Background:

Palmar dislocation of the trapezoid bone is an uncommon wrist injury.
It typically results from substantial direct or indirect trauma to the wrist.
Associated bony or ligamentous injuries are frequently observed.

Observation:

This case report details a new instance of palmar trapezoid dislocation.
The study emphasizes the importance of recognizing this injury to prevent adverse outcomes.
Radiographic findings are a key focus in the literature review.

Findings:

Open reduction and internal fixation is the preferred treatment method.
This surgical approach generally yields favorable functional results for patients.
Early diagnosis and intervention are critical for optimal outcomes.

Implications:

Unrecognized trapezoid dislocations can lead to chronic pain and functional deficits.
Delayed treatment may increase the risk of developing post-traumatic osteoarthritis.
Accurate radiographic assessment is essential for guiding surgical management and improving patient prognosis.
