The os centrale carpi is an accessory ossicle of the wrist positioned dorsally between the scaphoid, the trapezoid and the capitate bones . As with most other accessory ossicles of the wrist, the os centrale carpi is a rare finding on imaging and is, in the majority of cases, an asymptomatic anatomic variant.

Epidemiology

It has an incidence of 0.3-1.6% .

Development

It is thought to represent a separate ossification center that is seen in the embryo at 6 weeks, that then normally fuses with the distal ulnar portion of the scaphoid at 8 weeks .

Differential diagnosis

Related pathology

Os centrale carpi have been observed to cause symptoms such as intermittent pain, clicking and crepitus due to its mobility in the carpus. Osteonecrosis of the os centrale carpi has been reported after trauma .
