Introducing the F-REX Screw

Designed for patients with osteoporotic bone and complex fractures, the F-REX Screw is an expandable lag screw that is used for peritrochanteric femoral nailing. The expansion is designed to increase fixation strength to minimise screw migration and fracture displacement to avoid anatomical misalignment and reduce the risk of screw cut-out into the hip joint or non-union. The F-REX Screw is designed to be easy to use and remove with less than 1 minute increase in surgery time compared to a standard nailing system.

The F-REX Screw can be reliably removed, as demonstrated in a large animal study

  • Bilateral implantation in femoral condyle of 5 sheep (n=10) with 4 months in vivo.
  • No viable bone ingrowth into mechanism.
  • All samples successfully retracted and removed with no complications.
  • Average retraction torque 0.3Nm (0.1-0.5 Nm).
