Post-traumatic wrist osteoarthritis, including specific carpal bone conditions, remains common despite advances. Injury leads to instability, altered joint mechanics, and eventual cartilage degeneration.

Area of Science:

  • Orthopedics and Hand Surgery
  • Biomechanics
  • Rheumatology

Background:

  • Post-traumatic wrist osteoarthritis is a frequent complication despite improved understanding of carpal mechanics and ligament injuries.
  • Specific patterns of osteoarthritis affect carpal bones like scapholunate advance collapse wrist, scaphotrapeziotrapezoid arthritis, and lunotriquetral arthritis.
  • The common pathway involves instability and altered kinematics leading to degenerative changes.

Purpose of the Study:

  • To review the etiology, prevalence, and current evaluation and treatment of post-traumatic intercarpal osteoarthrosis.
  • To highlight the specific patterns of osteoarthritis in various carpal articulations.
  • To emphasize the importance of understanding these conditions for hand surgeons.

Main Methods:

  • Literature review focusing on carpal mechanics, intercarpal ligament injuries, and carpal instability.
  • Analysis of the pathophysiology of post-traumatic osteoarthritis in specific carpal joints.
  • Synthesis of current diagnostic and therapeutic approaches.

Main Results:

  • Osteoarthritis of the carpal bones, including scapholunate advance collapse wrist, scaphotrapeziotrapezoid arthritis, lunotriquetral arthritis, triquetrohamate arthritis, and pisotriquetral arthritis, follows distinct patterns.
  • The final common pathway involves instability and altered kinematics, resulting in abnormal joint contact pressures and cartilage degeneration.
  • Despite advances, post-traumatic intercarpal osteoarthrosis remains a significant clinical problem.

Conclusions:

  • Understanding the specific patterns and common pathway of post-traumatic intercarpal osteoarthrosis is crucial.
  • Effective evaluation and treatment strategies are essential for managing carpal instability and preventing degenerative changes.
  • This review underscores the importance of these conditions for hand surgeons managing wrist trauma.
