Cross-sectional, population-based survey. ⋯ Young people are more likely to suffer from asthma and headache, but not from atopic dermatitis/hay fever, if they have low back pain. All of the investigated disorders cluster in some individuals. A model of common origin for these seemingly independent disorders should be considered.

A 3-year prospective, cohort study. ⋯ Dysphagia is a common occurrence after AC procedures but was also found after PC procedures. Intubation alone was not a risk factor for postoperative dysphagia in this cohort.

The effects of bone cement placement, volume, and bone density on the degree of biomechanical reinforcement on cadaveric vertebral bodies were studied using experimentally calibrated detailed finite element models. ⋯ Prophylactic vertebroplasty can be effective in reducing fracture risk. However, for the polymethyl methacrylate volume (20%) required for the successful reinforcement of high-risk vertebral bodies, the risk of complications will be as high as that for current vertebroplasty procedure for fracture repair. Therefore, alternative materials have to be investigated for prophylactic vertebroplasty. Furthermore, bipedicular vertebroplasty is the recommended approach due to its higher strengthening effect and easier surgical access than the posterolateral case.

A retrospective review with clinical and radiologic assessment was conducted. ⋯ Twenty-three patients with tuberculosis of the lower lumbar spine underwent posterior instrumentation with laminar hooks and anterior interbody arthrodesis by a single surgeon. The clinical outcomes were evaluated with preoperative and postoperative questionnaires, and the radiographs were independently analyzed with respect to fusion status and sagittal angle. RESULTS.: The mean follow-up period was 28.7 months (range, 24-39 months). The average preoperative, immediate postoperative, and final follow-up sagittal angles were 2.7 degrees, -14.1 degrees, and -11.5 degrees, respectively. There was a mean reduction of 16.7 degrees (range, 9 degrees-23 degrees) after surgery. Two patients had a correction loss more than 5 degrees during the follow-up period. Bony fusion was obtained in all patients. There was no recurrence of the disease. CONCLUSION.: This technique appears to be effective in stabilizing the vertebrae, restoring lordosis, achieving a solid fusion, and improving clinical outcome without sacrificing additional motion segments.
