Overview

External Fixation is a critical orthopedic trauma technique that uses pins or wires inserted into bone above and below a fracture site, connected to an external metal frame for stabilization. This approach is particularly valuable for managing open fractures (Gustilo classification Type I, II, and III), polytrauma cases, severe soft tissue injuries, and fractures complicated by infection or vascular damage. At Arthroscenter, Dr. Gurudeo Kumar brings extensive expertise in damage control orthopaedics and complex trauma management, essential in Bihar's context where road traffic accidents and agricultural injuries frequently result in severe open fractures. Our facility is equipped to handle all classifications of open fractures, from simple wounds to extensive soft tissue damage requiring staged reconstruction. We utilize both temporary external fixation for acute stabilization and definitive fixation including advanced Ilizarov techniques for bone transport and limb lengthening. The external fixator serves multiple purposes: immediate fracture stabilization in polytrauma patients, soft tissue management in contaminated wounds, length maintenance in severe comminuted fractures, gradual correction of deformities, and bone regeneration through distraction osteogenesis. Treatment may involve temporary external fixation followed by conversion to internal fixation once soft tissues heal, or definitive external fixation maintained until complete bone union. Our multidisciplinary approach includes coordination with plastic surgery for soft tissue coverage, vascular surgery for limb-threatening injuries, and intensive physiotherapy to maintain joint motion during the extended treatment period typical of severe open fractures.

Procedure Details

Duration

1.5-3 hours depending on fracture complexity, soft tissue injury severity, and whether temporary or definitive fixation is planned. Polytrauma damage control external fixation may be completed in 30-45 minutes.

Anesthesia

General anesthesia for polytrauma and complex cases; regional anesthesia (spinal/epidural) for isolated lower extremity fractures; occasionally local anesthesia with sedation for simple frame applications in hemodynamically unstable patients.

Preparation for Surgery

Patient evaluation includes classification of open fracture severity (Gustilo-Anderson), assessment of neurovascular status, tetanus prophylaxis, broad-spectrum antibiotics, and urgent debridement of contaminated wounds. Radiographs in multiple planes guide fixator planning. In polytrauma, external fixation is performed as part of damage control resuscitation after life-threatening injuries are stabilized.

Surgical Steps

Emergency wound debridement: Thorough irrigation with copious normal saline (6-9 liters), removal of contaminated and devitalized tissue, foreign material extraction, and wound classification. Multiple staged debridements may be required for Gustilo Type III injuries.

Fracture reduction: Alignment of bone fragments using manual traction or temporary clamps under fluoroscopic guidance to restore length, rotation, and angulation. In severe comminution, anatomic reduction may not be possible initially.

Pin insertion sites: Strategic placement of Schanz pins or smooth wires in safe corridors avoiding neurovascular structures, typically 2-3 pins above and below the fracture site in solid bone. Pre-drilling prevents thermal necrosis and reduces infection risk.

Pin fixation to bone: Bicortical purchase of pins through both near and far cortices for maximum stability, using low-speed drilling with copious irrigation to prevent heat generation. Pin angle and spread optimized for frame rigidity.

External frame assembly: Connection of pins to carbon fiber or stainless steel rods using clamps, creating a stable construct. Frame may be unilateral, bilateral, circular (Ilizarov), or hybrid depending on fracture pattern and soft tissue condition.

Stability verification: Fluoroscopic confirmation of fracture reduction in multiple planes, assessment of frame rigidity, and adjustments as needed. For temporary fixation in polytrauma, rapid application prioritized over perfect reduction.

Soft tissue management: Leave contaminated wounds open for delayed primary closure or coverage with skin grafting/flap procedures once infection is controlled. Vacuum-assisted closure devices may be used for wound management.

Pin site care and dressing: Sterile dressings applied to pin entry points, patient and family education on daily pin care protocol to prevent pin tract infections, which occur in 10-30% of cases.

Recovery Timeline

What to expect during your recovery journey

Week 1-2

Initial Stabilization & Wound Management

Daily pin site care with antiseptic solution, serial wound debridements if needed, IV antibiotics for open fracture, pain management, and early joint mobilization above and below the frame to prevent stiffness. Monitor for compartment syndrome and vascular compromise.

Week 3-6

Soft Tissue Healing & Frame Adjustment

Progressive weight-bearing as tolerated (typically partial weight-bearing 10-20kg), wound closure or coverage procedures, transition to oral antibiotics, pin site surveillance for infection (erythema, drainage, loosening), and frame adjustments to maintain reduction as swelling subsides.

Week 6-12

Bone Healing Monitoring

Regular X-rays every 2-3 weeks to assess callus formation, increased weight-bearing (50-75% body weight) with walker or crutches, continued pin care, physical therapy for joint range of motion, and decision-making regarding conversion to internal fixation versus continued external fixation based on soft tissue and bone healing.

Month 3-6

Advanced Healing or Definitive Fixation

For temporary external fixation: conversion to internal fixation (plate/intramedullary nail) once soft tissues healed. For definitive external fixation: progressive increase to full weight-bearing, dynamization of frame (removing select connecting rods to allow controlled motion and stimulate healing), radiographic confirmation of bridging callus in 3 cortices.

Month 6-12

Frame Removal or Ilizarov Treatment Completion

External fixator removal once clinical (no pain/motion at fracture site) and radiographic union achieved, typically 3-6 months for tibial fractures, 4-8 months for femoral fractures. Protection in cast/brace for 4-6 weeks post-removal to prevent refracture. For Ilizarov bone transport, total treatment time may extend to 12-18 months.

Month 12+

Long-term Rehabilitation & Monitoring

Intensive physical therapy to regain strength and motion after prolonged immobilization, gait training, gradual return to activities, monitoring for late complications (malunion, nonunion, chronic osteomyelitis, pin tract scars), and functional outcome assessment. Some joint stiffness is common after severe open fractures despite optimal treatment.

Tips for Faster Recovery

Perform pin site care twice daily: clean with sterile saline or chlorhexidine, observe for signs of infection (redness, swelling, discharge, pain), never allow crusts to build up around pins

Avoid bumping or catching the external frame on objects as this can loosen pins or displace fracture

Keep wounds clean and dry; avoid submerging in water (showering allowed with waterproof covering, no bathing/swimming)

Report immediately: fever, increasing pain, foul-smelling drainage, pin loosening, numbness/tingling, color changes in extremity

Maintain range of motion exercises for joints above and below frame daily to prevent permanent stiffness

Follow weight-bearing restrictions precisely as excessive loading can cause loss of reduction or pin loosening

Attend all follow-up appointments for frame adjustments, X-rays, and wound checks - typically weekly initially, then every 2-3 weeks

Nutrition is critical for bone healing: high protein diet (1.5g/kg/day), calcium 1200mg, vitamin D 2000IU, adequate calories

For Ilizarov frames with gradual distraction: turn adjustment mechanisms precisely as instructed (typically 1mm/day divided into 4 turns)

Psychological support important as external fixation is prolonged, visible, and impacts daily activities - connect with support groups

Frequently Asked Questions

Common questions about this procedure

Q1.When is external fixation used instead of internal fixation (plates/rods)?

External fixation is preferred when there is severe soft tissue damage, contaminated open wounds (Gustilo Type II/III), active infection precluding implants, vascular injury requiring repeated surgical access, polytrauma requiring damage control, severe comminution with bone loss, or when definitive internal fixation is unsafe initially. It allows fracture stabilization while maintaining access to wounds for debridement and soft tissue procedures. Once soft tissues heal (typically 10-21 days), conversion to internal fixation may be performed if appropriate, or external fixation continued until union.

Q2.How do I care for pin sites to prevent infection?

Clean pin sites twice daily with sterile saline or dilute chlorhexidine solution using sterile gauze. Gently remove any crusts (do not allow buildup as this harbors bacteria). Observe for warning signs: increasing redness beyond 1cm from pin, purulent drainage, pain, pin loosening, or fever. Apply sterile dressing if drainage present. Avoid ointments as they trap moisture. Report early signs of infection immediately as pin tract infections occur in 10-30% of cases and can progress to deeper bone infection (osteomyelitis). Some serous drainage and mild pink skin for the first 2mm around pins is normal.

Q3.Can I shower or bathe with an external fixator?

You may shower with the external fixator using waterproof barriers (plastic bags sealed with waterproof tape) to protect pin sites from water exposure. Pat dry immediately after showering. Do NOT take baths, go swimming, or submerge the limb in water as this significantly increases infection risk. Some surgeons allow gentle showering over the frame after 2 weeks if wounds are healed, but always confirm with your surgeon. Keep all wounds and pin sites clean and dry between showering.

Q4.What is the Ilizarov method and when is it used?

The Ilizarov method uses a circular external fixation frame with thin wires under tension connected to rings around the limb. It is used for complex problems: bone transport (gradually moving bone segments to fill defects), limb lengthening (growing new bone through distraction osteogenesis), correction of severe deformities, nonunion treatment, and infected fractures requiring bone resection. Treatment involves gradual mechanical adjustments (typically 1mm per day divided into 4 adjustments) over many months. While technically demanding and requiring prolonged treatment (often 12-18 months), Ilizarov techniques can salvage limbs that would otherwise require amputation.

Q5.How long until the external fixator is removed?

Timing varies by fracture type and treatment plan. For temporary damage control fixation: typically 10-21 days until conversion to internal fixation once soft tissues permit. For definitive external fixation: 3-6 months for tibial shaft fractures, 4-8 months for femoral fractures, and potentially 12-18 months for complex Ilizarov bone transport procedures. Removal requires both clinical union (no pain or motion at fracture site) and radiographic union (bridging callus across at least 3 of 4 cortices on orthogonal X-rays). After removal, protection in a cast or brace for 4-6 weeks is standard to prevent refracture through the weakened pin sites.

Q6.What are the main complications of external fixation?

Pin tract infection (10-30% of cases) is most common, ranging from superficial skin infection to deep osteomyelitis requiring pin removal or antibiotics. Other complications include: pin loosening requiring replacement (5-10%), joint stiffness from prolonged immobilization, malunion/nonunion (especially if frame not adequately rigid), neurovascular injury during pin insertion (rare with proper technique), refracture after frame removal through pin holes (prevented by post-removal bracing), and psychological impact from visible, cumbersome frame affecting daily activities. Despite these risks, external fixation remains invaluable for managing complex open fractures and preventing amputations in severe injuries common in Bihar's road traffic and agricultural accidents.

Q7.Can external fixation be used for all bones?

External fixation can be applied to most long bones (tibia, femur, humerus, radius/ulna) and pelvis. It is most commonly used for tibial fractures due to the thin soft tissue coverage making internal fixation high-risk for wound complications. Femoral external fixation is typically temporary (damage control) as the thick muscle envelope and high forces make definitive external fixation less ideal. Upper extremity (humerus, forearm) fixation is less common but used for severe open injuries. Circular frames (Ilizarov) can be applied to virtually any bone including foot and ankle. The specific frame design varies by bone, fracture pattern, and soft tissue condition.

Q8.Will I have permanent scars or problems from the pin sites?

Small scars at pin insertion sites are expected, typically 5-10mm diameter each. Most heal well after frame removal with minimal cosmetic impact. Rare complications include: hypertrophic scarring (thick, raised scars), chronic sinus tracts (persistent drainage requiring surgical closure), bone heterotopia (bone formation in soft tissue around pins), and permanent bone defects from infected pins requiring curettage. To minimize scarring: meticulous pin care, early infection treatment, and avoiding excessive pin motion (bumping frame). Any concerning drainage, pain, or non-healing sites after frame removal should be evaluated as chronic osteomyelitis may require surgical debridement.

Q9.When is conversion from external to internal fixation done?

Conversion is typically planned for temporary external fixation applied in damage control scenarios. Timing: usually 10-21 days after injury once soft tissue swelling resolved, wounds clean/closed, and patient medically stable. The "safe period" is before 14-21 days (before biofilm and bacteria colonize pins) or after 6+ weeks once pin tracts epithelialized. Conversion between 3-6 weeks carries highest infection risk. Technique involves removing external fixator, gentle debridement of pin tracts, and applying definitive internal fixation (plate or intramedullary nail) in the same surgery. Prophylactic antibiotics are essential. Some cases require leaving external fixation as definitive treatment if soft tissues remain tenuous or infection present.
