Abstract

We reviewed 36 consecutive patients, 24 males and 12 females, presenting to our institution, a tertiary referral spinal trauma centre, over a 6-year period. The mean age was 46 (range18–82 years) years. We assessed: (a) the mechanism of injury, (b) the mode of treatment, (c) the radiographic classification using the Levine and Edwards system and (d) functional outcome using the cervical spine outcomes questionnaire (CSOQ) by BenDebba. The commonest mechanism of injury was road traffic accidents. There were 14 Type-I, 11 Type-II and 1 Type-IIA fractures. Twenty-seven patients were treated with halo-vest immobilisation and nine were immobilised in a Minerva jacket. All fractures demonstrated radiographic union at a mean of 12 (range 10–16) weeks. There were no neurological complications. Upon review, all patients, whether Type-I or Type-II demonstrated low CSOQ scores approaching their pre-morbid status. However, Type-II fractures scored higher in three functional outcome categories when compared to Type-I fractures.

Résumé

Nous avons revu 36 patients, 24 hommes et 12 femmes, pris en charge dans notre institution sur une période de 6 ans. L’âge moyen était de 46 ans (18–22). Nous avons étudié le type de mécanisme, le traitement utilisé, le type radiologique de lésion selon la classification de Levine et Edwards, le résultat fonctionnel sur la base du score fonctionnel pour le rachis cervical. Les accidents de la circulation étaient la cause du traumatisme la plus fréquente. Il y avait 14 types 1, 11 types 2 et 1 type 2A. 27 patients ont été traités par halo plâtre et 9 par minerve plâtrée. Toutes les fractures ont consolidé avec un délai moyen de 12 semaines (10–16). Il n’y a pas eu de complications neurologiques. A la révision tous les patients présentant une lésion de type 1 ou de type 2 avaient un score fonctionnel du rachis cervical bas, voisin de leur état prétraumatique. Cependant les types 2 obtenaient un score supérieur dans 3 catégories fonctionnelles.
