We report the management of two children and 1 1 adults with paraplegia secondary to vertebral hydatidosis. Destruction of pedicles, posterior vertebral elements and discs as well as the vertebral bodies was common and all six patients with thoracic disease had involvement of adjacent ribs. The 13 patients had a total of 42 major surgical procedures; two patients died from postoperative complications and four from complications of the disease and paraplegia. All eight patients initially freated by laminectomy or anterior decompression alone relapsed within two years and seven required further surgery. Circumferential decompression and grafting gave the best results, six of nine patients being in remission an average of three years and six months later. The prognosis for such patients is poor; remission is the aim, rather than cure. Anthelminthic drugs may improve the prognosis, but radical surgery is likely to remain the keystone of treatment in the foreseeable future. The incidence of human infestation with Echinococcus granulosus is increasing, and the parasite is appearing in areas of the world previously free of it (Williams, Lopez, Adaros and Trejos 1971 ; Matossian, Rickard and Smyth 1977). We report the treatment and results of 13 patients with paraplegia due to vertebral hydatidosis.

La luxation de la tête radiale dans le cadre de la maladie exostosante constitue une complication de déséquilibre de croissance des deux os de l'avant bras secondaire à une exostose distale de l'ulna. Le traitement est difficile et controversé par les auteurs. Nous présentons une technique originale pour le traitement de cette entité. Après la correction de l'index radio-cubital inférieur par un allongement progressif de l'ulna, une fixation radio-cubitale inférieure par les fiches distales de l'Orthofix® et un deuxième allongement de l'ulna permet l'abaissement de la tête radiale et sa réduction. La réduction progressive par allongement de l'ulna par la méthode de callotasis constitue une technique séduisante et réalise l'inverse du ce qui passé lors de ralentissement de croissance de l'ulna sous l'effet de l'exostose ulnaire.
