Complex Trauma Limb Salvage & Reconstruction
Circular External Fixator for Trauma & Reconstruction
OVERVIEW
Circular external fixators are orthopaedic implants that use rings, wires, and pins to stabilize the bone after surgery. Unlike plates or nails that are covered by skin or muscle, circular fixators are situated on the outside of one’s limb.
THE SIGNIFICANCE OF CIRCULAR FIXATORS IN COMPLEX TRAUMA AND LIMB RECONSTRUCTION
Circular external fixators are an excellent tool in the management of complex trauma and limb reconstruction challenges. Many limb reconstruction centres around the world use circular fixators for their versatility in managing complex orthopaedic pathologies.
WHAT ARE THE BENEFITS OF CIRCULAR EXTERNAL FIXATORS?
- It’s less invasive compared to other surgeries like plate or nail fixation.
- It has a low risk of infection
- It is highly versatile and can perform many functions simultaneously
- It is adjustable after surgery
- Immediate full weight-bearing after surgery
