  1. A statistic approach to electronic moulding versus traditional plaster moulding Jean Claude de Mauroy, FrédéricBarral, Cyril Lecante

  2. 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?

  3. Adjusting position

  4. Comparing virtual vertebral reconstruction and real X ray

  5. Full 3D Electronic Moulding

  6. automatic modification of the shape

  7. 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).

  8. Lumbar brace Plaster cast Init

  9. 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.

  10. Anatomo-radiological classification

  11. In Brace angular reducibility 73 % 69 % 54 %

  12. Comparative results

  13. Electronic versus Plaster Moulding But nonsignificant 5.44° 4.75° 3.89° 3.63° 3.02° 2.14°

  14. 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.
