Treatment of Osteogenesis Imperfecta Using the Fassier-Duval Telescopic Rod

Abstract

Objectives: This study aimed to assess the treatment of patients with Osteogenesis Imperfecta (OI) operated on with a telescopic Fassier-Duval (FD) rod in a querterenario hospital from 2010 to 2020. Methods: We analyzed indication for surgical treatment, causes of reoperation, complications and the effectiveness of telescoping rod. Results: The results were compared with the literature and with the same parameters from a previous study which a different telescopic rod developed by the same authors. This was a retrospective study based on the analysis of digital and radiographic clinical records. Fifteen patients with 21 FD rods were evaluated, most were used on the femur (18 rods or 85.7%), eight patients were female (53.3%), with a mean age of 10.47 (3.92 to 16.44) years, most of whom had type III Sillence (46.7%), with a mean follow-up of 5.22 (1.43 to 7.02) years. Seven rods (33.3%) had complications. The main indication was for fracture (57.1%). Regarding the ability to telescope, we observed that 15 rods (71.4%) followed the child's growth. Conclusion: We had good results using FD rods, similar to the data found in the literature and the data obtained with our rod. Level of Evidence III,Retrospective comparative study .
