePTFE) as a barrier to postoperative invasion of fibrous tissue into the laminectomy defect. ⋯ No foreign-body reactions to the membrane or membrane-related infections occurred. We conclude that the ePTFE spinal membrane, when properly implanted, is an effective barrier to postsurgical fibrous invasion of the vertebral canal. Clinical studies of use of this material in spinal surgery are warranted.

Somatic and mental symptoms in 22 patients (16 women and 6 men) 22-73 months after a whiplash injury are described. The results of the present study are compared with the corresponding results of a previous study on the same patients. According to the Quebec Classification System, the whiplash injuries of 15 patients were classified as grade 2 and those of 7 patients as grade 3. ⋯ The Mood Adjective Check List was used as a measure of mental well-being. During the 2 years that had passed since the previous study, the patients had improved regarding pain intensity, pain tolerance level and mental well-being. The results show that patients with prolonged disability after a whiplash injury can improve even after a long time.

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.
