BMC musculoskeletal disorders·2025

Experimental traumatic triangular fibrocartilage complex (TFCC) lesions significantly impact wrist stability. Specifically, ulnar avulsion with ulnar styloid fracture (1B-2) and distal avulsion with ligament injury (1C) substantially decrease wrist stability.

Area of Science:

  • Orthopedics
  • Biomechanics
  • Hand Surgery

Context:

  • The triangular fibrocartilage complex (TFCC) is crucial for wrist stability.
  • Traumatic TFCC lesions are common and can lead to significant wrist dysfunction.
  • Understanding the biomechanical impact of different TFCC lesions is essential for effective treatment.

Purpose:

  • To investigate the biomechanical effects of experimental traumatic triangular fibrocartilage complex (TFCC) lesions on wrist stability.
  • To quantify changes in wrist torque under various lesion conditions.
  • To establish theoretical criteria for guiding clinical management of TFCC injuries.

Summary:

  • Fourteen cadaver upper extremities underwent biomechanical testing using an INSTRON 8874.
  • Experimental lesions included central perforation (1A), ulnar avulsion (1B-1, 1B-2), distal avulsion (1C), and radial avulsion (1D).

Published on: May 23, 2025

  • Ulnar avulsion with ulnar styloid fracture (1B-2) and distal avulsion with ligament injury (1C) significantly reduced wrist stability compared to dorsal arthrotomy.

    • Impact:

    • The study identifies specific TFCC lesions (1B-2 and 1C) that critically compromise wrist stability.
    • Findings provide a biomechanical basis for prioritizing surgical repair and treatment strategies for these severe TFCC injuries.
    • This research contributes to improved clinical decision-making and patient outcomes in managing traumatic wrist injuries.
