Comparative Study Clinical Trial
Treatment of idiopathic scoliosis with side-shift therapy: an initial comparison with a brace treatment historical cohort.
A group of 44 patients with idiopathic scoliosis (mean age 13.6 years) with an initial Cobb angle between 20 degrees and 32 degrees received side-shift therapy (mean treatment duration 2.2 years). A group of 120 brace patients (mean age 13.6 years) with an initial Cobb angle in the same range (mean brace treatment 3.0 years) was the historical reference group. ⋯ The difference in the mean progression of the Cobb angle for the respective groups is small (for efficiency: 3 degrees vs -2 degrees, for efficacy: 2 degrees vs -1 degrees ). Side-shift therapy appears to be a promising additional treatment for idiopathic scoliosis in adolescents with an initial Cobb angle between 20 degrees and 32 degrees.

Clinical Trial
Lumbar spine stability can be augmented with an abdominal belt and/or increased intra-abdominal pressure.
The increased intra-abdominal pressure (IAP) commonly observed when the spine is loaded during physical activities is hypothesized to increase lumbar spine stability. The mechanical stability of the lumbar spine is an important consideration in low back injury prevention and rehabilitation strategies. This study examined the effects of raised IAP and an abdominal belt on lumbar spine stability. ⋯ The belt had no effect on the activity of any of the muscles with the exception of the thoracic erector spinae in extension and the lumbar erector spinae in flexion, whose activities decreased. The results indicate that both wearing an abdominal belt and raised IAP can each independently, or in combination, increase lumbar spine stability. However, the benefits of the belt must be interpreted with caution in the context of the decreased activation of a few trunk extensor muscles.

The Modular Type SB Charite disc prosthesis has been developed as a device for artificial disc replacement (ADR) in patients with symptomatic discopathies. Here, we report on our first series of 50 (out of 350) patients, who had a satisfactory clinical result in 70% of cases (2 years' follow-up). Subgroup analysis revealed that patients with an isolated discopathy without previous spinal operations or other pathology at the same or other spinal level benefitted more from the surgery. ⋯ We conclude that in patients with severe isolated symptomatic discopathies that are resistant to conservative treatment, a mobile disc prosthesis is worth considering as a real alternative to a spondylodesis. However, accurate patient selection is imperative. With these criteria we were encouraged by our results to continue the implantation of this artificial disc.

An unusual case of vertical atlantoaxial dislocation without medulla oblongata or spinal cord injury is reported. The pathogenic process suggested occipito-axial dislocation. The case was treated surgically with excellent results on mobility and pain.

Case Reports
Acute spinal cord compression due to intraspinal bleeding from a vertebral hemangioma: two case-reports.
Vertebral hemangiomas can cause acute spinal cord compression either after a minor trauma or during the last 3 months of pregnancy. Failure to recognize the lesion can lead to potentially serious treatment delays. An emergency MRI scan usually establishes the diagnosis of vertebral hemangioma responsible for spinal cord compression requiring laminectomy. We report two cases showing that posterior fixation should be considered: in our experience it prevents vertebral collapse during the interval preceding secondary vertebroplasty, which, if performed, provides highly significant pain relief.
