Summary

The triangular fibrocartilage complex (TFCC) has three distinct components. Its distal part suspends the ulnar carpus, while the proximal and collateral ligaments twist during rotation, with the internal portion acting as a cushion.

Area of Science:

  • Anatomy
  • Biomechanics
  • Orthopedics

Background:

  • The triangular fibrocartilage complex (TFCC) is crucial for wrist stability.
  • Understanding its functional anatomy is key to diagnosing and treating wrist injuries.

Purpose of the Study:

  • To investigate the functional anatomy of the TFCC.
  • To examine dynamic changes in the TFCC during wrist rotation.

Main Methods:

  • Dissection of 20 fresh cadavers.
  • Analysis of the TFCC from proximal and distal aspects.
  • Coronal sectioning to examine internal structures.

Main Results:

  • The TFCC was divided into three components: a stable distal hammock, a twisting proximal radioulnar ligament, and a twisting ulnar collateral ligament.

  • The internal TFCC portion was found to be loose, potentially acting as a shock absorber.

    • Conclusions:

    • The TFCC's distinct components contribute differently to wrist function.
    • The TFCC's structure allows for dynamic adaptation during rotation, with a cushioning mechanism for the internal portion.
