Biomechanical action of a corrective brace on thoracic idiopathic scoliosis: Cheneau 2000 orthosis.

Purpose: To provide a detailed description of the mechanisms responsible for the corrective effect of the rigid brace Cheneau 2000.

Methods: Morphology of thoracic scoliosis is presented, including surface trunk asymmetries and radiological deformation. Biomechanical rules, applied to achieve curve correction in the three planes, are the subject of a comprehensive review.

Passive and active mechanisms of correction of thoracic idiopathic scoliosis with a rigid brace.

Contemporary bracing developed numerous novel technical solutions to most of main aspects of the correction of structural progressive idiopathic scoliosis. This paper presents a short review on principal biomechanical rules for the three dimensional scoliosis correction. Apart from the tissue transfer, which is a known passive mechanism of rigid bracing, the other passive mechanisms are described, containing the "cherry stone" distraction effect, the thoracic derotation and the bending.

[Sports injuries in children. Epidemiologic study].

Among 49 000 cases of infantile emergencies which were received in the BUCI (Bloc d'urgence chirurgical infantile: surgical infantile emergency unit), 5 546 were sport traumas. At an early age, they were caused by outdoor plays; during adolescence, the main cases were caused by team sports. Males are predominant.
