A new RSC brace design to treat single long thoracic scoliosis. Comparison of the in-brace correction in two groups treated with the new and the classical models
The purpose of this study was to compare two different scoliosis brace designs in the treatment of a particular curve pattern.
Background
The Chêneau brace is considered one of the standards in the treatment of juvenile and adolescent idiopathic scoliosis. The RSC brace, a Chêneau derivate, uses a specific clinical and radiological classification in order to define the most effective principles of correction. (Figure 1)

Methods
In this case control study, 11 patients with long thoracic curves (imbalanced three-curve pattern or A1 from the Rigo classification) were treated with a specifically designed RSC brace called "three curves brace with open pelvis." These 11 patients were compared to a control group of 10 patients with the same age and curve magnitude, treated with a classical RSC brace for a three-curve scoliosis pattern. Patients with a combined upper thoracic structural curve were not included in any of the groups. The mean age was 10.5 years, mean Cobb angle was 29.5°, and mean axial rotation was 15°. The compared values were the in-brace correction of the Cobb angle and the axial rotation.
Results
The in-brace correction of the Cobb angle was 76.7% in the study group compared to 43.3% in the control group (p < .005). The in-brace correction of the axial rotation was 55.9% in the study group compared to 29.9% in the control group.
Conclusion
In-brace correction of the Cobb angle and axial rotation can be improved in patients with long thoracic curves treated with a recently described brace design ("three curves brace with open pelvis") in comparison with the classic RSC model for this curve pattern.

Bewegungs-, Dehnungs- und Entspannungsübungen im Wasser lindern die Beschwerden von Patientinnen mit Fibromyalgie besser als das Üben auf trockenem Land. Das geht aus einer spanisch-brasilianischen Vergleichsstudie hervor.
Darauf haben viele Praxen gewartet: Das Zi hat eine Liste von Praxisverwaltungssystemen veröffentlicht, die von Nutzern positiv bewertet werden. Eine gute Grundlage für wechselwillige Ärzte und Psychotherapeuten.
Mit dem demographischen Wandel versorgt auch die Chirurgie immer mehr betagte Menschen. Von Entwicklungen wie Fast-Track können auch ältere Menschen profitieren und bei proximaler Humerusfraktur können selbst manche 100-Jährige noch sicher operiert werden.
Patienten, die von Ärztinnen behandelt werden, dürfen offenbar auf bessere Therapieergebnisse hoffen als Patienten von Ärzten. Besonders scheint das auf weibliche Kranke zuzutreffen, wie eine Studie zeigt.
