Bipartite scaphoid

Last revised by Dr Henry Knipe on 05 Sep 2022

A bipartite scaphoid is a rare example of a divided carpus. There is controversy whether this condition is congenital (i.e. normal variant) or post-traumatic. Bipartite scaphoids may be unilateral or bilateral.

Diagnosis

Diagnostic criteria have been proposed 3:

  • no history of traumatic injury
  • normal appearance of both parts
  • well-defined and rounded cortex, with a small joint-like space intervening
  • no scaphotrapeziotrapezoidal or radioscaphoid osteoarthritis
