Fracture Fixation

Comprehensive Guide to Surgical Treatment, Recovery, and Long-Term Outcomes

Fracture fixation, also known as open reduction and internal fixation (ORIF), is a surgical procedure used to stabilize and heal broken bones. When conservative treatment (casting or bracing) is insufficient, internal fixation provides accurate alignment, early mobilization, and reliable healing for a wide range of fractures affecting the upper extremity, lower extremity, spine, and other skeletal sites.

Key Fact: Modern fracture fixation techniques, including locked plates, intramedullary nails, and advanced screws, have dramatically improved outcomes, reduced complication rates, and enabled patients to return to function faster than ever before. Success rates exceed 90% in appropriately selected cases.

Understanding Fracture Fixation

Fracture fixation involves surgically realigning broken bone fragments and securing them in place with internal devices to allow healing. Key benefits include:

• Accurate anatomic alignment of fracture fragments

• Early mobilization and reduced stiffness

• Faster return to function and activities

• Lower rates of malunion and deformity

• Better outcomes in complex fractures

• Improved pain management

• Early weight-bearing when appropriate

• Prevention of neurovascular compromise

Indications for Fracture Fixation

Primary Indications for Fracture Fixation:

1. Displaced Fractures - Fractures with significant displacement requiring anatomic reduction

2. Open Fractures - Fractures with skin/soft tissue disruption requiring precise alignment

3. Comminuted Fractures - Complex multi-fragment fractures requiring stabilization

4. Intra-Articular Fractures - Fractures extending into joints requiring anatomic reduction

5. Pathologic Fractures - Fractures through diseased bone requiring stabilization

6. Multiple Injuries - Polytrauma requiring early mobilization

7. Non-Union/Delayed Union - Previous fractures with poor healing

8. Specific Fracture Types - Femur, tibia, humerus, radius/ulna, ankle, pelvis, clavicle

Types of Fracture Fixation Methods

Plate and Screw Fixation

Metal plates secured with screws bridging the fracture site.

Advantages:

• Excellent for articular fractures

• Direct visualization possible

• Multiple screw options

• Versatile application

• Good for distal fractures

Intramedullary Nailing

Metal rod inserted through bone shaft; minimal soft tissue damage.

Advantages:

• Preserves blood supply

• Early weight-bearing

• Less soft tissue trauma

• Better for shaft fractures

• Faster healing

Lengthening Amounts and Expectations

Safe Fixation Guidelines

Key Principles:

• Achieve anatomic or near-anatomic reduction

• Obtain rigid fixation for early mobilization

• Avoid over-tightening which can cause stress riser

• Multiple fixation points provide stability

• Choice of method depends on fracture pattern

Benefits and Risks of Fracture Fixation

Complication Profile and Rates

Recovery Timeline After Fracture Fixation

Phases of Recovery

Immediate Post-Operative (Days 1-3)

Hospital stay with pain management, wound monitoring, and elevation. Initial physical therapy begins.

Early Phase (Weeks 1-4)

Wound healing continues. Early range of motion exercises initiated. Pain and swelling gradually decrease. Protected weight-bearing may begin for lower extremity fractures.

Intermediate Phase (Weeks 4-12)

Progressive increase in activity. Sutures/staples removed around week 2-3. Advancing strengthening exercises. Most patients return to driving and work activities. Pain significantly improved.

Late Phase (Months 3-6)

Bone healing progresses; union typically evident on imaging. Return to normal weight-bearing. Progressive return to sports/recreational activities. Continued strength rehabilitation.

Long-Term (6-12 Months+)

Complete functional recovery in most cases. Hardware may be removed if symptomatic (6-12+ months post-op). Maximum strength gains achieved. Return to all activities as cleared.

Typical Healing Times

• Femur: 4-6 months (faster with IM nail)

• Tibia: 3-6 months (varies by location)

• Humerus: 3-4 months

• Radius/Ulna: 2.5-4 months

• Ankle: 2.5-3.5 months

• Hand/Foot: 4-8 weeks

Rehabilitation and Physiotherapy

The Critical Role of Rehabilitation

Structured physical therapy is essential for optimal recovery. Early mobilization prevents stiffness, improves blood flow, reduces pain, and accelerates functional recovery. The rehabilitation approach varies by fracture type and fixation method.

Phase 1: Immediate Post-Op (Days 0-2 weeks)

Goal: Protect the surgical repair and manage pain.

Focus on gentle range of motion, pain control, elevation, and ice to reduce swelling.

Phase 2: Early Motion (Weeks 2-6)

Goal: Restore mobility and begin strengthening.

Progress active-assisted to active range of motion. Begin light resistance exercises.

Phase 3: Progressive Strengthening (Weeks 6-12)

Goal: Build strength and functional capacity.

Advance to resistance exercises, functional training, and gait normalization.

Phase 4: Return to Function (3+ Months)

Goal: Return to normal activities and sports.

Sport-specific training, work simulation, and conditioning.

Key Research Findings on Rehabilitation:

• Early mobilization improves outcomes significantly

• Protected weight-bearing accelerates healing

• Formal therapy better than home exercises alone

• Early passive range of motion prevents stiffness

• Resistance training restores strength (4+ months post-op)

• Progressive return to activity improves functional outcomes

Comparison: Plate & Screw vs. Intramedullary Nailing

Key Differences

Plate & Screw Fixation: Excellent for articular fractures and distal fractures. Provides direct visualization and multiple fixation points. Better for complex anatomy but may require larger incisions.

Intramedullary Nailing: Preferred for shaft fractures (femur, tibia). Preserves blood supply, allows earlier weight-bearing, and has faster healing times. Minimally invasive approach reduces soft tissue trauma.

Choice depends on: Fracture location, pattern, soft tissue condition, patient factors, and surgeon experience.

Outcomes by Fracture Type

Expected Union Times and Healing Rates:

• Femoral Shaft: 90-95% union rate; 4-6 months average; IM nailing superior for healing speed

• Tibial Shaft: 93-96% union rate with IM nailing; 5 months average; plate fixation: 3.5 months but higher complications

• Distal Radius: 90-95% excellent/good functional outcomes; 2.5-3.5 months healing

• Distal Femur (articular): 76-90% excellent/good results; 4-5 months union; early mobilization critical

• Ankle (trimalleolar): 70-90% satisfactory outcomes; 2.5-3.5 months; infection rates 1.8-3%

• Proximal Humerus: 70-82% good functional outcomes; 3-4 months; higher reoperation rates (30%)

Factors Influencing Healing and Outcomes

Patient Factors

• Age: Younger patients heal faster; older patients require more time

• Smoking: Significantly delays healing (avoid smoking 4+ weeks)

• Nutrition: Adequate protein and micronutrients essential

• Comorbidities: Diabetes, kidney disease may slow healing

• Medications: Steroids may impair healing

• Compliance: Adherence to rehabilitation critical for success

Fracture Factors

• Fracture Type: Simple fractures heal faster than comminuted

• Soft Tissue Injury: Open fractures have more complications

• Location: Metaphyseal fractures heal faster than diaphyseal

• Vascular Status: Good blood supply accelerates healing

Pre-Operative Optimization

Getting Ready for Fracture Fixation

• Medical Clearance: Ensure stable medical condition

• Nutritional Support: Build up reserves before surgery

• Smoking Cessation: Critical—stop 4+ weeks before surgery

• PT Instruction: Pre-operative education

• Anesthesia Assessment: Ensure tolerance for procedure

• Imaging Study: Confirm fracture pattern

• Social Support: Arrange help for recovery
