Biphasic Plate Distal Femur

Ladina Hofmann-Fliri, Devakar Epari, Markus Windolf, Christoph Sommer

Severe trauma to the extremities is a leading cause of disability during the wage-earning period. The socioeconomic burden of fracture is substantial. Loss of working capacity can account up to 50% of the total costs of the fracture [1]. Optimal outcomes require not only solid bone union but also early and complete recovery of limb function. The current generation of fracture fixation plates focuses on minimizing the impact of surgery and preserving the biological healing potential. However, their design poorly controls a second critical component—the mechanical environment of the fracture. Furthermore, these plates are prone to failure which limits function and delays return to work.

The Biphasic Plate (Fig 1) is designed to provide suitable flexibility for healing and increased implant strength to support early full weight bearing.
