Rotational deformity following metacarpal fracture.

Ninety-one consecutive patients with 98 metacarpal fractures were looked at prospectively for rotational deformity. Whilst a quarter had minor rotation of the fracture of less than 10 degrees, only five had more than this. In just two cases, was there rotational instability requiring operative intervention. Assessment of rotational deformity must include an end-on view of the finger-nail, as there is often restricted movement at the metacarpal phalangeal joint following fracture.
