✦ Synopsis

Internal fixation with a Herbert screw was used to treat 70 ununited fractures of the carpal scaphoid. Bone grafts were utilised in all cases of nonunion ( 56) and in 10 out of 14 with delayed union. The results were assessed at a mean time of 13 months. Definite radiographic union was achieved in 90% of patients after a mean period of postoperative immobilisation of 5.4 weeks. Although the rate of union was basically the same as in Russe's series, the final functional results were better than those obtained by using his technique. The use of an image intensifier is essential to avoid technical problems.

R+sum+. Nous avons traitb 70 pseudarthroses du scaphoide carpien par ostbosynthOse au moyen de vis de Herbert. L'bvaluation des rdsultats a btb faite avec un recul moyen de 13 mois. Une fusion osseuse certaine a btb obtenue dans 90% des cas aprOs une immobilisation post-opkratoire de 5.4 semaines en moyenne. Bien que le taux de consolidation soit le mOme que dans les sbries opbrbes selon la technique de Matti-Russe, le rbsultat fonctionnel final est meilleur. L'utilisation d'un amplificateur de brillance est essentielle, permettant de pallier les pro-blOmes techniques per-opbratoires.
