Lunotriquetral Ligament Repair Using Augmented Internal Brace

Area of Science:

• Orthopedic Surgery
• Hand and Wrist Surgery
• Sports Medicine

Background:

• Lunotriquetral (LT) ligament tears often occur with other carpal ligament injuries.
• This can lead to complete LT dissociation and Volarflexed Intercalated Segment Instability (VISI).
• Current operative techniques for wrist instability lack definitive evidence of superiority.

Purpose of the Study:

• To present a novel surgical technique for lunotriquetral ligament repair.
• To describe an augmented internal brace method addressing triquetral extension and lunate flexion.
• To highlight the biomechanical advantages of the proposed internal brace construct.

Main Methods:

• Description of a proposed surgical technique for LT ligament repair.
• Utilizing an augmented internal brace for ligament and capsule repair.
• Demonstration using figures and references from a case example.

Main Results:

• The augmented internal brace technique addresses triquetral extension and lunate flexion.
• The internal brace construct offers biomechanical superiority.
• The technique provides augmentation of ligament and capsule repair.

Conclusions:

• The presented technique offers a viable option for lunotriquetral ligament repair.
• Augmented internal bracing provides biomechanical advantages for wrist instability.
• Further evidence may support this technique's superiority in managing LT dissociation.
