Arthroscopic Assisted Distal Radial Ulnar Joint Reconstruction Using a Modified Anatomic Ligament Reconstruction

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Hand and Wrist Surgery

Background:

• Distal radioulnar joint (DRUJ) instability often results from triangular fibrocartilage complex injuries.
• Acute injuries may be successfully repaired, but chronic instability or failed repairs require reconstructive strategies.
• Traditional open reconstructions are technically demanding and can compromise stabilizing structures.

Purpose of the Study:

• To describe a simple and effective arthroscopic reconstruction method for DRUJ instability.
• To restore and reinforce the native anatomy of the DRUJ's critical stabilizers.
• To present an alternative to traditional open techniques, preserving secondary stabilizers.

Main Methods:

• Arthroscopic reconstruction utilizing an extrinsic radioulnar soft tissue link.
• Focus on preserving ulnocarpal and DRUJ secondary stabilizers.
• Anatomic graft passage and foveal bone tunnel placement facilitated by arthroscopic visualization.

Main Results:

• The described arthroscopic method provides excellent visualization for graft placement.
• It allows for preservation of critical secondary stabilizers of the DRUJ.
• The technique aims to restore and reinforce the native anatomy for improved stability.

Conclusions:

• Arthroscopic reconstruction is a viable and effective option for chronic DRUJ instability.
• This technique offers advantages over traditional open methods by preserving stabilizing structures.
• It provides a simpler approach to restoring DRUJ stability and function.
