Area of Science:

  • Orthopedic Surgery
  • Hand and Wrist Trauma
  • Radiology

Background:

  • Carpal dislocations are uncommon wrist injuries.
  • Volar dislocation of the capitate is exceptionally rare.
  • Carpometacarpal joint injuries often involve complex trauma patterns.

Observation:

  • A case of volar capitate dislocation is presented.
  • This was associated with ulnar-sided carpometacarpal joint dislocation.
  • The injury mechanism involved forced dorsiflexion of the wrist.

Findings:

  • The capitate underwent rotation and volar displacement.
  • This specific injury pattern highlights a rare presentation of carpal instability.
  • Radiographic and clinical evaluation is essential for diagnosis.

Implications:

  • Increased awareness of this rare injury can improve diagnostic accuracy.
  • Timely diagnosis and treatment are vital for optimal patient outcomes.
  • Understanding complex carpal kinematics aids in managing severe wrist trauma.
