Arthroscopic Examination of the Triangular Fibrocartilage Complex in Galeazzi Injuries: Revisiting a Complex Injury.

Area of Science:

• Orthopedic Surgery
• Traumatology
• Arthroscopy

Background:

• Galeazzi fracture-dislocations are severe forearm injuries requiring precise surgical management.
• Instability and dysfunction can result if distal radioulnar joint injuries are not adequately addressed.
• The incidence and pattern of triangular fibrocartilage complex (TFCC) injuries in Galeazzi fractures remain understudied due to infrequent direct inspection.

Purpose of the Study:

• To investigate the incidence and characteristics of triangular fibrocartilage complex injuries in patients with Galeazzi fracture-dislocations.
• To highlight the potential for significant TFCC damage in these traumatic events.
• To emphasize the role of arthroscopy in evaluating TFCC integrity.

Main Methods:

• Retrospective review of six consecutive patients diagnosed with Galeazzi fracture-dislocations.
• Performance of wrist arthroscopy to directly visualize the triangular fibrocartilage complex.
• Documentation of tear patterns and extent of TFCC involvement.

Main Results:

• Arthroscopy revealed complex tears of the triangular fibrocartilage complex in all reviewed cases.
• Tears consistently involved large segments of the TFCC, particularly the dorsal periphery.
• A uniform pattern of disruption at the attachments of the TFCC was observed in all patients.

Conclusions:

• Galeazzi fracture-dislocations frequently result in severe, complex tears of the triangular fibrocartilage complex.
• Routine arthroscopic assessment is essential for accurate diagnosis of TFCC injuries in these fractures.
• Meticulous arthroscopic repair may be necessary for optimal management of these devastating injuries.
