Universal Fracture Healing Accelerator for External Fixators

HKU
Overview

A novel accelerator that speeds up fracture healing by 20% by creating weight-bearing like micromotion at the fracture site

  • Universal Fracture Healing Accelerator for External Fixators
Problem addressed

• Delayed union or non-union are common in fracture healing • 5-10% of fractures resulted in non-union. • Clinically, a new way to accelerate fracture healing and to reduce non-union rate is needed

Innovation
  • Creating weight-bearing like micromotion at the fracture site
  • This NEW ACCELERATOR can be adapted to different external fixators
Key impact
  • The new accelerator (MMU) speeds up fracture healing by 20%.
  • In rodent model, clear bone formation at week 6 after operation was observed with MMU applied to external fixator
  • The new accelerator can provide adjustable uniform strain at the fracture site during treatment with a feedback correction mechanism.
