External Fixation of Fractures
Pins inserted through the skin into bone are connected to an external frame — the preferred fixation for open fractures, polytrauma damage control, and complex periarticular injuries requiring staged management.
What is External Fixation of Fractures?
External fixation stabilises a fracture using metal pins or wires inserted percutaneously through the skin and bone on either side of the fracture, connected to a modular frame outside the body. This achieves reliable fracture stabilisation without internal implants — making it the method of choice when infection risk, soft tissue damage, or fracture complexity makes internal fixation inappropriate. External fixation includes simple uniplanar frames for straightforward shaft fractures, the Ilizarov ring fixator for complex deformity correction and bone transport, hybrid fixators for periarticular injuries, and spanning fixators across joints as part of damage-control orthopaedics in polytrauma patients.
How the Procedure Works
Pin/Wire Insertion
Schanz pins (for uniplanar frames) or tensioned fine wires (for ring fixators) are inserted through the skin and bone under fluoroscopic guidance.
Frame Assembly
Pins or wires are connected to the modular frame — uniplanar, ring, or hybrid configuration depending on the fracture and indication.
Fracture Reduction
Fine adjustments to the frame correct fracture alignment after initial application.
Wound Management
Open fracture wounds are irrigated, debrided, and managed — external fixation allows full access to the wound without obstruction.
Staged Management
The frame may be converted to internal fixation once soft tissues recover, or maintained as definitive treatment (Ilizarov for lengthening/correction).
Outcomes
Who Needs This Treatment?
- →Avoids internal implants in contaminated or open fractures — reduces infection risk
- →Rapid application in polytrauma — life-saving damage control
- →Allows full access to wound for repeated debridement and dressing
- →Adjustable after application — fine-tune alignment in the post-op period
- →Ilizarov ring fixator enables bone lengthening and deformity correction
- →Spanning fixators provide joint stability while soft tissues recover
"External fixation is a versatile, powerful tool — particularly in open fractures and complex reconstructions. The Ilizarov frame, in particular, can achieve things that no internal implant can: growing new bone, correcting deformity, and treating infected non-unions that would otherwise require amputation."
