The new Fassier-Duval Telescopic IM System (FD-rod) has the advantage of a single entry point over the traditional telescopic rods such as the Bailey-Dubow or Sheffield rods. Although encouraging early results were presented by François Fassier, there is no formal publication in the literature as yet. The first 24 consecutive cases (age 1.5-12.5 years) with a minimum of 1 year follow-up (1-2.4 years) after femoral and/or tibial FD-rods were reviewed to assess complications involving migration, non-telescoping, joint intrusion, infections and re-operation rates in patients with Osteogenesis imperfecta (OI, 15 cases), congenital tibial pseudarthrosis (CPT) in Neurofibromatosis Type1 (NF1, 2 cases), and Epidermal Naevus syndrome (1 case). In 6 cases of patients with Hypophosphataemic Rickets FD-rods were combined with an Ilizarov frame.Background
