The effect of a device for transverse traction on vertebral rotation in surgery for scoliosis as studied by X-ray stereophotogrammetry

  • 44 Accesses

Summary

The effect of a device for transverse traction (DTT) on vertebral rotation in surgery for scoliosis has been analysed with an X ray stereophoto-grammetric method in 17 patients. Six of them underwent conventional Harrington rod instrumentation and eleven patients received additional treatment with the DTT. The DTT exerted a positive effect on vertical rotation at the apex, and derotation average 10° as compared with 5° in the group in whom the device was not used.

Résumé

L'effet d'un système de traction transversale (STT) sur la rotation vertébrale dans la chirurgie de la scoliose a été étudié chez 27 malades grâce à une méthode radiologique de stéréophotogrammétrie. Six d'entre eux furent instrumentés de façon conventionnelle par tiges de Harrington et onze bénéficièrent d'un traitement complémentaire par le STT. Celui-ci exerça un effet positif sur la rotation verticale au sommet de la courbure et la dérotation atteignit 10° en moyenne, contre 5° dans le groupe dans lequel ce système n'avait pas été utilisé.
