title: The Lyon brace.
abstract: The Lyon Brace or adjustable multi-shells brace has been used for more than 60 years. Three types of braces have been developed: Lyon thoracic brace, Lyon thoraco lumbar brace and Lyon lumbar brace. Considering the conservative orthopaedic treatment of scoliosis we outline the results of this orthosis. The management of the Lyon Brace includes: (i) The use of one or two reductive plastered brace which enable a flow of the concavity ligaments; (ii) a moulding either hand-oriented or electronic after the resection of the plastered brace; (iii) a blueprint adapted to Lenke's classification; and (iv) a specific physiotherapy. The protocol of the wearing of the orthosis depends on the initial angulation of the scoliosis. The effectivity index of 1338 scoliosis checked at least two years after the weaning of the brace, is 0.95. The effectivity index is 0.80 when the Lyon brace is put in place at Risser 0. If the angulation is globally stabilized, the rib hump is, on average, half reduced. We get the best results for lumbar scoliosis and double major. The technological progresses allow a precise use. The adjustment becomes easy during puberty growth.
