Derotation taping for metacarpal and phalangeal fractures.

Derotation taping for metacarpal and phalangeal fractures is a simple, noninvasive technique for management of acute fractures with malrotation. Ulnar nerve or ring block is performed followed by a closed reduction using a Jahss technique and then a rotatory manipulation. Plaster tape is applied, providing a supination torque on the finger. Those patients with a late presentation of a rotatory malunion are managed with a "K wire osteoclasis" which involves multiple percutaneous cortical K-wire perforations and then a manipulation.
