Biomechanics of Upper Extremity Double Plating

Area of Science:

• Orthopedic Surgery
• Traumatology
• Biomechanics

Background:

• Double plating (DP) is an established surgical technique in traumatology.
• It is the standard of care for specific fractures like bicondylar tibial plateau and distal humeral fractures.
• The principles of DP are increasingly being explored for broader applications and revision cases.

Purpose of the Study:

• To review the biomechanical evidence supporting the use of double plating in the upper extremity.
• To explore the advantages of DP in various anatomical locations and fracture types.
• To summarize the current literature on the biomechanics of upper extremity DP.

Main Methods:

• Literature review of published studies on the biomechanics of double plating in the upper extremity.
• Analysis of biomechanical advantages in different anatomical regions and fracture complexities.
• Synthesis of evidence regarding stability, fixation, and soft-tissue considerations.

Main Results:

• DP provides multiplanar stability, beneficial in areas with high torsional, bending, or traction forces.
• Two smaller implants can replace one larger implant, increasing fixation points and improving stability.
• DP minimizes soft-tissue irritation compared to single, bulkier implants.
• Biomechanical evidence supports DP for clavicle, humeral shaft, proximal humeral, and olecranon fractures, in addition to established uses.

Conclusions:

• Double plating offers significant biomechanical advantages, including enhanced stability and reduced soft-tissue complications.
• Its application can be expanded beyond traditional indications, particularly for complex and revision fractures.
• The technique provides a superior alternative to single plating in specific upper extremity fracture scenarios.
