Sheffield Ring Fixator

The Sheffield™ Ring Fixation System has been designed to achieve rapid assembly and high stability both in trauma and reconstruction.

Physician Benefits

  • Lightweight, radiolucent carbon fiber construction
  • Central slots allow multiple levels of wire fixation at higher tension
  • Circumferential grooves allow versatile wire placement
  • Two-thirds and one-third rings which may be joined as a full ring set to protect soft tissue, or allow wire placement at a wider angle
  • High strength construction with reinforced anterior section to support wire tension​


Acute Trauma

  • Tibial articular fractures: plateau and pilon
  • Tibial articular fractures with diaphyseal extension
  • High energy diaphyseal fractures of the tibia
  • Femoral fractures, particularly distal
  • Humeral fractures
  • Fractures in osteoporotic bone
  • Complex joint injuries where soft tissue or bony injury is such that fixation should be taken across the knee or ankle joint​

Limb Reconstruction

  • Correction of post-traumatic, acquired and congenital deformities: simple, juxta-articular, oblique plane, multiplanar. The Sheffield Ring Fixator is usually used in the lower limb for tibial and foot deformities, but is also useful for femoral and knee deformities. It may also be used in the upper limb, particularly the humerus
  • Arthrodesis: knee, ankle and subtalar joints
  • Limb Lengthening: monofocal and bifocal
  • Nonunion and bone loss:
    • Monofocal – compression, neutralization, distraction
    • Bifocal – bone transport, acute shortening, combined multifocal
  • Joint contracture in adults and children: knee, ankle and foot
  • ​Articulated distraction: ankle, foot and knee​


  • Patients with mental or physiological conditions who are unwilling or incapable of following postoperative care instructions
  • Patients with severe osteoporosis, patients who are HIV positive and patients with severe, poorly controlled diabetes mellitus
  • Patients with foreign body sensitivity. Where material sensitivity is suspected, tests should be made prior to implant insertion
