A statistic approach to electronic moulding versus traditional plaster moulding Jean Claude de Mauroy, Frédéric Barral, Cyril Lecante
Background Electronic moulding tends to gradually replace the plaster moulding. Is it as effective? There is no study on the results obtained by this process for the scoliosis. In the department of orthopaedic medicine of the Clinique du Parc - Lyon, the electronic moulding replaced the traditional plastered moulding in May, 2008. Are the radiological angular corrections better in brace?
Methodology The angular correction of 166 plaster moulding scoliosis was compared with the correction of 117 electronic moulding scoliosis (random). Both mouldings were made by the same physician. The electronic moulding has been produced using the full 3D system ORTEN. The curves have been grouped into thoracic (n=127), thoracolumbar(n=65) and lumbar(n=206).
Results The average initial angle is: 28,19 (+-9,21) for thoracic, 28,11 (+-9,34) for thoraco-lumbar and 25,86 (+-7,04) for lumbar curves. The angular reducibility is 54 % in braces for the thoracic curvatures, 69 % for the thoraco- lumbar curvatures and of 73 % for the lumbar curvatures, which corresponds to the usual results of the Lyon management.

Conclusion Such results are in favour of the electronic moulding which remains however delicate and require: a precise position of the patient during the surface topography and well trained orthotic technicians.
