Area of Science:

  • Orthopedics
  • Anatomy
  • Biomechanics

Background:

  • The distal radioulnar joint (DRUJ) is a highly evolved and specialized structure.
  • Its function relies on the interplay of the triangular fibrocartilage complex (TFCC), ligaments, and distal interosseous membrane.

Purpose of the Study:

  • To review the phylogenic development and functional anatomy of the DRUJ.
  • To highlight the current understanding and limitations in diagnosing and treating DRUJ pathologies.

Main Methods:

  • Phylogenic review of the DRUJ.
  • Analysis of anatomical structures contributing to DRUJ function.
  • Review of advancements in diagnostic imaging and arthroscopy.

Main Results:

  • The DRUJ facilitates forearm rotation and stability while transmitting loads.
  • Improved diagnostic tools allow for more precise diagnosis and treatment planning.

Conclusions:

  • Despite advancements, a complete understanding of DRUJ pathophysiology remains elusive.
  • Further investigation is essential to reconcile theoretical knowledge with clinical experience for improved patient outcomes.
