The modular system for the fixation of the knee joint


The Concept:

In contrast to one-piece intramedullary nails, the modular design allows for insertion through a single incision at the knee, with retrograde insertion into the femur and antegrade insertion into tibia. This can be advantageous for an obese patient, in whom the approach to the piriformis fossa is difficult. At the same time the system accommodates dissimilar diameters of the femoral and tibial intramedullary canals, thus achieving a better press fit and stabilization of Femur and Tibia.

Also, unlike the situation with a standard intramedullary nail, the physiological genu valgum of the extremity can be maintained. In contrast to a one-piece intramedullary nail, the modular system with its two components fixed with a stable coupler, allows the accommodation of the nail to the contour of the femoral shaft, thus reducing the risk of fracture during insertion.

Surgical Case Studies:

Pre- and postoperative:




  • Failed total knee arthroplasty
  • Limb salvage
  • Oncology surgery
  • Any other condition where there is a little soft tissue or bony tissue available for support and arthrodesis is the treatment of choice



  • The custom modularity of the system enables intraoperative adaption to the bone defect by using varibale nail diameters and lenghts
  • Primary stability is achieved by press-fit
  • Secondary stability is achieved with biological integration of the stems into the bone structure (osseointegration) stimulated by a brushed titanium surface
  • Distal interlocking screws provide rotational stability
  • By rotating the angled spacer, the surgeon may adjust both the extension/flexion and valgus/varus positioning of the joint
  • Hollow spacer shells can be used as a carrier of antibiotics as well as bone graft
  • Trial nails and a trial spacer for an intraoperative selection of implant components
  • Cementless and cemented implantation possible



  • All components are made of Ti6Al4V
