Clinical Scorecard: Comparative Analysis of Radiopalmar Double Plating Versus Traditional Palmar Plating in Complex Distal Radius Fractures

At a Glance

Key Highlights

• Palmar locking plate osteosynthesis is standard for distal radius fractures, but complex fractures with dorsoradial comminution remain challenging.
• Supplementary radial buttress plating may improve stability in fractures involving the radial styloid process.
• Biomechanical cadaveric study compared palmar plating alone versus combined palmar and radial plating in an AO/OTA 2R3 C2.1 fracture model with dorsoradial defect.

Guideline-Based Recommendations

Diagnosis

• Use quantitative computed tomography (qCT) to assess bone mineral density and fracture characteristics.
• Identify metaphyseal dorsoradial comminution and articular involvement via imaging.

Management

• Perform palmar variable-angle locking plate osteosynthesis aligned along watershed line and shaft axis.
• Consider additional radial buttress plating via a pre-bent 6-hole radial VA LCP plate for improved fixation in complex fractures.
• Limit screw occupancy on radial plate to minimize surgical exposure while providing buttress support.

Monitoring & Follow-up

• Monitor fixation stability intraoperatively and postoperatively, especially in osteoporotic bone.
• Assess tendon tension and radial fragment displacement under simulated physiological loads.

Risks

• Implant-related complications are common in severe osteoporosis and multifragmentary fractures.
• Extended surgical exposure may increase risk; limited screw fixation on radial plate recommended to reduce this.

Patient & Prescribing Data

Patients with complex distal radius fractures involving dorsoradial metaphyseal comminution, including elderly with osteoporosis

Radiopalmar double plating may provide biomechanical advantages over palmar plating alone by acting as a buttress against fragment displacement, potentially reducing implant-related complications.

Clinical Best Practices

• Use variable-angle locking plates for fragment-specific fixation in multifragmentary distal radius fractures.
• Incorporate radial buttress plating selectively for fractures involving the radial styloid to enhance stability.
• Pre-bend radial plates to conform anatomically and minimize soft tissue disruption, preserving brachioradialis tendon.
• Limit screw insertion on radial plate to essential fixation points to reduce surgical exposure and preserve soft tissue.
