Summary

Carpal dislocations are often missed, especially when associated with scaphoid fractures. Prompt surgical intervention is crucial for severe wrist injuries to prevent long-term instability and osteoarthritis.

Area of Science:

  • Orthopedic Surgery
  • Traumatology
  • Hand and Wrist Surgery

Background:

  • Carpal dislocations are frequently missed diagnoses, despite significant wrist trauma.
  • The severity of ligamentous tears correlates with the force of injury, with anterior lunate dislocations indicating severe lesions.
  • Associated scaphoid fractures often dictate treatment priority in complex wrist injuries.

Purpose of the Study:

  • To highlight the diagnostic challenges of carpal dislocations.
  • To emphasize the link between injury severity and ligamentous damage.
  • To discuss the implications of conservative versus surgical management for perilunate dislocations and associated fractures.

Main Methods:

  • Review of carpal dislocation cases with emphasis on missed diagnoses.
  • Analysis of injury mechanisms and their correlation with ligamentous injury severity.
  • Comparison of outcomes between conservative and surgical treatments for perilunate dislocations, particularly when scaphoid fractures are present.

Main Results:

  • Thirty percent of carpal dislocations are initially missed.
  • Anterior lunate dislocations represent more severe ligamentous injuries.
  • Conservative treatment frequently leads to carpal instability and subsequent wrist osteoarthritis.
  • Surgical treatment is increasingly indicated for displaced scaphoid fractures and ligamentous repairs.

Conclusions:

  • Carpal dislocations, especially those with associated scaphoid fractures, require high clinical suspicion.
  • Early and accurate diagnosis is critical to prevent chronic wrist problems.
  • Surgical management offers better outcomes for displaced perilunate dislocations and complex wrist injuries, addressing both bony and ligamentous damage.
