A telescopic, self-extending intramedullary nail that lengthens as the bone grows — a reference solution for osteogenesis imperfecta and other skeletal dysplasias.
Fassier-Duval is a telescopic intramedullary nailing system developed by Pega Medical (an OrthoPediatrics group company), designed for patients with osteogenesis imperfecta (OI), skeletal dysplasias, and other bone deformities. The nail lengthens (“telescopes”) as the bone grows, preventing or stabilizing fractures and correcting long-bone deformities during growth.
The system consists of a female component, anchored in the proximal cortex, and a male component, anchored at the distal epiphysis, with threaded fixation. Unlike conventional telescopic nails (Bailey-Dubow, Sheffield), Fassier-Duval uses a single entry point, reducing invasiveness.
It is used as a temporary implant for the healing of diaphyseal fractures, osteotomies, nonunions, and malunions, and for the prevention of fractures of the femur, tibia, and humerus in pediatric patients. It can also be used in bone lengthening/shortening, together with external fixators, in pediatric or small-stature patients with limb-length discrepancy.

A study that evaluated the risk of migration of Fassier-Duval rods in patients with osteogenesis imperfecta undergoing spinal MRI (1.5 T magnet), as well as heating effects and artifacts. Conclusion: FD rods are safe at 1.5 T MRI, with no significant migration, heating, or artifacts.

A description of a retrograde humeral rodding technique with Fassier-Duval in children with OI, for fractures/bowing of the distal half of the bone. In the 6 patients included, all fractures/osteotomies healed with functional alignment, with no intraoperative surgical complications.
