Arthroscopic-Assisted Inside-Out Foveal Reattachment of Triangular Fibrocartilage Complex

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Upper Extremity Reconstruction

Background:

• The triangular fibrocartilage complex (TFCC) is crucial for distal radioulnar joint (DRUJ) stability.
• DRUJ instability often requires surgical reattachment of TFCC deep components to the ulnar fovea.
• Current arthroscopic techniques include transosseous tunnels or bone anchors, with outside-in suturing being common.

Purpose of the Study:

• To present a novel arthroscopic inside-out TFCC-foveal reattachment technique using a bony anchor.
• To evaluate the advantages of this new technique for treating DRUJ instability.

Main Methods:

• Arthroscopic inside-out TFCC-foveal reattachment using a bony anchor.
• Focus on reattaching dorsal and palmar radioulnar ligaments to the ulnar head fovea.
• Comparison implied with existing transosseous and outside-in bone anchor techniques.

Main Results:

• The presented inside-out technique offers reduced surgical exposure.
• It involves less soft-tissue dissection compared to traditional methods.
• The technique facilitates easier suturing of the TFCC.

Conclusions:

• The arthroscopic inside-out TFCC-foveal reattachment with a bony anchor is a viable option for DRUJ instability.
• This technique provides potential benefits in terms of surgical invasiveness and ease of execution.
• It represents a valuable addition to the surgical armamentarium for TFCC injuries.
