Comparative Study[Validation of the North American Spine Society Instrument for assessment of health status in patients with chronic backache].
Pain and functional limitations are the chief symptoms in patients with back pain. However, standardized assessment of these domains are still not commonplace in clinical practice. The objective of this study was the cultural adaptation and validation of the North American Spine Society (NASS) Lumbar Spine Outcome Assessment Instrument for German speaking patients with back pain. ⋯ The German version of the NASS Cervical and Lumbar Spine Outcome Assessment Instrument allows the standardized assessment of pain, functional limitations and neurogenic symptoms in patients with back pain and the international comparison of health states and therapeutic outcomes.

[Effect of Harrington instrumentation spondylodesis on scoliotic thoracic deformity. A retrospective 5-year analysis].
Harrington-Instrumentation (HI) was the golden standard of scoliosis surgery for more than two decades and is still frequently used. The effects of instrumentation on rib hump reduction in long term follow-up is not well documented. 104 patients with idiopathic thoracic scoliosis were studied with a minimum follow-up of five years (min. 5 y., max. 8 years). ⋯ HI leads to a permanent and stable improvement of the frontal plane including apical vertebral translation. HI does not have derotational capabilities. The effect of the rib-cage deformity was less impressive with loss of correction at follow up.
