The Fassier-Duval Telescopic IM SystemTM

The nail that grows with your patient!

The Fassier-Duval Telescopic Intramedullary System is a self extending rod designed for patients suffering from Osteogenesis Imperfecta (OI), skeletal dysplasia and other bone deformities. Created to prevent or stabilize fractures, or correct deformity of long bones whilst growth occurs.

The design of the rod includes a female component (which is attached to the proximal epiphysis) and a male component (which is attached at the distal epiphysis). It is available in five diameters: 3.2, 4.0, 4.8, 5.6 and 6.4 mm, up to 420 mm in length.


The gold standard in treatment of:

  • osteogenesis imperfecta
  • Congenital tibial pseudoarthrosis
  • Skeletal dysplasias

This implant is indicated as a temporary implant to aid in the healing of long diaphysis fractures, osteotomies, malunions and nonunions and to prevent further fractures in the femur, tibia and humerus of pediatric patients. It can also be used in procedures such as bone lengthening/shortening concomitantly with external fixators in pediatric or small stature patients with limb length discrepancy.

  • Advanced screw fixation design
  • Novel surgical approach: Insertion prevents violation of the articular joint
  • Minimally invasive
  • Allows patient growth while stabilizing fractures
