Fixateur d’anneau Sheffield

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

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
