Évaluation d'un amplificateur de brillance 3D couplé à une station de navigation dans la chirurgie du bassin et du rachis‎ : étude prospective randomisée

Abstract : The objective of this prospective randomized study was the evaluation of a 3D fluoronavigation device in percutaneous and opened spine surgery, and in ilio sacral screwing. 3D fluoronavigation and conventionnal technique were compared. We have formulated 3 hypothesis : the device could increase accuracy and decrease irradiation, without statiscally increasing operative time. 150 patients have been included : 78 were operated under non navigated conventionnal surgery (37 percutaneous techniques, 35 ORIF and 6 ilio sacral screwing) and 72 were operated under 3D fluoronavigation (35 percutaneous techniques, 36 ORIF and one ilio sacral screwing). Compared to conventionnal technique, 3D fluoronavigation appeared extremely accurate in ORIF (8,7% of extra pedicular run VS 17,32%, p<0,05), without statistically increase operative time (+5,63 minutes, p=0,11), but with a greater rate of irradiation (0,47 VS 0,16mSv, p<0,05). In percutaneous surgery on the other hand, it was less accurate (13,86% of extra pedicular runs VS 11,11%, p=0,24) and slower (+10,5 minutes, p<0,05), but benefit in terms of radiation was very important (0,56 VS 1,57mSv, p<0,05). Our hypothesis are partially validated depending on type of surgeries and analysed criteria. Some factors remain limited in our study, such as few ilio sacral screwing in the navigated group, no clinical study and no inclusion of scoliotic spines, although these criteria could be analysed in other studies.
