Abstract

Fluoroscopy equipments have enabled us to perform operations that otherwise would be impossible but only at the expense of exposing the patients and theatre staff to radiation. The aim of this study was to determine the average radiation exposure to the patients in dynamic hip screw (DHS) fixation, cannulated hip screw (CHS) fixation, intra-medullary nailing (IMN) of femur and tibia operations. The records of all patients undergoing the above operations between May 2000 and August 2003 were retrospectively reviewed. A total of 670 patients were included. 389 had DHS, 85 had CHS, 125 had IMN of femur and 71 had IMN of tibia operations. The average radiation time was 0.7, 1.1, 2.5 and 2.1 min and the average radiation dose (in dose area product-DAP) was 196, 356, 548 and 125 cGy cm2 for DHS, CHS, IMN of femur and IMN of tibia, respectively. Compared to the registrars, radiation time and dose were higher with the consultants in DHS fixation (P = 0.02, 0.02). The radiation dose was higher with the senior house officers compared to the registrars in CHS fixation (P = 0.03). There were no significant differences between the consultants and the registrars in IM nailing operations. The study concludes that radiation exposure to the patients in DHS and CHS operations depends on the experience of the surgeon but not in IMN operations. The IMN of femur involved more than four times higher radiation than IMN of tibia and the CHS fixation involved double the radiation than the DHS fixation. The radiation time was poor comparative metric to estimate radiation dose.

Résumé

Les appareils de fluoroscopie nous ont permis d’exécuter des opérations qui seraient autrement impossibles, avec l’inconvénient d’exposer les patients et le personnel du bloc opératoire aux irradiations. Le but de cette étude était de déterminer l’irradiation moyenne des patients au cours d’ostéosynthèses par vis dynamique du fémur proximal (DHS), vis cannulée du fémur proximal (CHS), enclouage centromédullaire (ECM) du tibia et du fémur. Les dossiers de tous les patients ayant subit les susdites opérations entre mai 2000 et août 2003 ont été rétrospectivement passés en revue. Un total de 670 patients a été inclus. 389 avait eu une DHS, 85 une CHS, 125 un ECM de fémur et 71 un ECM du tibia. La durée moyenne d’irradiation était de 0.7, 1.1, 2.5 et 2.1 minutes et la dose moyenne de radiations était de 196, 356, 548 et 125 cGy cm2 respectivement pour les DHS, CHS, ECM de fémur et ECM de tibia. Comparé aux chefs de clinique, le temps d’irradiation et la dose étaient plus importants avec les chirurgiens confirmés dans l’ostéosynthèse par DHS (p = 0.02, 0.02). La dose de radiations était plus importante avec les internes qu’avec les chefs de clinique dans le vissage par CHS (p = 0.03). Il n’y avait aucune différence significative entre les chirurgiens confirmés et les chefs de clinique dans l’ECM. L’étude conclut que l’irradiation des patients dans les DHS et les CHS dépend de l’expérience du chirurgien, mais pas dans les ECM. L’ ECM du fémur a provoqué une irradiation plus de quatre fois plus importante que celle de l’ECM du tibia et le vissage par CHS provoque une irradiation deux fois plus importante que celle du vissage par DHS. La durée d’irradiation était un moyen peu efficace pour évaluer la dose d’irradiation.
