Editing Metacarpal bones (section)

=== Congenital disorders ===
The fourth and fifth metacarpal bones are commonly "blunted" or shortened, in [[pseudohypoparathyroidism]] and [[pseudopseudohypoparathyroidism]].

A blunted fourth metacarpal, with normal fifth metacarpal, can signify [[Turner syndrome]].

Blunted metacarpals (particularly the fourth metacarpal) are a symptom of [[nevoid basal-cell carcinoma syndrome]].
