Weight Bearing After Proximal Femoral Nail for Comminuted Intertrochanteric Fracture

Evidence-Based Weight Bearing Protocol

• Full weight bearing as tolerated is recommended immediately after surgery for all intertrochanteric fractures treated with cephalomedullary nail fixation, regardless of fracture stability or comminution pattern, according to the American Academy of Orthopaedic Surgeons guidelines 1, 2
• The American Academy of Orthopaedic Surgeons guidelines specifically state this as a "limited strength option" based on available evidence, but it represents the current standard of care for these injuries 1

Critical Caveats and Contraindications

• Inadequate reduction, suboptimal implant positioning, and pathologic fractures are contraindications for immediate weight bearing, as stated by Praxis Medical Insights 2
• Anatomic reduction with restoration of medial cortical continuity is necessary before allowing weight bearing, to prevent malunion and hardware failure, as recommended by Praxis Medical Insights 2

Practical Implementation

• The American Academy of Orthopaedic Surgeons recommends providing assistive devices, such as walkers or crutches, for the first 2-3 weeks to aid balance and confidence, even though full weight bearing is permitted 1
• Referral for bone health evaluation and osteoporosis treatment is recommended to address the underlying pathology and reduce future fracture risk, according to the American Academy of Orthopaedic Surgeons and Praxis Medical Insights 1, 2
