osteobridge-ikaKnee Arthrodesis Rod Fixation System

Merete Medical has received the FDA clearance to market its Merete OsteoBridge IKA Intramedullary Knee Arthrodesis Rod Fixation System for fusion of the knee joint. Indications include:

 

 

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

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.
